SUMMARY —The effect of starches on utilization of protein and lipid composition in the liver of rats was investigated. The carbohydrates tested were rice starch, corn starch, wheat starch, and arrow root starch. Criteria for evaluation of protein utilization were growth response, digestibility of protein, and availability of lysine. Arrow root starch was inferior to corn starch, rice starch, and wheat starch in effect upon protein utilization. Corn starch and wheat starch were similar in effects on protein utilization. Studies of growth and protein efficiency ratios indicated that rice starch is inferior to corn starch and wheat starch. The distribution of fatty acids in the liver lipid was somewhat different in rats fed arrow root starch from that in rats fed the other three starches. Lysine supplementation did not alter the fatty acid pattern in the liver lipid of rats from that in the unsupplemented group.
