Forms of cholesterol

Morphology % UC/ EC/ PL Mole % UC/ PL Molar ratio Size
Small droplets 22 / 69 / 9 2.5 100 nm
Lamellar membranes 59 / 17 / 24 2.6 40-200 nm
Cholesterol monohydrate crystals 100 / 0 / 0 -- ~4 μm

UC, unesterified cholesterol; EC, esterified cholesterol; PL, phospholipid Percentages are normalized to the sum of UC, EC, and PL, not total lipid Information sources (Guyton and Klemp, 1996; Kruth, 1997; Small, 1988)
