應用

6'-唾液酸乳糖是一种化合物，其中乙酰神经氨酸 (NANA) 单元在 6 位与乳糖的半乳糖基单元连接。在 3'-唾液酸乳糖中，该连接位于 3 位。3'-唾液酸乳糖和 6′-唾液酸乳糖用于区分和表征病毒的结合域，如流感病毒和鼻炎病毒，它们识别 NANA 封端细胞表面受体。3'-唾液酸乳糖和 6'-唾液酸乳糖用作分析方法中的引用化合物，用于测定乳汁和初乳等物质中是否存在唾液酸乳糖。

Oxidative stress contributes to the pathogenesis of neurodegenerative diseases. With the aim to find reagents that reduce oxidative stress, a phage display library was screened for peptides mimicking α2,6-sialyllactose (6'-SL), which is known to beneficially influence neural functions.

Review of O-Linked Glycoproteins

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.
