Distribution and nutritive value of the nitrogenous substances in the potato

Abstract

ln a former communication, Chick & Cutting (1943) reported a series of experiments in which the nutritive value of the proteins and other nitrogenous substances of the potato was compared with that of casein and of the proteins in wheat. The criterion adopted was the ability to support growth in weanling rats fed on diets adequate in respect to other essential nutrients, but containing a sub- optimal amount of nitrogen derived solely from the food under test. Under these conditions, in which thenitrogen is the factor limiting growth, the relative rates of growth provide a basis for the comparison of the nutritive values of the mixtures of proteins
