analysis of the hydrolysis patterns for all three phospholipases in stacked disks , as compared to those in randomized control preparations , suggests a slightly asymmetrical distribution of phosphatidylcholine ( 40 -- 45 % at the outer face ) and phosphatidylethanolamine ( 55 -- 60 % at the outer face ) and a symmetrical distribution of phosphatidylserine in rod outer segment disk membranes .
