Hyodesoxycholic Acid (HDCA)
CAS NO.:83-49-8
Standard:In-house standard
Test method:HPLC
Assay :≥98%
Formula:C24H40O4
Molecular Weight: 392.58
Description:White or off-white powder,easily soluble in ethanol,almost insoluble in water.
Function
Hyodeoxycholic acid, also known as 3α,6α-Dihydroxy-5β-cholan-24-oic acid or HDCA, is asecondary bile acid, one of the metabolic byproducts of intestinal bacteria. It differs from deoxycholic acid in that the 6α-hydroxyl is in the 12 position in the former. The 6α-hydroxyl group makes HDCA ahydrophilic acid, aproperty it shares with hyocholic acid. HDCA is present in mammalian species in different proportions. It is the main acid constituent of hog bile, and for this reason it was used industrially as precursor for steroid synthesis before total synthesis became practical.
