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 amine (amino) part of an amino acid is the H2N- at the end of the molecule. Amino acids have an acidic part with is -COOH. These parts are the same for all amino acids. They also have a variable group which has 20 different combinations available, this is called the residue (or R group) and are different for different types of amino acid eg. Lysine or serine.
The amino group is the NH2 shown in the image above, the opposite end is the triple bonded nitrogen, and the "R" is the sidegroup that determines which amino acid this is (there are 20 natural amino acids used by living things).
the -NH2 bit
-NH2 or -NHR or -NR2
complicated things
-NH3
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.

no part of ion is part of amino acid
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 is different in different kinds of amino acids. The "R" group can be a number of different molecules that are attached to the alpha carbon.
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 "R" group
There are two ions present in every amino acid. There is a positively charged amino group and a negatively charged carboxyl group.
An acidic acid is something with a pH of less than 7.0. Actually this term is used for Amino acids having carboxylic groups higher than amino groups.
Radical group
the carboxyl functional group
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.
carboxyl group of an amino acidf.franklin.....
Amino acids have both amine and carboxylic acid functional groups and are therefore both an acid and a base at the same time.
