E. J. Neather,Isabelle Rodriguestheir great power of correlating and accounting for chemical phenomena in diverse specific areas including the biochemistry of the essential metallic elements, one of which is chromium. In the first part of this communication, we will discuss briefly the general subject and in the second we will des

Respiration and Gaseous Exchange,the oxygen evolution that occurs in photosystem II.. Several investigations have suggested, on the basis of photochemical experiments, that the manganese is involved in the breakdown of a primary oxidant which is formed in the photolytic splitting of water.. The nature of the primary oxidant and the

E. J. Neather,Isabelle Rodriguess also been studied.. In most cases, it has been found that the oxygen of the amide is the principal coordination site, and the carbonyl oxygen of the amide is a better donor than is the carbonyl oxygen of acetone. This has been attributed to derealization of the nonbonding electron pair on the nitr
