Gram-positive cell wall 葛兰氏阳性菌细胞壁
Gram-negative cell wall 葛兰氏阴性菌
Profiles of the cell envelope the Gram-positive and Gram-negative bacteria. The Gram-positive wall is a uniformly thick layer external to the plasma membrane. It is composed mainly of peptidoglycan (murein). The Gram-negative wall appears thin and multilayered. It consists of a relatively thin peptidoglycan sheet between the plasma membrane and a phospholipid-lipopolysaccharide outer membrane. The space between the inner (plasma) and outer membranes (wherein the peptidoglycan resides) is called the periplasm.

葛兰氏阴性菌会释放内毒素，内毒素是一种多糖分子，当内毒素被注射入血液时， 就会导致热病。（这些物质的学术术语为“热源”，即产生热量，发热的意思）
Endotoxins are heat stable (boiling for 30 minutes does not destabilize endotoxin沸腾30分钟不能降解内毒素), but certain powerful oxidizing agents such as superoxide, peroxide and hypochlorite, degrade them. 内毒素是热稳定性物

Killed Gram negative bacteria releases endotoxins, which is a lipopolysaccharide molecule that cause fever when injected into the bloodstream. (These substances are termed ”pyrogens” meaning generating heat, fever). Pyrogens have also been linked to more serious reactions when injected into the blood (e.g. lethal septic shock) and are a major concern for every dosage form in contact with the blood stream.杀死
