Ginseng extract inhibits lipolysis in rat adipocytes in vitro by activating phosphodiesterase 4.

Elevated concentrations of plasma free fatty acids (FFA) may cause insulin resistance. Inhibition of lipolysis reduces FFA availability and improves insulin sensitivity. Ginseng extract (Panax spp.

Yeast extract stimulates glucose metabolism and inhibits lipolysis in rat adipocytes in vitro.

Foods contain bioactive components that contribute to optimal health. Food-grade yeast may contain components that enhance cellular glucose metabolism. We tested the effect of brewer's yeast (Saccharomyces cerevisiae) extract (YE), in vitro on rat fat cell glucose transport, glucose metabolism to lipid, and lipolysis.
