What are the building blocks of proteins and how many are there?
Answer:
Proteins are macromolecules made up of smaller units known as amino acids. There are 20 different standard amino acids that serve as the building blocks of proteins. These amino acids can be arranged in various sequences to form a wide variety of proteins with different structures and functions. Each amino acid consists of a central carbon atom, an amino group, a carboxyl group, and a side chain (R group) that gives each amino acid its unique properties. The sequence of amino acids in a protein chain determines its overall structure and function. This sequence is dictated by the genetic information encoded in an organism’s DNA.
