3'-唾液酸乳糖

应用

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。

Description

3′-Sialyllactose is a compound where in the acetylneuraminyl (NANA) unit is connected to the galactosyl unit of lactose at the 3 position. In 6′-sialylactose, this connection is at the 6 position. 3′-Sialyllactose and 6′-Sialyllactose are used to differentiate and characterize binding domains of viruses, such as influenza and rhinitis viruses, that recognize NANA capped cell surface receptors. 3′-Sialyllactose and 6′-sialylactose are used as reference compounds in analytical methods developed to measure their presence in materials such as milk and colostrums.
