Amino Acids
It is an amino group, part of the structure of an amino acid that also includes alpha carbon, carboxyl group, hydrogen and an R group side chain. Basic amino group H2N (-NH2) may gain a proton and become -NH3+, an acidic carboxyl group (H3N).
Two functional groups are found in all amino acids. These functional groups are the amino group (-NH2) and the carboxyl group (-COOH). The hydrogen atom of the carboxyl group can be broken off quite easily; this gives amino acids their acidic properties.
An amino group and an R group
an oxygenThe central carbon atom in an amino acid is bonded to an amino functional group, a carboxyl functional group, a side chain, and hydrogen.
Amino acids have 2 functional groups, an a-carboxyl group and an-amino group.

The two amino acids aspartate and glutamate each contain two carboxyl groups.
NH3 is not a carboxyl group.
An amino acid always has an amino group and a carboxyl group. The amine group of one amino acid is capable of forming a peptide bond with the carboxyl group of another amino acid.
An amino acid consists of an amino group, a carboxyl group, a hydrogen group, and a side group (R group) all attached to a central (alpha) carbon.

It is an amino group, part of the structure of an amino acid that also includes alpha carbon, carboxyl group, hydrogen and an R group side chain. Basic amino group H2N (-NH2) may gain a proton and become -NH3+, an acidic carboxyl group (H3N).
Amino acids have a generalised structure consisting of an amino group (-NH2), a carboxyl group (-COOH), and a side chain represented by the letter "R". The side chain can vary among different amino acids, giving them distinct chemical properties. The central carbon atom (alpha carbon) connects the amino group, carboxyl group, and the side chain, forming the backbone of the amino acid.
