Abstract

1. The structure of the carbohydrate component of the glycopeptide isolated from the proteolytic digest of ovalbumin has been investigated by chemical and enzymic methods. 2. The results are consistent with the presence of a single carbohydrate prosthetic group, linked through its reducing end group to the peptide chain. 3. Further, all the 2-amino-2-deoxy-d-glucose units appear to be in the N-acylated form, the phenolic hydroxyl group of tyrosine is free and the omega-carboxyl group of aspartic acid is substituted. 4. The carbohydrate component has a branched-chain structure, the two non-reducing ends being terminated by a d-mannopyranosyl and a 2-acetamido-2-deoxy-d-glucopyranosyl residue respectively. 5. The terminal d-mannopyranosyl unit is probably linked through at least one other d-mannopyranosyl residue to the remainder of the carbohydrate.
