WebDec 26, 2024 · Circulating insulin also affects the synthesis of proteins in a wide variety of tissues. It is therefore an anabolic hormone, promoting the conversion of small molecules in the blood into large molecules inside the cells. Low insulin levels in the blood have the opposite effect by promoting widespread catabolism, especially of reserve body fat. WebOne of the important effects of insulin on intracellular metabolism is its ability to stimulate the synthesis of glycogen in muscle and liver. It does this by promoting a net decrease in the extent of phosphorylation of glycogen synthase, the rate-limiting enzyme in the pathway of glycogen synthesis, which increases its activity.
WebApr 1, 2001 · Treatment of control cultures with 100 nmol/l insulin for 1 h led to an ∼1.9-fold increase in the rate of glycogen synthesis from 134.7 ± 23.45 to 259.8 ± 31.11 pmol · min –1 · mg –1 protein .
