Because the chain has fewer hydrogen atoms, it is said to be "unsaturated.". A fatty acid with one double bond is called "monounsaturated" because it has one gap. Fatty acids having more than one gap are called "polyunsaturated.". The fat in foods contains a mixture of saturated, monounsaturated and polyunsaturated fatty acids.

What is the structural difference between a polyunsaturated fat and a saturated fat?
The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain.
What is the difference between saturated monounsaturated and polyunsaturated fats quizlet?
When there are no double bonds between carbon atoms, it is called a saturated fatty acid (the carbon chain is "saturated" with hydrogen atoms). If there is one double bond between carbon atoms, it is called a monounsaturated fatty acid, and if there are 2 or more double bonds it is called polyunsaturated fatty acid.
What is the structural difference between saturated and unsaturated fatty acids quizlet?
-Saturation: Saturated fatty acids have all single bonds between the carbons making them more solid at room temperature. Unsaturated fatty acids have a double bond, making them more liquid at room temperature.
What is the main difference between a saturated fatty acid and a monounsaturated fatty acid?
1: Fatty Acids: Saturated fatty acids have hydrocarbon chains connected by single bonds only. Unsaturated fatty acids have one or more double bonds. Each double bond may be in a cis or trans configuration. In the cis configuration, both hydrogens are on the same side of the hydrocarbon chain.
What is the Difference Between Monounsaturated and Polyunsaturated Fats?
Monounsaturated fats are fatty acids that have only one unsaturated carbon bond whereas Polyunsaturated fats are fatty acids having more than one unsaturated carbon bonds. Moreover, Monounsaturated fats have only one carbon-carbon double bond. On the other hands, Polyunsaturated fats have more than one carbon-carbon double bonds.
What are Polyunsaturated Fats?
Polyunsaturated fats are fatty acids having more than one unsaturated carbon bonds. An unsaturated carbon bond is a double bond between two carbon atoms. Therefore, these fats have many double bonds between the carbon atoms. The oils having these fatty acids are liquid at room temperature but solidifies when chilled. Ex: olive oil.
What are some examples of monounsaturated fats?
Some examples of monounsaturated fats include myristoleic acid, palmitoleic acid, vaccenic acid, oleic acid, etc. The health benefits of these fats include decreased risk for breast cancer, reduce cholesterol levels, lower risk for heart diseases and helpful for weight loss.
Which type of fat has more than one carbon-carbon double bond?
On the other hands, Polyunsaturated fats have more than one carbon-carbon double bonds. Monounsaturated fats do not provide us with essential fats while Polyunsaturated fats provide us with essential fats such as omega-3 that the body cannot produce.
Which fat has the highest viscosity?
Since the viscosity and melting temperature of a fatty acid increase with the decreasing number of double bonds, monounsaturated fats have higher viscosity and melting temperatures when compared with other fatty acids. Some examples of monounsaturated fats include myristoleic acid, palmitoleic acid, vaccenic acid, oleic acid, etc.

Why are polyunsaturated fats important?
Polyunsaturated fats also include the omega-3 and omega-6 fatty acids, which are called essential fatty acids because they cannot be synthesized by the body, and therefore must be supplied by the food you eat. These omega fatty acids are crucial for normal brain function and cell growth.

solution is heated to boiling. While cooling, solubility of impurities decreases and pure compound crystals begin to form. Pure crystals are rinsed with cold solvent to remove impurities clinging to the surface, leaving pure compound behind. recrystallization.
Why doesn't trimyristin dissolve?
Trimyristin would not dissolve because it is a non-polar molecule. It also does not have a carboxylic acid group like myristic acid.
Can you extract trimyrisitn from nutmeg?
Water would not be suitable or extracting trimyrisitn from nutmeg because it is insoluble in water.

Instead we will be using dichloromethane because trimyristin is soluble in that liquid.
