The development of biochemistry in the 20th century

Abstract

This lecture consists of a short appraisal of some of the main features that have characterized the growth of biochemistry during the course of the 20th century. It dwells on the early impacts of vitalism, the emergence and elucidation of the vitamins, the discovery of coenzymes, the concept of active centres of enzymes, the development of experimental techniques (including the use of isotopes), the genetic code, and on the development of molecular biology and closely allied fields of investigation. It concludes with a consideration of the influence of the study of membranes and of neurochemistry on current biochemical thought.
