Hot selling best price antioxidant propyl gallate 121799
Introduction:
Propyl gallate (PG), also known as Bang acid ester c, as a kind of common oil-soluble antioxidants have been widely used in grease and oil food, Fried food, meat food, pollen food, cosmetics, etc. By the gallic acid and normal propyl alcohol under the condition of acid dehydrating agent, made by heating the esterification food additive gallic acid ester c.
Function:
Propyl gallate has been used to probe the cyanideinsensitive alternative oxidase pathway of oxygen uptake in seeds of Orobanche aegyptiaca. A study of cultured lens epithelial cells treated with H2O2 has indicated that propyl gallate dismutates superoxide ion in a catalytic manner and thus mimics superoxide dismutase activity. Propyl gallate (1 mM) has been utilized to probe the activity of plastid oxidase from Arabidopsis thaliana as expressed in tobacco. A report has investigated the utility of propyl gallate with a gold cluster/fluorochrome-labeled antibody probe for immunofluorescence microscopy and immunoelectron microscopy.
