TWO types of visual pigments have been identified in the retinal rods of vertebrates --rhodopsin (A I) and porphyropsin (A2). Wald (1960) suggested a specific pattern of distribution for these pigments in vertebrates on the basis of their habitat salinity. However, data published in recent years on
## Abstract Oxidation of alcohols by direct hydride transfer to the pyrroloquinoline quinone (PQQ) cofactor of quinoprotein alcohol dehydrogenases has been studied using __ab initio__ quantum mechanical methods. Energies and geometries were calculated at the 6β31G(d,p) level of theory. Comparison o
