Structure
part-B Name of the fatty acid bonded to the structure
part-C Classify CHOLINE
part-D What is the net charge for PO4-CHOLINE ?
part-E Is this structure water soluble? Explain briefly
Homework Answers
A.) The structure is of the family of glycerophospholipid. and name of structure is phosphatidylcholine
B.) Myristic acid ( Tetradecanoic acid ) C14:0
C.the phosphate ester link to the right of the phosphorous atom is the amino alcohol choline, HOCH2CH2N+(CH3)3
Lipids of this type are known as either phosphatidylcholines, or lecithins.
D.Net Charge is +1
E. Phosphatidylcholines consist of a water-soluble head (a positively charged (polar) group), linked to two water-insoluble nonpolar tails (by a negatively charged phosphate group). ... Due to its polar nature, the head of a phospholipid is attracted to water (it is hydrophilic). So they Form emulision when dissolved in water.
