WebNormally, urea accounts for about 90% of all excreted nitrogen. Amino acid carbon skeletins are reused for the synthesis of other molecules, are a major source of carbon skeletons for the synthesis of glucose (gluconeogenesis) or are oxidized for the production of energy. Gluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates. It is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms. In vertebrates, gluconeogenesis occurs mainly in the liver and, to a lesser extent, in the cortex of the kidneys. It is one of two primary mechanisms – the other being degradation of glycogen (glycogenolysis) – used by humans and many other animal…
