Characteristics of Plasmalogens

BIOCHM-RQ7MPZ

Which of the following statements about features that distinguish plasmalogens from common glycerophospholipids is CORRECT?

Example of a Typical Plasmalogen. Roland1952. "Plasmalogen." Wikipedia. Wikimedia Foundation, 4 Oct. 2010. Web. 24 Feb. 2016.

A

The phosphate head group has an N-linked carbohydrate in plasmalogens, but not in typical phospholipids.

B

The long-chain acyl group attached to C-1 of glycerol is an ether linkage in a plasmalogen but is an ester linkage in typical phospholipids.

C

The phosphate head group must have a O-linked carbohydrate group in plasmalogens, but not in typical phospholipids.

D

The long-chain acyl group attached to C-1 of glycerol is an amide linkage in a plasmalogen but is an ester linkage in typical phospholipids.

E

C-1 and C-2 of the glycerol backbone are connected by a double bond in plasmalogens, but not in other phospholipids.
