Membranes of the lens of the eye of mammals have two particular characteristics, high concentrations of sphingomyelin, and dihydrosphingomyelin and cholesterol. We have studied the miscibility of cholesterol with both egg sphingomyelin and with dihydrosphingomyelin made by hydrogenation of egg sphingomyelin. At a cholesterol mol fraction of 0.5 and lower, crystallites of cholesterol are not present with either form of sphingomyelin, as observed by differential scanning calorimetry and by (13)C… CONTINUE READING
