It is also available as a flavoring agent, contributing a somewhat sour and astringent component to umami taste. [15], Succinic acid is a precursor to some polyesters and a component of some alkyd resins. Neutral phenylsuccinic acid is partially soluble in water, so HCl was used as a strong acid to protonate the anion. [36][37], Succinate inhibition of prolyl hydroxylases (PHDs) stabilizes the transcription factor hypoxia inducible factor (HIF)1. [6] It is marketed as food additive E363. Stir for 5 min to allow complete protonation. Since our excess is very low, our substance was nowhere near being pure. Transamination and subsequent decarboxylation of alpha-ketoglutarate leads to the formation of GABA. Enantiomeric excess: of (+)-phenylsuccinic acid, To comprehend the conversion of an enantiomer to a di-astereomer, enantiomers are identical while diastereomers are not so they can be created by reacting a mixture of both enantiomers with another chiral molecule.
