Carbohydrate Metabolism

The Carbohydrate Metabolism section includes posts/pages covering the basic biochemistry of biological carbohydrates, as well as the pathways of glycolysis, gluconeogenesis, glycogen metabolism, fructose metabolism, galactose metabolism, the pentose phosphate pathway, the reactions of the pyruvate dehydrogenase complex (PDHc), and the tricarboxylic acid (TCA) cycle

Glycogen Metabolism

Glycogen Metabolism

Last Updated: December 20, 2023 Introduction to Glycogen Metabolism Glycogen is a polymer of glucose residues linked by α-(1,4)- and α-(1,6)-glycosidic bonds. Stores of readily available glucose, to supply the tissues of the body with an oxidizable energy source, are...

Galactose Metabolism

Galactose Metabolism

Last Updated: January 18, 2024 Galactose Metabolism Galactose, which is metabolized from the milk sugar, lactose (a disaccharide of glucose and galactose), enters glycolysis by its conversion to glucose-1-phosphate (G1P). This occurs through a series of steps that is...

Fructose Metabolism

Fructose Metabolism

Last Updated: March 5, 2024 Introduction to Fructose The major natural sources of fructose in the human diet are fruits, honey, and sucrose (a disaccharide of glucose and fructose). Under normal dietary intake the majority of the ingested fructose is metabolized by...
