The membrane phospholipid structures in bacteria and archaea differ. Which one of the following correctly states the differences between the two?
- 1Bacterial membrane phospholipids consist of L-glycerol linked to hydrophobic tails with ether bonds, whereas archaeal membrane phospholipids consist of D-glycerol linked to hydrophobic tails through ester bonds.
- 2Bacterial membrane phospholipids consist of D-glycerol linked to hydrophobic tails with ether bonds, whereas archaeal membrane phospholipids consist of L-glycerol linked to hydrophobic tails through ester bonds.
- 3Bacterial membrane phospholipids consist of L-glycerol linked to hydrophobic tails with ester bonds, whereas archaeal membrane phospholipids consist of D-glycerol linked to hydrophobic tails through ether bonds.
- 4Bacterial membrane phospholipids consist of D-glycerol linked to hydrophobic tails with ester bonds, whereas archaeal membrane phospholipids consist of L-glycerol linked to hydrophobic tails through ether bonds.✓
Correct answer
Bacterial membrane phospholipids consist of D-glycerol linked to hydrophobic tails with ester bonds, whereas archaeal membrane phospholipids consist of L-glycerol linked to hydrophobic tails through ether bonds.
