2. An organic molecule that functions as a key intermediate in cellular respiration by binding with acetyl-CoA to initiate the Krebs cycle ; a compound containing four carbon atoms and two carboxyl groups crucial for metabolic processes ; a biochemical agent that links carbohydrate, fat, and protein metabolism within cells
3. A dicarboxylic acid involved in the Krebs cycle that reacts with acetyl-CoA to form citrate, facilitating energy production ; a metabolic intermediate that plays a significant role in gluconeogenesis and amino acid synthesis ; a four-carbon molecule that serves as a substrate in essential pathways of cellular metabolism and energy conversion

Etymology: Oxaloacetate is a chemical compound name built from two shorter names. Its first part, "oxalo-", comes from "oxalic acid," the acid first found in wood sorrel, whose name comes from Latin "oxalis," the plant genus. Its second part, "acetate," comes from "acetic acid," the acid of vinegar, and ultimately from Latin "acetum," meaning "vinegar," itself formed from "acēre," to be sour. The "-ate" ending is the chemist's suffix for a salt or ester of an acid. Put together, the name simply describes the molecule's chemistry: a compound that combines the oxalic and acetic acid frameworks. Its name is a modern technical coinage, formed in the chemical naming tradition from older roots rather than from any ancient usage. It is a plain, descriptive construction, and its parts reveal the molecule's structure.
