Descrição

Descrição geral

Sinapic acid is a type of phenolic acid. Removal of amino group from phenylalanine, catalysing with enzyme phenylalanine ammonia-lyase forms cinnamic acid. The precursor of hydroxycinnamates is produced after hydroxylation of benzene ring. One of the precursors produced is sinapic acid.

Aplicação

Sinapic acid was suitable as phenolic standard for HPLC analysis in determination of Sinapic acid derivatives in Canola extracts. 10 g/L of sinapinic acid with solvent was suitable as matrix for ultraviolet laser desorption mass spectrometric determination of proteins. It was also suitable to use as matrix for MALDI-TOFMS and MALDI-ion mobility-TOFMS to determine phospholipids in tissue.
