The difference between one amino acid and another is found in the
|
|
amino group
|
|
|
carboxyl group
|
|
|
R-group
|
|
|
peptide bonds
|
Explanation:
Detailed explanation-1: -The alpha carbon also binds to an R-group, which differs from one amino acid to another and confers the amino acid with its acidic, basic or neutral properties.
Detailed explanation-2: -Proteins are chains of amino acids that assemble via amide bonds known as peptide linkages. The difference in the side-chain group or R-group is what determines the unique properties of each amino acid.
Detailed explanation-3: -Figure 2. There are 20 common amino acids commonly found in proteins, each with a different R group (variant group) that determines its chemical nature.
