Most bacterial cell walls contain a macromolecule called peptidoglycan , which human cells do not make or need .

多数细菌的细胞壁含有一种叫做‘肽聚糖’的高分子，人类细胞则不生产和需要这种物质。

Typical bacteria are unicellular prokaryotic organisms that have no organelles except ribosomes , no membrane-enclosed nucleus and have normal peptidoglycan .

典型的细菌是单细胞型的原核生物，除核糖体外无其他细胞器，无核膜，有肽聚糖。

The cell wall is essential for bacterial life because of its tolerance towards the high internal osmotic pressures . An essential constituent of bacterial cell wall is the peptidoglycan .

细菌的细胞壁可保护细胞避免因外界的高渗透压而胀破，对於细菌之生存是必要的，而其细胞壁主要是由肽聚醣所构成。
