Lipid Metabolism

Beta oxidation is the major pathway for catabolism of fatty acids in mitochondria of cell, in which two carbons are successively removed from the carboxyl end of fatty acyl CoA producing acetyl CoA, NADH, and FADH2. The fatty acid is broken between alpha(2) and beta(2) carbon atoms – hence the name beta oxidation. It is an aerobic process requiring oxygen. ...

Fatty acid is an aliphatic carboxylic acid made up of a hydrocarbon chain with a terminal carboxyl group. Fatty acids are usually derived from fats (triglycerides). Fatty acids are important sources of fuel in the body because, when metabolized, they generate large amounts of energy. Heart muscle prefers mostly fatty acids as a source of energy. When fatty acids are ...

Lipids constitute about 15-20% of the body weight. Lipids are a major source of energy for our body. Lipid metabolism is concerned mainly with the fatty acid and cholesterol. The main source of fatty acids is dietary lipids. In the first phase of fatty acid metabolism, fatty acids are oxidized to acetyl CoA by the process of β-oxidation or esterified ...
