| Asparagine an amino acid containing an amide group. It is effectively aspartic acid with the -OH group on its acidic side chain replaced by a an extra amino group.
Like all amino acids, it has an amino group (-NH2) - blue with 2 white balls - at one end, and a carboxylic acid group (-COOH) - grey, connected to red, and red and white - at the other end. These groups are used to link onto other amino acids by peptide bonds. Between these is the a- (alpha) carbon to which the 'R' group is attached. Its 'R' group is -(CH2)-CO-NH2, a methyl group with an amide group attached. An amide group is a carbonyl group (-C=O) - grey, with red - attached to another amino group - blue with 2 whites - at the other end of the molecule.
