The below mentioned article provides a note on the process of ketogeneis, explained with the help of a suitable diagram. In vertebrates, the acetyl-coenzyme A originating from the β-oxidation can leave the mitochondrion in the form of citrate. However a notable part of this acetyl-coA is used for the synthesis of ketone substances: acetoacetic acid, β-hydroxy-butyric acid and acetone. This [...]
In this article we will discuss about the inhibition of glycolysis by oxygen. Some controls, particularly hormonal, are carried out on glycolysis. We will examine here only the effect of oxygen known as the Pasteur effect because Pasteur was the first scientist to observe that in yeast, glucose was less rapidly consumed in aerobiosis than in anaerobiosis. In other words, [...]
Monosaccharides, and particularly glucose, owe their importance to the fact that their oxidation provides the living organisms with a major part of the energy they require. Furthermore, the carbon atoms of glucose can be found in a large number of compounds (amino acids, fatty acids, sterols, glycerol, etc.). In the study of the metabolism of carbohydrates we will therefore come [...]
