Accession Number | HMDB00781 |
Common_Name | N-Acetylgalactosamine 4-sulphate |
Description | Also known as GalNAc4S, this molecule is a key component of dermatan, keratan and chondroitin sulfate. It is also a substrate for the enzyme N-acteylgalactosamine-4-sulphate transferase. This molecule is found in elevated concentrations in the urine of patients suffering from muchopolysaccharidosis type III, IV and VI. Levels are typically 300-400 times normal values. GalNAc4S is thought to be derived from the action of beta-N-acetylhexosaminidase on sulphated GlcNAc or GalNAc residues at the non-reducing end of keratan sulphate, dermatan sulphate or chondroitin sulphate. |
