The applicability of the spectrophotometric determination of histidine according to Ovadi et al. [(1967) Acta Biochim. Biophys. Acad. Sci. Hung. 2, 455-4581 to a large range of molar ratios of diethylpyrocarbonate (DEP) to histidine requires the use of appropriate differential molar absorptivities d

The role of histidine residues in the chelation of iron at neutral pH by peptides from chicken muscle was investigated to see if it could contribute to the effect of muscle tissue on iron absorption. When ferric iron was chelated by L-histidine at pH 6, the ratio of iron chelated to loss of reactive
The combining of formaldehyde with D-threonine as its sodium salt has been studied by the polariscopic method. A compound of the AF type and one of the AzF3 type have been found. The equilibrium constant of the latter reaction has been calculated. Neither compound could be isolated from solution.
