Feeder Pathways for Glycolysis

Description

Many carbohydrates besides Glucose (or D-Glucose) meet their catabolic fate in Glycolysis, after being transformed into one of the Glycolytic intermediates. The most significant are the storage polysaccharides Glycogen and Starch; the disaccharides Maltose, Lactose, Trehalose and Sucrose; and the monosaccharides Fructose (or D-Fructose), Mannose (or D-Mannose) and Galactose (or D-Galactose) (Ref.1). Glycogen in animal tissues and in microorganisms; and Starch in plants, are mobilized for use within the same cell by a phosphorolytic reaction catalyzed by Phosphorylase (that is Glycogen Phosphorylase in animals and in microorganisms or Starch Phosphorylase in plants). These enzymes catalyze an attack by Pi (Inorganic Phosphate) on the (Alpha1-4) glycosidic linkage that joins the last two Glucose residues at a non-reducing end, generating Glucose-1-Phosphate and [...]
