Abstract

The incorporation of [14C]glutamic acid into EDTA-soluble and -insoluble calvaria protein in vitro and [14C]proline into EDTA-insoluble femur protein in vivo was determined in chicks fed inadequate and adequate levels of nonspecific nitrogen (glutamic acid). In each instance, the amount of amino acid incorporated into bone protein was reduced by the low level of nonspecific nitrogen. It was concluded that the high incidence of leg abnormalities observed in chicks fed purified diets containing adequate levels of indispensable amino acids but lacking in total nitrogen might be associated with an inability to form bone matrix protein.
