BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -Since each of the 20 amino acids is chemically distinct and each can, in principle, occur at any position in a protein chain, there are 20 × 20 × 20 × 20 = 160, 000 different possible polypeptide chains four amino acids long, or 20n different possible polypeptide chains n amino acids long.

Detailed explanation-3: -The essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. The nonessential amino acids are alanine, asparagine, aspartic acid, glutamic acid, and serine.

Detailed explanation-4: -Your body needs 20 different amino acids to grow and function properly. While all 20 of these are important for your health, only 9 are classified as essential ( 1 ). These are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Detailed explanation-5: -Think about actual muscle tissue-it is comprised of all 20 amino acids, not just the BCAAs. To create new tissue, you need all 20 amino acids present.
