Detailed explanation-1: -The placeholder R is often used as a generic placeholder for alkyl (saturated hydrocarbon) group side chains in chemical structure diagrams.
Detailed explanation-2: -Amino acids differ from each other with respect to their side chains, which are referred to as R groups.
Detailed explanation-3: -The side chain is often abbreviated as an R group and denoted with the letter R for short.
Detailed explanation-4: -This R group, or side chain, gives each amino acid proteins specific characteristics, including size, polarity, and pH.
Detailed explanation-5: -Each of the 20 amino acids has a specific side chain, known as an R group, that is also attached to the carbon. 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.
