Web13 feb. 2024 · Sphingomyelin (SM) represents ~85% of all sphingolipids in humans and it is a structural component of cellular membranes that constitutes 10–20 mol% of total plasma membrane lipids [ 6, 7 ]. However, higher concentrations of SM are found in nerve tissue, red blood cells and eye lenses [ 8 ]. WebMembranes 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.
