Proteins are polymers of _____.
B: Amino acids
C: Nucleic acids
D: Fatty acids
The correct answer is option B.
Proteins are polymers of amino acids. So, the correct option is B.
Proteins are the organic compounds found in living organisms. They are diverse in structure and function than other macromolecules. In a single cell, thousands of protein molecules can be found with unique functions. Although all proteins are made up of chains of amino acids, they vary in structure and functions.
Proteins have a range of functions in a cell of living organisms. Enzymes and hormones are proteins in nature. Enzymes act as a catalyst that speeds up biochemical reactions.
For instance, salivary amylase enzyme breaks down starch into smaller sugar molecules. Similarly, hormones are proteins that control physiological functions such as metabolism, growth, development, and reproduction, etc.
Polymers are long chains that are made up of small subunits or building blocks of monomers. Polymers are like a chain of beads of monomers strung together. Proteins, nucleic acids, and carbohydrates are long polymers in nature.
Amino acids are the polymers that make up proteins. Specifically, one molecule of protein is made up of one or more linear chains of amino acids. These chains of monomers called a polypeptide. There are 202020 kinds of amino acids found in proteins.
Amino acids contain a central carbon atom which is also called the alpha (α) carbon. This carbon atom is bonded to a hydrogen atom and an amino group.
