應用

3′-唾液乳糖是一种化合物,在乙酰神经氨酰(NANA)单元中,在 3 号位连接乳糖的半乳糖单元。在 6′-唾液乳糖中,在 6 号位产生这种连接。3′-唾液酸乳糖和 6′-唾液酸乳糖用于区分和表征病毒(如流感病毒和鼻炎病毒)的结合域,它们能识别 NANA 覆盖的细胞表面受体。3′-唾液乳糖和 6′-唾液乳糖用作测量其在牛奶和初乳等材料中的含量的分析方法中的参考化合物。

Samples of milk from a Bryde's whale and a Sei whale contained 2.7 g/100 mL and 1.7 g/100 mL of hexose, respectively. Both contained lactose as the dominant saccharide along with small amounts of Neu5Ac(alpha2-3)Gal(beta1-4)Glc (3'-N-acetylneuraminyllactose), Neu5Ac(alpha2-6)Gal(beta1-4)Glc (6'-N-acetylneuraminyllactose) and Neu5Ac(alpha2-6)Gal(beta1-4)GlcNAc(beta1-3)Gal(beta1-4)Glc

O-Glycans

O-Linked glycoproteins are usually large proteins with a molecular mass of >200 kDa. Glycosylation generally occurs in high-density clusters and may represent as much as 50-80% of the overall mass.
