Metabolite Identification
Common NameN-Acetyllactosamine
DescriptionN-Acetyllactosamine, also known as galb1-4glcnacb or lacnac, belongs to the class of organic compounds known as acylaminosugars. These are organic compounds containing a sugar linked to a chain through N-acyl group. N-Acetyllactosamine is an extremely weak basic (essentially neutral) compound (based on its pKa). N-Acetyllactosamine exists in all living organisms, ranging from bacteria to humans.

Enzymes

General function:
Involved in alpha-tubulin binding
Specific function:
The Golgi complex form catalyzes the production of lactose in the lactating mammary gland and could also be responsible for the synthesis of complex-type N-linked oligosaccharides in many glycoproteins as well as the carbohydrate moieties of glycolipids.

General function:
Involved in beta-galactoside alpha-2,6-sialyltransferas
Specific function:
Transfers sialic acid from the donor of substrate CMP-sialic acid to galactose containing acceptor substrates. Has alpha-2,6-sialyltransferase activity toward oligosaccharides that have the Gal-beta-1,4-GlcNAc sequence at the non-reducing end of their carbohydrate groups, but it has weak or no activities toward glycoproteins and glycolipids.
