生物活性

製品説明	Benzoic acid (FEMA 2131) is a colorless crystalline solid and a simple aromatic carboxylic acid, used as a food preservative.
in vitro	Benzoic acid transports through human skin membranes with the mean maximum absorption rate of 16.54 μg/cm²/h, while the amount in the receptor fluid after 24 hours is 70.6% of the dose applied. The transport of [14C]benzoic acid is significantly inhibited carbonylcyanide p-trifluoromethoxyphenylhydrazone and nigericin, the direct driving force for benzoic acid transport is suggested to be the inwardly directed proton gradient. ^[1] Benzoic acid enters the diet as a natural constituent in plants, with high amounts found in fruits and berries and as a result of the widespread use of monosodium benzoate as a food preservative. Benzoic acid and para-t-butylbenzoate are most potent and acetyl CoA carboxylase (EC 6.4.1.2) appeared to be the target of inhibition. Benzoic acid readily enters the cell to undergo intracellular ionization with a substantial lowering of cytosolic pH and ATP levels under acidic growth conditions. Benzoic acid is oxidized by hydroxy radicals produced by stimulated polymorphonuclear cells oxidize. ^[2] The photometabolism of Benzoic and 4-hydroxybenzoic acids by whole cells is inhibited by the presence of exogenous fatty acids. Benzoic acid enters the anaerobic degradation as follow: initial activation to form benzoyl-Coenzyme A, reduction of the aromatic nucleus--a reaction that has only recently been demonstrated in vitro--and the subsequent degradation of the alicyclic intermediates. ^[3] For Benzoic acid, there is no differences between the mean absorption through human skin and the one rat study, and skin thickness only slightly influences the absorption of Benzoic acid. ^[4]
