It was observed that pyruvic acid and lactic acid formed in the muscle during glycolysis can be reconverted into glucose (or glycogen) when energy is available (in aerobiosis) and one could wonder whether this neoglucogenesis (or gluconeogenesis, or neoglycogenesis) follows — in the reverse direction — the glycolytic path. In fact, among the reactions leading from glucose to pyruvic acid [...]
In this article we will discuss about the substances that liberate one or more monosaccharides on hydrolysis. The Oligo- and Polysaccharides: Holosides therefore consist exclusively of monosaccharides. Depending on the number of molecules of monosaccharides liberated during hydrolysis there are disaccharides, trisaccharides, etc. We will study particularly two groups of compounds: the disaccharides and the polysaccharides. 1. Disaccharides: There are [...]
In this article we will discuss about the pentose phosphates cycle, explained with the help of suitable diagrams. This series of reactions enables the cells to metabolize glucose-6-℗ without using the glycolytic pathways; it is therefore also called "hexosemonophosphate shunt", or "phosphogluconate pathway" (after the name of one of the intermediates of the cycle), or "Dickens-Horecker pathway" (in view of [...]
