N-Acetyllactosamine
C14H25NO11 (383.14275399999997)
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 exists in all living organisms, ranging from bacteria to humans. Structural unit in higher oligosaccharides present in human milk N-Acetyllactosamine (LacNAc), a nitrogen-containing disaccharide, is an important component of various oligosaccharides such as glycoproteins and sialyl Lewis X. N-Acetyllactosamine can be used as the starting material for the synthesis of various oligosaccharides. N-Acetyllactosamine has prebiotic effects[1][2].
Lactosamine
Lactosamine is a disaccharide composed of galactose b1,4-linked to N-acetylglucosamine, and is a common constituent of complex N-linked glycans in metazoans. Unmodified terminal lactosamine, however, is less typical in tissues, since it is often further modified by additional substitutions, such as fucose, sialic acid, or sulfate to form a number of significant receptor and signaling molecules. Lactosamine-containing glycans are also required for proper targeting and maintenance of olfactory axons, and may also function in other sensory regions.(PMID: 17111357). Isolated from human milk
N-acetyllactosamine
C14H25NO11 (383.14275399999997)
A beta-D-galactopyranosyl-(1->4)-N-acetyl-D-glucosamine having beta-configuration at the reducing end anomeric centre. N-Acetyllactosamine (LacNAc), a nitrogen-containing disaccharide, is an important component of various oligosaccharides such as glycoproteins and sialyl Lewis X. N-Acetyllactosamine can be used as the starting material for the synthesis of various oligosaccharides. N-Acetyllactosamine has prebiotic effects[1][2].
