Answer to Question #198070 in Biochemistry for Paul Hackman

Question

1. Name two major lipids constituents of cell membrane

2. What makes most membrane lipids amphipathic?

3.which organelle in eukaryotic cells is involved in lipids synthesis

4.How are dietary fats transported in blood

5. What metabolic pathway is used by red blood cells for energy?

Answer 1

1. phosphatidylcholine and phosphatidylethanolamine
2. the two hydrophobic "tails" derived from fatty acids, joined by a glycerol molecule
3. Golgi apparatus
4. Triglycerides and cholesteryl esters are transported in the core of plasma lipoproteins. The intestine secretes dietary fat in chylomicrons, lipoproteins that transport triglyceride to tissues for storage. Dietary cholesterol is transported to the liver by chylomicron remnants which are formed from chylomicrons.
5. glycolysis (Embden–Meyerhof–Parnas (EMP) pathway)
