adipsin

An enzyme secreted by fat cells, and also present in the Schwann cells of nerve fibres, that is thought to regulate fat metabolism. It acts on free lipoproteins and is concerned with fat oxidation. Its levels are markedly reduced in genetically obese mice. The full function of adipsin remains unclear.
