B54

Methionine

Barnabas, M.V. and Walker, D.C.

Can. J. Chem., 1991, 69, 1252.

Reaction: CH3SCH2CH2C(H)(NH2) –COOH + Mu ® MuH + ?

Type of reaction: H – atom abstraction

kM = 1.4 x 107 dm3mol-1s-1   

KIE = kM / kH = 1.4 x 107 / 3.5 x 108 = 0.04

kH = 3.5 x 108 dm3mol-1s-1 at pH = 1.0 ie for conjugated acid

Muonium reactions in the micellar systems

kM = 1.4 x 107 dm3mol-1s-1 in the SDDS micelles

from: Barnabas, M.V. and Walker, D.C., Can. J. Chem. 1999, 69, 1252.
