| Common Name | (+)-KRN-7000 |
|---|
| Description | KRN-7000, also known as alpha-GC (C26) or alpha-galcer, belongs to the class of organic compounds known as glycosphingolipids. These are sphingolipids containing a saccharide moiety glycosidically attached to the sphingoid base. Although saccharide moieties are mostly O-glycosidically linked to the ceramide moiety, other sphingolipids with glycosidic bonds of other types (e.G. S-,C-, or N-type) has been reported. (+)-KRN-7000 is found in Agelas mauritianus and Bacteroides fragilis. KRN-7000 is a moderately basic compound (based on its pKa). |
