N-Acetyllactosamine (LacNAc) (also known as CD75) is a nitrogen-containing disaccharide.[1]
The N-acetyllactosamine is a component of many glycoproteins[2] and functions as a carbohydrate antigen that is thought to play roles in normal cellular recognition as well as in malignant transformation and metastasis.[3] It is also found in the structure of human milk oligosaccharides and has prebiotic effects.[4]
