PGA is formed in a route of CO, fixation of RuBP catalyzed by RuBPCase, followed by reduction of the PGA by NADH to GAP. This reduction is enhanced in an anionic micellar solution(SDS), in which NADH is distributed in the aqueous and the micellar pseudophases in a given ratio. This micellar bounded NADH reacts to PGA, and in higher micellar concentration than 1.25X 10-2 M, Most of NADH is oxidized to NAD´ by PGA. On the other hand, in the solutions of the positive ionic(CTABr), zwitter ionic(Chaps) and nonionic(Brij and Triton X-100) micelles, the reactions are also enhanced and the concentrations of N ADH reach minima with micellar concentrations. Such minima are typical of micellar catalyzed bimolecular reactions, and the fall in concentrations of the reductant followed by a gradual increase is charataristic of reactions of hydrophobic substrates: that is, the reductions of PGA by NADH are sharply enhanced in a range of the lower micellar concentrations, and NADH amounts in ca. 1.25-2.50 x 10-3M micellar solutions are reached to minima, followed by gradual increases of the reductant concentration.
