Abstract
IT has previously been shown1 that the amount of cytoplasm present in the liver is dependent both on the quality and quantity of the protein of the diet. Liver cytoplasm may be determined either by estimating the sum of the protein, phospholipin and nucleic acid contents of the liver or by estimating the non-glycogen non-lipid liver solids. It was suggested at the time that the determination of liver cytoplasm by means of the non-glycogen non-lipid solids may lend itself to a simple and rapid assessment of the biological value of a protein. Since then, investigations have been in progress in this laboratory with the view of developing a suitable method. The most important results obtained from a large number of tests have already been reported2,3, and a detailed paper is being prepared for publication.
