Description
Norhyodeoxycholic acid (NHDCA) is a synthetic bile acid and a derivative of hyodeoxycholic acid (HDCA; ).
1,2 NHDCA is an intermediate in the synthesis of 3β-sulfooxy-7β-hydroxy-24-nor-5-cholen-23-oic acid, which has been used as an internal standard for the quantification of Δ
5-bile acid conjugates that have been identified in patients with Niemann-Pick disease type C1.
