phospholipase was isolated ( in two fractions ) from vipera palestinae venom and it was shown to possess phospholipase a activity ( hydrolyzing diacyl-sn-glycerophosphorylcholines , e.g. , lecithin , in the 2-position ) as well as lysophospholipase ( phospholipase b ) activity ( hydrolyzing 1-monoacyl-sn-glycerophosphorylcholines , e.g. , lysolecithin , yielding free fatty acid and glycerophosphorylcholine ) .
