BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The three parts to an amino acid include the amino group, the carboxyl group, and the side-chain or R group all attached to the -carbon. The R group is the part that distinguishes one amino acid from the next.

Detailed explanation-2: -Amino acids differ from each other with respect to their side chains, which are referred to as R groups. The R group for each of the amino acids will differ in structure, electrical charge, and polarity.

Detailed explanation-3: -The R group determines the characteristics (size, polarity, and pH) for each type of amino acid. Peptide bonds form between the carboxyl group of one amino acid and the amino group of another through dehydration synthesis.

Detailed explanation-4: -The difference in the side-chain group or R-group is what determines the unique properties of each amino acid.

Detailed explanation-5: -They all have a basic amino group and an acidic carboxylic acid group. The different amino acids differ in their structures based on the identity of their side chains which is labeled in the structure as an R group. This group makes one amino acid unique from other amino acids.
