Ascorbic acid as a free radical scavenger in porcine and bovine aqueous humour.
AIM To study the antioxidant activity, UV absorption, concentration and stability of ascorbic acid (AA) in porcine and bovine aqueous humour (AH). METHODS Porcine and bovine AH was taken within 5 min after death and frozen at -70 degrees C. The characteristic UV absorption band of AA and the concentration of AA in AH was determined by UV spectrophotometry. The antioxidant activity of AA to se...
متن کاملAction of ascorbic acid as a scavenger of active and stable oxygen radicals.
Free radicals attack lipids, proteins, enzymes, and DNA to cause pathological events and cancer. Ascorbic acid is one of the strongest reductants and radical scavengers and reduces stable oxygen, nitrogen, and thyl radical and acts as a primary defense against aqueous radicals in the blood. When radicals were formed in aqueous suspensions of erythrocytes or low-density lipoprotein (LDL), ascorb...

The oxidative stress causes many diseases in human, therefore antioxidants have a specialposition in the medicinal chemistry. Tyrosol is an important antioxidant with a plenty ofbiological properties. There are many strategies such as clustering single drug units in orderto develop new drugs. The cluster effect can increase drug effects relative to single drug unit.Calixtyrosol is the novel clu...

متن کاملRadical scavenger can scavenge lipid allyl radicals complexed with lipoxygenase at lower oxygen content.
Lipoxygenases have been proposed to be a possible factor that is responsible for the pathology of certain diseases, including ischaemic injury. In the peroxidation process of linoleic acid by lipoxygenase, the E,Z-linoleate allyl radical-lipoxygenase complex seems to be generated as an intermediate. In the present study, we evaluated whether E,Z-linoleate allyl radicals on the enzyme are scaven...
