The fatty acids composition of lipids in human adipose tissue and Japanese diet were analysed. It appeared that the fatty acid pattern of human adipose tissue resembled to that of fat in the weals. The total fatty acid composition of the adipose tissue of the patients with cholelithiasis, pregnancy, gastric disease and the normal showed a similar pattern. The percentage of stearic acid in phospholipid fraction of the adipose tissue, in the patients with cholelithiasis, lower than that of the other cases and normal subjects. No significant differences in the fatty acids composition were found between abdominal sub-cutaneous and perirenal adipose tissue.
Effect of several hydrolytic reagents was ex-amined on the proteinaceous amino acid recovery from the residues after the ethanolic extraction of a mushroom, Pleurotus ostreatus. Over 85% of amino acid recovery was achiev-ed by 6 N HCl, 3 N p-toluenesulfonic acid, and 4 N methanesulfonic acid reagents, though the recovery was lower in 3 N mercaptoethanesulfonic acid. The highest recovery was obtained when 1, 500-volume to the sample weight of 6 N HCl was used. The other two reagents, p-tolueneand methane-sulfonic acids, were also applicable to the hydrolysis of mushroom proteins. The proteinaceous amino acid compositions were almost the same in every hydrolyses.
