Demonstration of a new mammalian isoleucine catabolic pathway yielding an Rseries of metabolites.

Biochem. J. 160(3) , 417-26, (1976)

1. Normal human urine contains small amounts (less than 4 mg/g of creatinine) of 2-ethylhydracrylic acid, formed, we believe, by a previously undisclosed endogenous catabolic pathway for the oxidation...
