The calcium palmitate gall-stone

Abstract
Crystallographic studies have recently shown that calcium palmitate is the fourth most abundant crystalline constituent of gall-stones. In a study of the gall-stones from 31 consecutive patients undergoing operation at University College Hospital, London, in 1970, 2 patients were found whose stones contained calcium palmitate as the sole crystalline constituent, and a stone from a third patient had this compound as the major component. Three other patients had small beads of calcium palmitate in stones consisting predominantly of cholesterol. Some points of interest concerning these stone-formers are reported.
