The biological significance of certain pyridinium betaines, such as diphosphopyridine nucleotide and triphosphopyridine nucleotide, has been fully recognized. The vital importance of these substances in the life of organisms provided an impetus for extensive research in this field, with the…

The regulation of any fishery depends for its direction upon the knowledge of the biology of the fish involved. As the haddock has been one of the more important marine food fishes even before marine biological investigation was initiated in…

The use of P32 in biological investigation has contributed greatly to the knowledge of phosphorus metabolism. Soon after this isotope became available in the late 1930’s, many investigators studied the absorption, distribution and excretion of radiophosphorus in plants and animals.…

In sharp contrast to the wealth of chemical knowledge of the nature of the lipids of mycobacteria (Anderson 1940, 1942, Siebert 1950) is the scarcity of facts available to indicate the routes by which fats are metabolized by these organisms.…

The bias in the development of biochemistry to which Baldwin (1940) drew attention in 1937 has not been remedied in the last two decades. Despite the tremendous advances in our knowledge of the biochemistry of mammals and unicellular organisms made…

A quarter of a century has elapsed since the first steroid hormone was isolated. Since then, there has been a profound and significant advance in our knowledge of the biogenesis of these steroid hormones and their ultimate fate in the…

Replacement therapy provided the first element of knowledge of the nature of adrenocortical secretion. The earliest view on this secretion assumed the existence of a single adrenocortical hormone, called "cortin" (5}. Attempts were made to extract, isolate and characterize this…
