THE idea of estimating carnosine colorimetrically is based on the fact that histidine when treated with diazobenzenesulphanilic acid and sodium carbonate gives rise to an intense red colour and this led to an attempt by v. Fiirth and Hryntschak [1914] to evolve a colorimetric estimation of carnosine nitrate.
