Most of the biological nutrients are macromolecules that are used by the body to carry out various life activities. These are made by the combination of monomers. Quiz Activity Of The Day! Put your understanding of this concept to test by answering a few MCQs.
What are the polymers of amino acids?
Proteins are the polymers of amino acids. These include the carboxylic and the amino group. There would be no lipids or carbohydrates without proteins because the enzymes used for their synthesis are proteins themselves.
What are the three types of carbohydrates?
Carbohydrates. Carbohydrates are polymers of carbon, hydrogen and oxygen . They can be classified as monosaccharides, disaccharides and polysaccharides . Carbohydrates are found in starch, fruits, vegetables, milk and sugars. They are an important source of a healthy diet.
How many types of macromolecules are there in the human body?
There are three main types of biological macromolecules, according to mammalian systems:
What are the different types of macromolecules?
In Summary: Different Types of Biological Macromolecules. Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds ...
What are the four macromolecules that are essential to life?
The four main macromolecules that are essential to life are proteins, lipids, carbohydrates, and nucleic acids . All four macromolecules are made up of the same four elements, just in different ratios and molecule configurations. Each macromolecule serves a unique purpose. Each macromolecule is made up of smaller subunits called monomers.
What are macromolecules made of?
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”
What type of reaction is when polymers are broken down into smaller units?
When polymers are broken down into smaller units (monomers), a molecule of water is used for each bond broken by these reactions; such reactions are known as hydrolysis reactions.
What is the name of the reaction where two molecules of glucose are linked together to form a disaccharide?
This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”. Figure 1. In the dehydration synthesis reaction depicted above, two molecules of glucose are linked together to form the disaccharide maltose. In the process, a water molecule is formed.
What are the elements that make up the majority of a cell's dry mass?
Combined, these molecules make up the majority of a cell’s dry mass (recall that water makes up the majority of its complete mass). Biological macromolecules are organic, meaning they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, and additional minor elements.
What are monomer and polymer reactions?
These reactions are similar for most macromolecules, but each monomer and polymer reaction is specific for its class. For example, in our bodies, food is hydrolyzed, or broken down, into smaller molecules by catalytic enzymes in the digestive system. This allows for easy absorption of nutrients by cells in the intestine.
What are the two types of macromolecules that make up sugar?
All sugars belong to a group of biological macromolecules known as carbohydrates. Carbohydrate molecules contain carbon , hydrogen and oxygen. These elements combine to form a sugar molecule. The nature of a carbohydrate depends on the number of sugar molecules bonded together and the orientation of the carbon, hydrogen and oxygen atoms. Humans use carbohydrates as the first source of energy. When you consume excess carbohydrates, the liver converts some into fat and stores a portion as the long chain sugar molecule glycogen. The human body does not use any other source of energy until glycogen reserves run out.
What are the four types of macromolecules?
Biological macromolecules fall into four categories: carbohydrates, proteins, lipids and nucleic acid s. Your body uses carbohydrates, lipids and proteins for energy. The only biological macromolecule not used for energy is nucleic acid. Nucleic acids hold and transcribe your genetic code.
What is the name of the macromolecule that contains DNA?
The biological macromolecule nucleic acid occurs in two forms: deoxyribonucleic acid, or DNA, and ribonucleic acid, commonly known as RNA . DNA contains the blueprint for your genetic code. RNA reads the blueprint found on DNA and produces proteins based on the genetic code. While you will only find DNA inside a cell, some RNA exists outside of the cell. The RNA outside of the cell manufactures proteins. The human body does not use nucleic acid for energy.
