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 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...
Propyl gallate (also known as propyl 3, 4, 5-trihydroxybenoate) is a kind of ester formed through the condensation of gallic acid and propanol. It appears as a fine white to creamy-white crystalline powder. It has long been used as a kind of antioxidants to be supplied to foods especially animal fats and vegetable oil, being especially effective with polyunsaturated fats. Propyl gallate, as an anti-oxidant, can protect the food and oils from the attack and oxygen free radicals, having an effect similar to the superoxide dismutase. It can also be applied to ethers, emulsion, waxes, and transformer oil as the antioxidants..
Propyl gallate is used to protect oils and fats in products from oxidation.
Propyl gallate is used in foods, cosmetics, hair products, adhesives, and lubricants.
Propyl gallate is used as a triplet state quencher and an antioxidant in fluorescence microscopy...
