Fractional flux rates of Nt-methylhistidine in skin and gastrointestine: the contribution of these tissues to urinary excretion of Nt-methylhistidine in the rat

N Nishizawa et al. Br J Nutr. 1977 Jul.

Abstract

1. Fractional flux rates of Ntau-methylhistidine (3-methylhistidine; Me-His) of skin and gastrointestine were measured by administering [methyl-3H]methionine to rats. 2. The results showed that the contribution of these tissues to urinary excretion of Me-His was at least 16-6%. This means that when fractional catabolic rates of myosin and actin were estimated from urinary excretion of Me-His, the part of Me-His derived from skin and gastrointestine should not be neglected.
