Breakthrough in Regulating Fat Metabolism

From the 9 December 2011 Science Daily article

Scientists at Warwick Medical School have made an important discovery about the mechanism controlling the body’s ‘fat switch’, shedding new light on our understanding of how proteins regulate appetite control and insulin secretion.

This research, led by Professor Victor Zammit, Head of Metabolic and Vascular Health at Warwick Medical School, found that the enzyme known as ‘Carnitine palmitoyltransferase 1A’ (CPT1) has a switch which is thrown depending on the composition and curvature of its cellular membrane. This is the first time such a mechanism has been described and may possibly be unique, reflecting the importance of this protein to cellular function.

CPT1 is the key protein that regulates fatty acid oxidation in the liver and is critical for metabolism. Its activity determines whether individuals suffer from fatty liver in one extreme or ketosis in the other. Professor Zammit explained: “Knowing that the CPT1 enzyme can switch and what controls it will ultimately lead to a better understanding of why some people appear to have a speedy metabolism and others struggle to curb their appetite….
