摘要: A fully self-contained model of homochirality is presented that contains the effects both polymerization and dissociation. The dissociation fragments are assumed to replenish substrate from which new monomers can grow undergo polymerization. mean length isotactic polymers found slowly with normalized total number corresponding building blocks. Alternatively, if one assumes themselves polymerize further, then this corresponds a strong source short polymers, an unrealistically average only 3. By contrast, without dissociation, becomes infinitely long.
