How are archaea different from eubacteria
WebWhile bacteria and eukaryotes have D-glycerol in their membranes, archaeans have L-glycerol in theirs. This is more than a geometric difference. Chemical components of the cell have to be built by enzymes, and the "handedness" ( chirality) of the molecule is determined by the shape of those enzymes.
