Detailed explanation-1: -The R groups have a variety of shapes, sizes, charges, and reactivities. This allows amino acids to be grouped according to the chemical properties of their side chains. For example, some amino acids have polar side chains that are soluble in water; examples include serine, threonine, and asparagine.
Detailed explanation-2: -Two amino acids have acidic side chains at neutral pH. These are aspartic acid or aspartate (Asp) and glutamic acid or glutamate (Glu).
Detailed explanation-3: -If the R group contains a basic group, the overall charge of the amino acid will not be neutralized by one acidic group present. So, the amino acid will be basic in nature. Example-lysine. Non-polar R groups contain alkyl chains and are neutral in nature.
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.
