Description

Stearic acid is a long-chain saturated fatty acid that can be derived from either animal fats or vegetable oils. Compared to other long-chain saturated fatty acids that are hypercholesterolemic, experimental diets high in stearic acid (9.3-11.8% of energy) do not raise plasma total cholesterol or LDL-cholesterol concentrations but may slightly reduce HDL-cholesterol concentrations.1,2 Stearic acid can be used as a hardening agent for vegetable oils and due to its negligible effect on cholesterol metabolism may be used as an alternative to modification of fatty acids by partial hydrogenation.3,4
