The effects of dietary octopine, which is one of the major extractive
component of marine molluscs, on the level of serum and liver choleste
rol of rats fed with cholesterol-enriched or cholesterol-free diets we
re investigated, Dietary supplementation with 1.5% octopine in a chole
sterol-enriched diet significantly decreased the serum total- and VLDL
+ LDL-cholesterol levels and by contrary increased the serum HDL-chol
esterol level in rats. The same tendency was observed in the rats fed
with 1.5% octopine in a cholesterol-free diet.
