Abstract: 

Human erythrocyte glutathione reductase (GR) is a homodimeric flavoenzyme of 105 kDa (1, 2). In vivo GR is not fully saturated with its prosthetic group FAD but the inactive apoenzyme can be completed in vitro according to the equation: apoGR + FAD —holoGR. This is the hypothetical basis for the determination of the erythrocyte glutathione reductase activation coefficient (EGRAC) which is defined as the ratio of FAD-stimulated to unstimulated activity of erythrocytic glutathione reductase (3). The activation coefficient is a reliable index for riboflavin deficiency in man (1). The multifacetted medical aspects, including interference with embryonic development and impaired protection from noxious chemicals, of this widespread hypovitaminosis have been reviewed comprehensively (1,4).
