What are 3 functions of triglycerides?
Triglycerides are lipids you obtain from food sources of fat, such as cooking oils, butter and animal fat. Triglycerides provide insulation that keeps you warm while protecting your internal organs with a layer of padding. They also play a role how your body uses vitamins. When you don't burn all the calories you consume, they're converted to ...
What is the molecular structure of triglycerides?
Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Alcohols have a hydroxyl (HO–) group. Organic acids have a carboxyl (–COOH) group. Alcohols and organic acids join to form esters. The glycerol molecule has three hydroxyl (HO–) groups and each fatty acid has a carboxyl group (–COOH).
What is a simple triglyceride and a mixed triglyceride?
Triglycerides in which the three fatty acid radicles are of the same kind are known as simple triglycerides. Tristearin, triolein, tripalmitin, etc., are examples of simple triglycerides. A mixed triglyceride is one in which the three fatty acid radicles are not all of the same kind. For example, distearo-olein (having two radicles of stearic ...
What are the subunits of triglycerides?
Triglycerides are made up of monomers of glycerol molecules each bonded to three fatty acid “tails.”. Click to see full answer. In this manner, what are the subunits of triglycerides?

What are the structures of triglycerides?
What type of structure are triglycerides? Triglycerides are triesters consisting of a glycerol bound to three fatty acid molecules. Alcohols have a hydroxyl (HO–) group. Organic acids have a carboxyl (–COOH) group.
What are the functions of triglycerides list?
Energy Storage Triglycerides provide your body with energy, but their main function is to store energy for later use. The food you eat contains calories in the form of carbohydrates, protein and fat. When you consume more calories than your body can use, it stores those calories in the form of triglycerides.
What is the function of triglyceride lipid?
Triglycerides are lipids (waxy fats) that give your body energy. Your body makes triglycerides and also gets it from the foods you eat. High triglycerides combined with high cholesterol raise your risk of heart attack, strokes and pancreatitis.
What is the function of triglycerides quizlet?
Functions of triglycerides include energy storage, cushioning, thermal insulation, binding organs together and absorptions of some vitamins. Phospholipids take part in cell membrane structure, fat digestion and helps in the structure of myelin sheaths around neurons within the human body.
What are the 3 types of triglycerides?
The three types of fatty acids that compose triglycerides are saturated, monounsaturated and polyunsaturated fatty acids. From these three types of fatty acids come the three types of triglycerides, or fats; saturated, monounsaturated and polyunsaturated triglycerides.
Why are fats called triglycerides?
The word "triglyceride" reflects the fact that a triglyceride consists of three ("tri-") molecules of fatty acid combined with a molecule of the alcohol glycerol ("-glyceride") that serves as the backbone in many types of lipids (fats).
What is the function of triglycerides in animals?
Triglycerides in animals and probably in plant seeds function as depots of energy. In mammals they are stored in adipose tissue until needed, at which time they are broken down to a molecule of glycerol and three molecules of fatty acid.
What is the chief function of triglycerides in humans and other animals?
Triglycerides (TGs) are the main constituent of animal fat and play an important role as transporters of fatty acids as well as serving as an energy source. TGs are broken down into fatty acids and glycerol, after which both can serve as substrates for energy producing and metabolic pathways.

Which molecule starts the structure of a triglyceride?
The main molecule that starts the structure of a triglyceride is glycerol. Glycerol is a three-carbon molecule with three hydroxyl groups on them. These hydroxyl groups are the site of an ester reaction with three fatty acid molecules. The fatty acids can be different types, and the fatty acid structure defines the type of triglyceride. The fatty acids are long chains of carbons with bonded hydrogens. These are the parts of the triglycerides that are used for energy production.
What type of bond is used to explain the hydrogens in a fatty acid chain?
The bonds of the fatty acid chains can be either trans or cis. Media attention has been focused on the dangers of trans fatty acid bonds. These bond types explain how the hydrogens are placed on the molecule in a three-dimensional space. Trans bonds have the hydrogen molecules on opposite sides of the chain. Cis bonds have the hydrogen atoms on the same side of the fatty acid chain.
Is a triglyceride a saturated or unsaturated fatty acid?
Triglyceride fatty acid tails can be saturated or unsaturated. Saturated fatty acid tails are all single bond carbons. This means that for each carbon, there are two hydrogens and two carbons attached. There are no double bonds in a saturated molecule. Unsaturated fatty acids have at least one double bond. Single bond molecules are called monosaturated. A molecule that contains more double bonds is called polyunsaturated.
What are the functions of triglycerides?
One of the most important functions of triglycerides is the absorption of nutrients, such as fat-soluble vitamins A, D, E, and K. Human body is almost incapable of absorbing these nutrients without the help of these lipids. When triglyceride levels are too low, our body will not be able to get sufficient nutrients, which can cause vitamin deficiency and malnutrition.
What is the role of tricycerides in the body?
1. Protect Internal Organs. Triglycerides build the adipose tissue which is also known as subcutaneous fat that is located just below the skin. This tissue acts as the main fat storage and has the protective role.
What to do if you have a high triglyceride level?
