Detailed explanation-1: -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-2: -Structure of an Amino Acid Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. This R group, or side chain, gives each amino acid proteins specific characteristics, including size, polarity, and pH.

Detailed explanation-3: -Each R-group or side chain of the 20 naturally occurring amino acids are different from one another. The R-group dictates the properties (size and structure) and nature of the amino acid (polarity). It determines if the amino acid is considered acidic, polar, nonpolar, basic, or neutral.

Detailed explanation-4: -An R-Group is a side chain attached to the -carbon of all amino acids. It decides the chemical versatility of the amino acid. For example, some R-Groups carry a charge, creating a polar molecule. Some R-groups are hydrophobic or hydrophillic.

Detailed explanation-5: -Classification: There are basically three major classifications for amino acids (1) those with nonpolar R group, (2) those with uncharged polar R groups, and (3) those with charged polar R group.
