The chemical reactions involving pyruvate, 2-oxopropanoate.

generation of precursor metabolites and energy

The formation from simpler components of precursor metabolites, substances from which energy is derived, and the processes involved in the liberation of energy from these substances.

main pathways of carbohydrate metabolism

Catalysis of the reaction: acyl-CoA + glycine = CoA + N-acylglycine.

The formation of glucose from noncarbohydrate precursors, such as pyruvate, amino acids and glycerol.

Catalysis of the reaction: choloyl-CoA + glycine = CoA + glycocholate.

The breakdown of a monosaccharide (generally glucose) into simpler components, including pyruvate.

A modification of the TCA cycle occurring in some plants and microorganisms, in which isocitrate is cleaved to glyoxylate and succinate. Glyoxylate can then react with acetyl-CoA to form malate.

The process by which glucose is oxidized, coupled to NADPH synthesis. Glucose 6-P is oxidized with the formation of carbon dioxide (CO2), ribulose 5-phosphate and reduced NADP; ribulose 5-P then enters a series of reactions interconverting sugar phosphates. The pentose phosphate pathway is a major source of reducing equivalents for biosynthesis reactions and is also important for the conversion of hexoses to pentoses.

A nearly universal metabolic pathway in which the acetyl group of acetyl coenzyme A is effectively oxidized to two C02 and four pairs of electrons are transferred to coenzymes. The acetyl group combines with oxaloacetate to form citrate, which undergoes successive transformations to isocitrate, 2-oxoglutarate, succinyl-CoA, succinate, fumarate, malate, and oxaloacetate again, thus completing the cycle. In eukaryotes the tricarboxylic acid is confined to the mitochondria. See also glyoxylate cycle.

The series of events in which a gravitational stimulus is received and converted into a molecular signal.

The series of events in which a chemical stimulus is received and converted into a molecular signal.
