一般描述

L-岩藻糖是一种在哺乳动物体内发现的天然单糖,是多种N-和O-链聚糖和糖脂的重要组分。

应用

L-(−)-岩藻糖已:
  • 用作凝集素珠结合试验中的非半抗原糖,以研究其对诸如花生凝集素(PNA)和双花扁豆凝集素(DBA)等固定化凝集素结合的影响
  • 用作稀释酶解物的内部标准品,用于分析方法
  • 用于合成岩藻糖基硫苷

生化/生理作用

L-岩藻糖也可用作食品添加剂。它具有抗炎作用。它可抑制皮肤免疫反应和肺泡巨噬细胞启动。L-岩藻糖还可抑制肿瘤生长和肿瘤形成。
L-岩藻糖(6-脱氧-L-半乳糖)用于含有聚糖的岩藻多糖的研究。研究其作为聚糖修饰碳水化合物,其产生IgE抗体识别的抗原位点。L-岩藻糖用作底物以鉴定、区分和表征酶,例如岩藻糖苷酶、I-岩藻糖异构酶和 L-岩藻糖脱氢酶。它可用于研究细胞器、细菌微室,参与植物和藻细胞壁糖的降解。L-岩藻糖还可用作稀有糖鉴定和分析中的参考化合物。

Seaweeds--or marine macroalgae--notably brown seaweeds in the class Phaeophyceae, contain fucoidan. Fucoidan designates a group of certain fucose-containing sulfated polysaccharides (FCSPs) that have a backbone built of (1→3)-linked α-L-fucopyranosyl or of alternating (1→3)- and (1→4)-linked α-L-fucopyranosyl residues, but also include
