Chemische Eigenschaften
yellow-brown crystalline powder
Verwenden
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.
Verwenden
4-Hydroxy-3,5-dimethoxycinnamic acid is a commonly used matrix in MALDI mass spectrometry. It is a useful matrix for a wide variety of peptides and proteins. It serves well as a matrix for MALDI due to its ability to absorb laser radiation and to also donate protons (H+) to the analyte of interest.
Definition
ChEBI: A monohydroxycinnamic acid that is cinnamic acid in which the phenyl hydrogens at positions 3, 4, and 5 are replaced by methoxy, hydroxy, and methoxy groups, respectively.
Allgemeine Beschreibung
Sinapic acid is an hydroxycinnamic acid derivative that occurs naturally in Brassicaceae species.
Biochem/physiol Actions
On 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. Sinapic acid exhibits antimicrobial, antioxidant, anticancer, anti-inflammatory, and anti-anxiety activity. Sinapine (sinapoyl choline) has been acknowledged as an acetylcholinesterase inhibitor, making it therapeutically applicable in treatment of various diseases. 4-Vinylsyringol (a decarboxylation product of sinapic acid) is a potent antimutagenic and antioxidative agent, involved in suppressing the induction of inflammatory cytokines and carcinogenesis. Owing to their anti-oxidative activity, these compounds have been considered to be potentially employed in the pharmaceutical industry, cosmetics and food processing.
läuterung methode
