deoxycholyl
Deoxycholyl is a chemical moiety derived from deoxycholic acid, a secondary bile acid produced in the intestine and a component of bile. In biochemical naming, deoxycholyl denotes the deoxycholic acid residue when it is linked to amino acids such as glycine or taurine to form conjugates. Common conjugates include glycodeoxycholate and taurodeoxycholate, in which the deoxycholyl skeleton is joined to glycine or taurine, respectively.
Chemically, deoxycholic acid is a 24-carbon sterol with the core cholane structure bearing hydroxyl groups at
Biosynthesis and occurrence: deoxycholic acid is formed in the gut by bacterial 7α-dehydroxylation of cholic acid.
Physiological role and relevance: as a bile acid, the deoxycholyl-containing molecules act as detergents that emulsify
