    Hasegawa H, Akira K, Shinohara Y, Kasuya Y, Hashimoto T. Kinetics of intramolecular acyl migration of 1beta-O-acyl glucuronides of (R)- and (S)-2-phenylpropionic acids. Biol Pharm Bull. 2001;24:852-5 pubmed
    ..The value of the free energy of activation at 310 K for (R)-1PG (99.67 kJ/mol) was smaller than that of (S)-IPG (101.60kJ/mol), suggesting that (R)-IPG showed thermodynamically higher reactivity in acyl migration than (S)-1PG. ..

    ..77, whereas that in five-sixths-nephrectomized rats was 0.25. The elimination behavior of d-[(2)H(7)]leucine observed in rats suggested that kidney was the principal organ responsible for converting d-leucine to KIC. ..
