N-Acetyl-D-lactosamine, N-乙酰基-D-乳糖胺

A natural structural element in a variety of glycoconjugates. Substrate for galactosidases, fucosyltransferases, and sialyltransferases. Useful as a lectin inhibitory sugar and for characterizing lectins.

N-acetyl-D-Lactosamine is a disaccharide consisting of galactose and N-acetylglucose. It occurs naturally as a structural element in a variety of glycoconjugates. N-acetyl-D-Lactosamine is used to characterize lectins. 2

N-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 soluble (in water) and a very weakly acidic compound (based on its pKa). N-Acetyllactosamine has been found in human epidermis, spleen and intestine tissues. Within the cell, N-acetyllactosamine is primarily located in the cytoplasm. N-Acetyllactosamine can be converted into beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminide.

N-acetyllactosamine is a beta-D-galactopyranosyl-(1->4)-N-acetyl-D-glucosamine having beta-configuration at the reducing end anomeric centre.
