Enzyme activity of superoxide dismutase protomers

the plasma antioxidant activity of superoxide dismutase enzyme in osteoporosis

osteoporosis is a metabolic disease characterized by reduction in bone density and susceptibility to deformity and fracture. some studies show that osteoblasts can create inter-cellular free radicals that lead to cellular death. superoxide dismutase (sod) plays an essential role in cell defense against reactive oxygen metabolites. the purpose of this study was to measure the plasma sod activiti...

Superoxide dismutase Superoxide dismutase

The Effects of Progressive Resistance Training on Malondialdehyde Concentration and Superoxide Dismutase Enzyme Activity in Inactive Elderly Women

Background and Aim: Aging process is associated with increased free radicals and cellular damage. However, resistance training may cause balance of the oxidative and antioxidant system in the elderly. Therefore, the aim of this study was to investigate the effect of eight weeks of progressive resistance training (PRT) on malondialdehyde (MDA) concentration and superoxide dismutase (SOD) enzyme ...

The Cu, Zn Superoxide Dismutase: Not Only a Dismutase Enzyme

The Cu,Zn superoxide dismutase (SOD1) is an ubiquitary cytosolic dimeric carbohydrate free molecule, belonging to a family of isoenzymes involved in the scavenger of superoxide anions. This effect certainly represents the main and well known function ascribed to this enzyme. Here we highlight new aspects of SOD1 physiology that point out some inedited effects of this enzyme in addition to the c...

Superoxide dismutase activity in leukocytes.

Superoxide dismutase activity has been identified in both human neutrophils and rabbit alveolar macrophages by two distinct assay procedures. The enzyme is insensitive to both cyanide and azide and is present in the cytosol of the cell. The identification of this enzyme in phagocytic cells is compatible with the theory that superoxide anion might be involved in the bactericidal activity of the ...
