Abstract
The specificity of various saturated fatty acids, capric, lauric, myristic, palmitic and stearic acids for the esterification of vitamin A by pancreas, liver and intestine was studied. By acetone powder of pancreas, the ester formation of vitamin A was demonstrated with all fatty acids, except capric acid and specificity between fatty acids was not recognized. By acetone powder of liver no significant esterification was observed with all fatty acids. By acetone powder of intestine the esterifying enzyme was not specific toward myristic, palmitic and stearic acids, but with capric and lauric acids the esterification ability was small.
