Synthesis of ketone bodies in liver
WebKetone Bodies Fatty acids undergo -oxidation in the liver mitochondria to generate a high amount of energy and form three compounds, that are known as “ketone bodies”. These ketone bodies are water-soluble and do not require lipoproteins for transportation across the membrane. Ketone bodies are lipid molecules having a carbonyl group WebSynthesis of Ketone Bodies. In a healthy, well-nourished individual, the production of ketone bodies occurs at a relatively low rate. During periods of normal physiological responses to carbohydrate shortages, the liver increases the production of ketone bodies from acetyl-CoA generated from fatty acid oxidation.
