Inhibition of Growth of G3H Mice by Ethionine and its Alleviation by Methionine or Choline. ∗

Abstract

Summary

0.25%percnt; of ethionine fed together with a complete 30%percnt; casein diet inhibited the growth of weanling C3H mice. The inhibition was alleviated by either choline or methionine, while neither cystine nor homocystine was effective. The observations are discussed in the light of active participation of ethionine or of its ethyl group in metabolic transformations in which methionine and choline methyl groups are normally involved.
