Free fatty acids (FFA), a link between obesity and insulin resistance

Web1 jun. 2004 · This mechanism could redirect glucose from muscle to brain during fasting and explain the insulin resistance associated with high-lipid diets and obesity. In overnight-fasted humans, plasma free fatty acid (FFA) concentrations vary between 0.1 and 0.5 mmol/l, primarily due to different rates of lipolysis. WebThe Randle cycle, also known as the glucose fatty-acid cycle, is a metabolic process involving the competition of glucose and fatty acids for substrates. It is theorized to play a role in explaining type 2 diabetes and insulin resistance.. It was named for Philip Randle, who described it in 1963. WebStudies show that obesity or HFD feeding can activate PKCs, which may contribute to insulin resistance by inducing serine or threonine phosphorylation of IR or IRS-1, resulting in impairment of downstream insulin signaling.
