Now it has been shown that protocell vesicles can assemble from diacylcysteines, which form spontaneously from cysteine and short-chain thioesters. Silica catalyses membrane formation, and protocells formed from diacylcysteine lipids are compatible with ribozyme activity. Christy J. Cho Taeyang An ...
