Lipid composition and catalytic properties of sarcoplasmic reticulum from normal and dystrophic chicken muscle

Abstract: The lipid composition of sarcoplasmic reticulum vesicles isolated from the pectoralis muscle of dystrophic chickens (line 413) and of the genetically related line of normal chickens (line 412) were studied. The total lipid content in the dystrophic preparation was increased by 12% when compared to the normal. The increase was restricted to the neutral lipids in the membrane, with a significant increase of 25% in the cholesterol and of 23% in the triacylglycerol contents. Identical phospholipid composition and … Show more

“…Cholesterol is located primarily in the membranes of muscle and several findings have shown increased cholesterol content in membrane fractions of dystrophic muscle fibres [4,[7][8][9]. The altered membrane properties seen in dystrophic tissues may be related directly to such specific changes.…”
