Appearance of C-14 in Fumarate and Lactate Following the Injection of DL-Methionine-2-C-14.

Abstract
Qualitative data indicate that C14 is incorporated into fumarate and lactate following the intraperitoneal injn. of DL-methionine-2-C14 into mice. Degradation studies indicate that CO2 fixation alone does not explain the conversion of DL-methionine to the above acids.
