How many cholesterol molecules are there for every phospholipid
molecule? Average molecular weight of protein is 50,000, average MW
of phospholipids is 800, and average MW of cholestrol is 386. The
ratio of mass of protein to phospholipids to cholestrol in human
red bloood cells is about 2:1:1. Example of solving for number of
lipids for every protein is shown below
The average molecular weight of protein is 50,000, average molecular weight of phospholipids is 800 and average molecular weight of cholesterol is 386. The ratio of mass of protein to phospholipids to cholesterol in human red blood cells (RBCs) is about 2: 1: 1. Number of lipid molecules (cholesterol + phospholipids) for every molecule of protein can be calculated as follows: Number of lipid molecules = (2/50,000)/(1/800 + 1/386) = 100 Hence, there are 100 molecules of lipids for every protein molecule.
