Abstract
The present invention provides a sugar derivative of a biologically active peptide, which derivative has a prolonged duration of action when compared to the non-sugar modified peptide, and contains at least on one of the amino acid units a sugar residue which is attached to an amino group thereof by a coupling other than a direct N-glycosidic bond, and additionally, when it is a condensation product of a carboxyl group containing sugar and a peptide with less than 8 amino acid units, by a coupling other than a direct amide bond.