In case you have a very high level of triglycerides (above 500 mg/dL), your doctor will probably advise you to start taking some medications like niacin, statins or fibrates to restore the functions of triglycerides. Nevertheless, remember that trying to lower your triglycerides with drugs alone won't diminish the chance of developing a stroke or a heart attack, which means that you should also watch what you eat and stay physically active.
Why can't triglycerides mix with water?
However, unlike phospholipids, triglycerides aren't able to mix with water due to their hydrophobic characteristic, which prevents them from merging into membranes. Triglycerides are attaching themselves to lipoproteins which permit them to travel through the bloodstream.
What happens if your triglycerides are above 500?
Levels of triglycerides that exceed 500 mg/dL could lead to the development of the life-threatening inflammation of the pancreas, also known as acute pancreatitis.
What are the risks of high triglycerides?
The Risks of High Triglycerides 1 Hypertriglyceridemia, the condition of having a high level of triglycerides in blood, is actually quite dangerous. It increases the risk of acquiring coronary artery disease, and can also lead to the blocking of your arteries, which will ultimately result in a stroke or a heart attack. 2 Those suffering from diabetes, kidney problems, or hypothyroidism are at high risk of acquiring complications from hypertriglyceridemia. 3 Levels of triglycerides that exceed 500 mg/dL could lead to the development of the life-threatening inflammation of the pancreas, also known as acute pancreatitis.
How to lower triglycerides?
You should consume more of these foods to lower your triglycerides levels. 4. Start Consuming More Omega-3 Fatty Acids. Omega-3 fatty acids can be found in fatty fish like herring, lake trout, salmon, and sardines.
Where do triglycerides come from?
They are found in foods that come from both plants and animals. The triglycerides in plants come from vegetable oils, such as sunflower and peanut, which remain liquid at room temperature. Meat and dairy products contain triglycerides in animal fats, which remain solid at room temperature.
What is the health impact of triglycerides?
Health Impact. Triglycerides serve a necessary function -- without them your body would run out of energy unless you were eating constantly. The American Heart Association warns that an elevated triglyceride level, a condition known as hypertriglyceridemia, is associated with coronary artery disease.
How high should triglycerides be?
Doctors recommend a triglyceride level of 150 milligrams per deciliter or less to reduce your risk of heart disease. A level of 200 to 499 milligrams per deciliter is considered high, and a level above 500 milligrams per deciliter is very high.
What are the most common lipids in the body?
Triglycerides are the most common lipid found in the body. They contain three chains of fatty acids. Although similar in structure to the phospholipids that build cell membranes, triglycerides are completely hydrophobic, meaning they cannot mix with water, so they cannot integrate into membranes.
Is triglyceride a solid?
Meat and dairy products contain triglycerides in animal fats, which remain solid at room temperature. Triglycerides are necessary for certain bodily functions, but high levels of them can lead to health problems.
How many molecules are in a triglyceride?
A triglyceride molecule is made up of 3 molecules of fatty acids that are connected to a glycerol molecule.
Why is it important to maintain healthy triglycerides?
So, maintaining healthy triglyceride levels is necessary so that it remains our ally and does not turn into an enemy in our body.
What is the fat in the adipose tissue?
The fat in the adipose tissue is primarily present in the form of triglycerides. This fatty tissue covers the internal organs and protects them from physical 'trauma' or 'shock'. Organs such as the heart, liver, and the kidneys are encased within the adipose tissue that acts as a cushion against shock, jarring and sudden movement of the body.
What would happen if there were no triglycerides?
If there were no triglycerides, our body would have had a tough time protecting its internal organs. Triglycerides form the adipose tissue, which lies below the skin. Also referred to as subcutaneous fat, the adipose tissue acts as a primary fat storage site.
What is the function of triacylglycerol?
Structure and Function of Triacylglycerol (Triglyceride) Triacylglycerols, better known as triglycerides, are a type of fat that serve to meet the energy needs of the body as well as protect internal organs from traumatic injuries. This Bodytomy post elaborates more on the triaglycerol structure and function.
Which tissue acts as a thermal insulator?
The adipose tissue, that is essential made up of triglycerides and located below the skin, acts as the body's thermal insulator. The connective tissue plays a key role in minimizing dissipation of heat through the skin.
When are triglycerides broken down?
However, when there is increased demand for energy, triglycerides are broken down into fatty acids to generate energy. For instance, during prolonged physical activity or fasting, oxidation of fatty acids takes place to meet the increased energy demands of the body.
What is the function of triglycerides?
The main function of triglycerides is to store fat and to provide living organisms with the energy for metabolism.
How do triglycerides convert into glucose?
The glycerol component of triglycerides can be converted into glucose via gluconeogenesis to serve as the source of energy for the brain.
How many fatty acids are in triglycerides?
Instead of three fatty acids attached as in triglycerides, however, there are two fatty acids forming diacylglycerol, and the third carbon of the glycerol backbone is occupied by a modified phosphate group.
How are tricycerides broken down?
Triglycerides are broken down to CO 2 and water, releasing large amounts of energy, through beta oxidation of fatty acids and the citric acid cycle.
Which molecule has an ester bond?
In the triglyceride molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through an oxygen atom.
What is the name of the alcohol that has a hydroxyl group attached to each carbon?
