متن کاملQuantitative colorimetric determination of tryptophan.
The methods currently used for the estimation of tryptophan are based on one of the following principles: Reaction with aldehydes in acid solution (1, Z), with glyoxylic acid (3), with mercury salts and nitrous acid (4,5), by determination after isolation from its mercury salt (6)) or by the use of Marshal’s reagent (7). Of the above mentioned methods, those based on aldehyde reactions and on t...
