Lewis

Lewis a trisaccharide (Lewis a) is a significant component of glycan structures on spermatozoa and a major constituent of surface glycans on HL-60 cells [1].

N-((2R,3R,4R,5R)-5,6-Dihydroxy-1-oxo-4-(((2S,3R,4S,5R,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)-3-(((2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)hexan-2-yl)acetamide is a natural product for research related to life sciences. The catalog number is T65274 and the CAS number is 71208-06-5.

Lacto-N-fucopentaose II (LNFP II), a sialyl-Lewis hapten of the human Lewis blood group determinant, acts as a monosialo-ganglioside glycolipid and sialyl derivative, CA 19-9, and is recognized as a molecular tumor marker (TM) for biliopancreatic malignancy [1].

Lacto-N-difucohexaose I (LNDFH I), a connecting agent, may facilitate the attachment of oligosaccharides bearing Lewis b sugar chains to water-insoluble polysaccharides [1].

Lucialdehyde B exhibits potent inhibitory activity against herpes simplex virus. It shows cytotoxic effects on Lewis lung carcinoma (LLC), T-47D, Sarcoma 180, and Meth-A tumor cell lines.
