The amino group is present at one end of the amino acid and is represented by the chemical formula NH3
The region on the amino acid that contains the amino group is called the amino terminal
The remainder group or R Group. An amino acid is constituted by the amine group, the carboxylic acid group, and the side chain (AKA Remainder group). It's the chemistry of the side chain that makes an amino acid unique from the other amino acids.
The basic structure of an amino acid is HXN-CHR-CO2H, where, in the 20 most common biological amino acids, X=hydrogen. The R group attached to the amino acid base is what makes up the difference.
The ionizable part of an amino acid is the amino group, which contains a nitrogen atom with a lone pair of electrons that can act as a proton acceptor or donor. This part of the amino acid molecule can gain or lose a proton, giving it the ability to exist in different ionic forms at different pH levels.
In an amino acid structure, the amino group is typically represented by the -NH2 functional group. It is located at one end of the amino acid molecule, attached to the central carbon atom (the alpha carbon), and is distinct from the carboxyl group (-COOH) found on the opposite end. The amino group is responsible for the basic properties of the amino acid and plays a crucial role in protein synthesis.
Mainly The R Group, but also that there is also the particular positions that give the amino acid molecule its characteristic chemical properties. Another is at the -C-C-N- peptide linkage.

The "R" group
The fourth part of an amino acid is the side chain, also known as the R-group. This is a group of atoms that varies for each amino acid and determines its unique chemical properties.
The acid part of an amino acid is the carboxylic acid group, which consists of a carbon atom double bonded to an oxygen atom and single bonded to a hydroxyl group (–COOH). It is responsible for giving the amino acid its acidic properties.
The side chain, also known as the R-group, is the unique part of an amino acid. It varies among different amino acids and gives each amino acid its distinct chemical properties.
The basic structure of an amino acid is HXN-CHR-CO2H, where, in the 20 most common biological amino acids, X=hydrogen. The R group attached to the amino acid base is what makes up the difference.
The general name for the part of an amino acid that varies among different amino acids is the "side chain" or "R-group". This part of the amino acid structure is responsible for determining the unique chemical properties of each amino acid.
Amino acids are of different types e.g. acidic,basic,neutral, imino ,and sulpher containing etc but all types of amino acids possess two functional groups. These functional groups are amino group and carboxylicgroup. An amino group is chemically NH2 , it is a basic group. Other functional group is carboxylic group which is chemically COOH , it is acidic in nature, Functional group is part of molecule that gives it ,its specific chemical characters.Presence of these groups makes amino acid amphoteric.

The amino group is responsible for the basic properties of the amino acid and plays a crucial role in protein synthesis.
In an amino acid molecule, the part that changes is the side chain, or R group, which varies among different amino acids and determines their unique properties. The parts that remain the same in all amino acids are the central carbon atom (alpha carbon), the amino group (–NH2), the carboxyl group (–COOH), and a hydrogen atom. These consistent components are what classify the molecules as amino acids.
