Dansyl chloride or 5-(dimethylamino)naphthalene-1-sulfonyl chloride is a reagent that reacts with primary amino groups in both aliphatic and aromatic amines to produce stable blue- or blue-green–fluorescent sulfonamide adducts. It can also be made to react with secondary amines.
Amino acids with the structure NH + 3 −CXY−CXY−CO − 2, such as β-alanine, a component of carnosine and a few other peptides, are β-amino acids. Ones with the structure NH + 3 −CXY−CXY−CXY−CO − 2 are γ-amino acids, and so on, where X and Y are two substituents (one of which is normally H). [7]
Serine (symbol Ser or S) [3] [4] is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated − NH +3 form under biological conditions), a carboxyl group (which is in the deprotonated − COO −
