Detailed explanation-1: -The 20 naturally occurring amino acids have the ability to make 75, 000 different proteins because each difference in the amino acid sequence is a different protein. One change of an amino acid from the sequence is considered to be a new protein. It is also accepted if the protein has a repeating unit of one amino acid.

Detailed explanation-2: -Your body needs 20 different kinds of amino acids to function correctly. These 20 amino acids combine in different ways to make proteins in your body.

Detailed explanation-3: -100, 000 proteins-all made of just 20 amino acids!

Detailed explanation-4: -There are a total of twenty-one amino acids, all of which are responsible for different roles throughout the body. Each amino acid is a large block of proteins, all different shapes, and sizes. In fact, some amino acid strands form together to create larger shaped proteins.
