D- and L-Alanine were fed to rice cells, the growth stage of which corresponded to the latter half of the logarithmic phase. Although the exogenous D-[1-^<14>C]alanine was readily absorbed by the cells, the radioactivity detected in the cells was rather small. This tendency was more marked in the case of L-[1-^<14>C]alanine feeding. These results indicated that fairly large amount of D- and L-[1-^<14>C]alanine absorbed by the cells were decomposed smoothly; then the radioactive carbon derived from this alanine was excluded from the cells. In the D-[1-^<14>C]alanine feeding, most of the radioactivity detected in the cells was related to the cationic fraction of the cells, and alanine was the only labeled compound in the fraction. On the other hand, in the L-[1-^<14>C]alanine feeding, most of the radioactivity in the cells was related to the ethanol insoluble fraction of the cells. In the acid fraction of the cells, compounds A, B and C were labeled on D-alanine feeding, whereas only compounds A and C were labeled on L-alanine feeding. Based on these results, the metabolic patterns of exogenous D- and L-alanine in the cells are discussed.
