The enzymatic nutrient pathway in the liver for the production of glucose from noncarbohydrate molecules (amino acids or fatty acids) is called

Gluconeogenesis is a metabolic pathway that results in the generation of glucose from non-carbohydrate molecules, from breakdown of amino acids or fatty acids and from other steps in metabolism that include pyruvate and lactate. This pathway is one of several main mechanisms used by humans and many other animals to maintain blood glucose levels, avoiding low levels of blood glucose.
