Hydroxycarboxylic acid receptors

Overview

The hydroxycarboxylic acid family of receptors respond to organic acids, including the endogenous hydroxy carboxylic acids 3-hydroxy butyric acid and L-lactic acid, as well as the lipid lowering agents nicotinic... [read more] acid (niacin), acipimox and acifran [1,2,3]. These receptors were provisionally described as nicotinic acid receptors, although nicotinic acid shows submicromolar potency at HCA₂ receptors only and is unlikely to be the natural ligand [2,3].
