Fructose Metabolism

Fructose Metabolism

Fructose is an abundant sugar in the human diet. This dietary monosaccharide is present naturally in fruits and vegetables, either as free fructose or as part of the disaccharide sucrose, and as its polymer inulin. Sucrose (table sugar) … Read more

Fatty Acid Synthesis

Fatty Acid Synthesis

Lipogenesis, the synthesis of fatty acids and their esterification to glycerol to form triacylglycerols, which occurs mainly in the liver in humans, with dietary carbohydrate as the major source of … Read more

Uronic Acid Pathway

URONIC ACID PATHWAY

Uronic acids are a class of sugar acids with both carbonyl and carboxylic acid functional groups. They are sugars in which the terminal carbon’s hydroxyl group has been oxidized to a carboxylic acid. Oxidation of the terminal aldehyde instead … Read more

Oxidative Phosphorylation

Oxidative Phosphorylation and ETC

The NADH and FADH2, formed during glycolysis, β-oxidation of fatty acids and the TCA cycle, give up their electrons to reduce molecular O2 to H2O. Electron transfer occurs through a … Read more

Beta-oxidation of Fatty Acid

Beta-oxidation of Fatty Acid

Beta-oxidation is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA. Acetyl-CoA enters the citric acid cycle while NADH and FADH2, which are co-enzymes, are used in … Read more

Enzyme Inhibition

Enzymes are the biological macromolecules, also called as biological catalysts, which speed up the rate of biochemical reactions without undergoing any change. It is a highly selective catalyst that greatly accelerates … Read more
