l-mannose

L-(-)-Mannose ((2R,3R,4S,5S)-2,3,4,5,6-pentahydroxyhexanal) 是一种天然存在的非还原糖，常用作食品添加剂。

α-L-Rhamnose monohydrate (6-deoxy-L-mannose monohydrate) 是植物细胞壁果胶多糖鼠李糖半乳糖醛酸聚糖 1 、鼠李糖半乳糖醛酸聚糖 2 的组分。它也是细菌多糖的组分之一，在致病性方面起重要作用。

alpha-L-Rhamnose (6-Deoxy-L-mannose) 是存在植物和细菌中的一种单糖。Rhamnose- 免疫原连接物能被用于免疫疗法。Rhamnose 能通过胞外途径穿过上皮细胞，能够作为肠吸收的标志。

GDP-β-L-fucose is a metabolite in plant and animal. It used for microbe agglutination assay and agglutination inhibition assay. GDP-β-L-fucose is formed by the oxidation-reduction and epimerization of GDP-R-D-mannose in most organisms.

GDP-α-D-mannose disodium gives a competitive inhibition with respect to GTP (Ki 14.7 μM) and an uncompetitive inhibition with respect to mannose-1-P (Ki 115 μM).GDP-α-D-mannose disodium is the donor substrate for mannosyltransferases and the precursor of
