EC number: 298-190-5 | CAS number: 93778-52-0
Absorption: Only approximately 30% of the dietary behenic acid was absorbed.
Distribution: The appearance of behenic acid in plasma triacylglycerol fatty acids as a rough measure of absorption suggests that little if any behenic acid was absorbed and distributed intact to the fatty acid pool.
Metabolism: Behenic acid may be hydrolyzed shortly after absorption into shorter-chain saturated fatty acids.
Excretion: Behenic acid was recovered in the faeces.
Only approximately 30 % of the dietary Source substance 2 was absorbed.
No data on the test substance are available. The results from a study of the appearance of behenic acid in lymph samples from rats suggest that only 11 -24 % of dietary behenic acid is absorbed. The results from a study of the fecal content of behenic acid in hamsters suggests that only 19 -29 % of behenic acid is absorbed. In humans, who are known to have a greater capacity for absorbing stearic aicd than do animals, fecal recovery of behenic acid suggests that the mean absorption of behenic aicd is about 30 %. The finding that behenate oil feeding resulted in high concentrations of plasma triacylglycerol myristic, palmitic, and stearic acids suggests that behenic acid may be hydrolysed shortly after absorption into shorter-chain saturated fatty acids. These findings suggest that dietary behenic acid is extensively degraded to cholesterol-raising saturated fatty acids (Cater, N. B., Denke, M. A., Behenic acid is a cholesterol-raising saturated fatty acid in humans, Am J. Clin. Nutr., 2001; 73, p41 -44).
