Abstract
Hypocholesterolemic activities and other properties of three different molecular weight pectin were examined. The low-molecular-weight pectin (Mr≒66, 000) obtained by decomposition of original pectin (Mr≒750, 000) had the properties of low viscosity and high solubility, but it lost hypocholesterolemic activities in rats. On the other hand, the medium-molecular-weight pectin (Mr ≒185, 000) had characteristics of both low viscosity and hypocholesterolemic activities.
