Atkins, Martin Philip;
  • Subject: QD

Vitamin B12 catalyses a variety of important reactions in metabolic pathways. Impairment of vitamin B12 by man leads to deficiency diseases e.g. pernicious anaemia. Many mechanistic possibilities have been suggested to account for the transformation of organic substrate... View more
