Quizplus · Accepted Answer

Archaeal membrane phospholipids can form covalent bonds with one another, creating a more stable and unique structure compared to eukaryotic membrane phospholipids, which do not form these types of bonds. This is a key difference in their chemical composition and structural organization.
