Detailed explanation-1: -The difference in the side-chain group or R-group is what determines the unique properties of each amino acid.

Detailed explanation-2: -The carbon, carboxyl, and amino groups are common to all amino acids, so the R-group is the only unique feature in each amino acid.

Detailed explanation-3: -The twenty amino acids (that make up proteins)each have assigned to them both three-letter (can be upper or lower case) and one-letter codes (upper case). This makes it quicker and easier for notation purposes and are worth learning.

Detailed explanation-4: -All amino acids have the same basic structure. Each molecule has a central carbon atom linked together with a basic amino group, a carboxylic acid group, a hydrogen atom and an R-group, or side-chain group. The R-group is what sets the amino acids apart. The R-group determines each amino acid’s chemical nature.

Detailed explanation-5: -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.
