N-acetyllactosamine synthase is a galactosyltransferase enzyme.[1][2][3][4][5][6] It is a component of lactose synthase[citation needed] This enzyme modifies the connection between two molecule UDP-galactose and N-actyl-D-glucosamine and generates two different molecules UDP and N-acetyllactosamine as products.[7] The main function of the enzyme is associated with the biosynthesis of glycoproteins and glycolipids in both human and animals.[7] In human, the activity of this enzyme can be found in Golgi apparatus.[7] It is classified under EC 2.4.1.90. The lack of this enzyme leads to glycolysation[7][8][9] which is a serious neurological disease. The nature of the disease causes fluid in the brain, abnormal inflammatory response and abnormal bleeding issues.[7][8][9]
