Are my answers correct?
A membrane lipid is subjected to acid hydrolysis and the reaction products are analyzed. One component has the composition C8H3O2, a second has the composition C1sH3oO2, a third has the composition C3HaO3, a fourth has the composition H3PO, and a fifth has the composition C,H14NO. Which of the following is the correct, general name for this type of membrane lipid? CoenzymeQ O Glycerophospholipicd O Ganglioside O Cholesterol Sphingomyelin Question 13 1 pts A membrane lipid is subjected to acid hydrolysis and the reaction products are analyzed. One component has the composition C18H3602, a second has the composition C1&H30O2;, a third has the composition C3HaO3, a fourth has the composition H3PO, and a fifth has the composition CsH14NO. Which of the following is the most accurate name for this type of membrane lipid? Ganglioside O Phosphatidylcholine O Phosphatidylinositol O Glycerophospholipid Phosphatidylethanolamine OSphingomyelin O Phosphatidylglycerol O PhosphatidylserineExplanation / Answer
12.
Acid hydrolysis of membrane lipid produces component with composition C18H36O2, which is a molecular formula of stearic acid. Another component is C16H30O2, which is a molecular formula of palmitoleic acid. Third component is C3H8O3, which is a molecular formula of glycerol. Fourth component is H3PO4, which is a molecular formula of phosphoric acid. Fifth component is C5H14NO, which is a molecular formula of choline.
Therefore, given membrane lipid contains glycerol with two fatty acids and phosphocholine. Hence, general name of this type of membrane lipid is Glycerophospholipid.

Fourth component is H3PO4, which is a molecular formula of phosphoric acid. Fifth component is C5H14NO, which is a molecular formula of choline.
Therefore, given membrane lipid contains glycerol with two fatty acids and phosphocholine. The general class of this type of phospholipids is Glycerophospholipid. Since, besides fatty acids, the head group is choline. Therefore, more appropriate name is Phosphatidylcholine.
