what is pyruvic acid in biology

Start studying biology test 2. It is the final product of glycolysis and is converted into acetyl coenzyme A, which is required for the Krebs cycle. Biology, 22.06.2019 01:00. Stock solution has 100 mg sodium pyruvate in 100 ml saturated (NH 4) 2 SO 4.-M. Smith. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy in one of two ways. Therefore, it unites several key metabolic processes. In thiamine deficiency, its oxidation is retarded and it accumulates in the tissues, especially in nervous structures. It ionizes to give a hydrogen ion and an anion, termed pyruvate. The process is energetically wasteful because so much free energy remains in the lactic acid molecule. If insufficient oxygen is available, the acid is broken down anaerobically, creating lactate in animals and ethanol in plants and microorganisms. It derives from a propionic acid. Pyruvate is also a popular supplement, primarily used to boost weight loss. n. A colorless organic liquid, C3H4O3, formed as an intermediate in carbohydrate metabolism and fermentation and as an end product in glycolysis.

Pyruvic acid supplies energy to living cells through the citric acid cycle (also known as the Krebs cycle) when oxygen is present (aerobic respiration); when oxygen is lacking, it ferments to produce lactic acid. Pyruvate is essential to many metabolic pathways required by living organisms and is represented chemically as C 3 H 3 O 3. It is a conjugate acid of a pyruvate.
