Phytosterols, Phytostanols, and Lipoprotein Metabolism - PMC
Phytosterols and phytostanols are normal bioactive components in plants and in different foods of plant origin. They have similar functions in plants as that of cholesterol in humans. Phytosterols differ from cholesterol by having a different structure in their side chain, whereas phytostanols are 5α-saturated derivatives of phytosterols.
