WebGluconeogenesis refers to synthesis of new glucose from noncarbohydrate precursors, provides glucose when dietary intake is insufficient or absent. It also is essential in the regulation of acid-base balance, amino acid metabolism, and synthesis of carbohydrate derived structural components. Gluconeogenesis occurs in liver and kidneys. Web3. The degree of the inhibition of gluconeogenesis from lactate by ethanol depends on the concentration of lactate and other oxidizable substances, e.g. oleate, in the perfusion medium. 4. Ethanol also inhibits, to different degrees, gluconeogenesis from glycerol, dihydroxyacetone, proline, serine, alanine, fructose and galactose. 5.
