Despite the discrepancies in the contribution of PPP flux to overall myocardial intermediary metabolism, the metabolic rate through the PPP is only a fraction of overall glucose uptake (≈50 nmol/g dry weight per minute versus 5–10 μmol/g dry weight per minute). METABOLISM OF CARBOHYDRATES Most dietary carbohydrates are polymers of hexoses,primarily glucose, galactose and fructose. Even though their breakdown products are more thermodynamically stable, this kinetic stability forms a barrier for biochemical reactions to occur. Virtually all of the principal reactions of the intermediary metabolism of carbohydrates, lipids, amino acids, nucleotides and their derivatives are depicted on metabolic maps. Glycogenesis 2. Intermediary metabolism is traditionally viewed as the large, highly integrated network of reactions that provides cells with metabolic energy, reducing power and biosynthetic intermediates. Metabolic intermediates are molecules which are the precursors or metabolites of biologically significant molecules. Although these intermediates are of relatively minor direct importance to cellular function, they can play important roles in the allosteric regulation of enzymes.
