脂多糖(Lipopolysaccharide,LPS)是革兰氏阴性细菌细胞壁外壁的组成成分,主要由脂质和多糖构成。LPS的结构如下图所示: 左面为O抗原 ,中间为核心多糖,右面为类脂A. 脂多糖是一种常见的内毒素(Endotoxin),在体内…
脂多醣(英語: Lipopolysaccharide,缩写: LPS)是由一種脂質和一種多醣組成的大分子,是細菌毒素。 它們由含O- 抗原 、外核、內核組成,均以 共價鍵 連接,存在於細菌 荚膜 中,即 革蘭氏陰性細菌 (如 大腸桿菌 和 沙門氏菌 )細胞膜的最外層。
脂多糖是革兰氏阴性细菌细胞壁外壁的组成成分,是由脂质和多糖构成的物质(糖脂质)。脂多糖的结构如右图: 左面为O抗原 ,中间为核心多糖,右面为类脂A.脂多糖是一种内毒素(Endotoxin),当其作用于人类或动物等其他生物细胞时,就会表现出多种的生物活性。
脂多糖(lipopolysaccharide,LPS)是革兰阴性细菌外膜的主要成分,由类脂A、核心多糖和O-特异性链三部分组成。 核心寡糖在中间连接位于外层具有亲水结构的O-特异性链和位于内层具有疏水性的类脂A。

Lipopolysaccharide, now more commonly known as endotoxin, [1] is a collective term for components of the outermost membrane of the cell envelope of gram-negative bacteria, such as E. coli and Salmonella [2] with a common structural architecture.
One of the most studied bacterial surface molecules is the glycolipid known as lipopolysaccharide (LPS), which is produced by most Gram-negative bacteria. Much of the initial attention LPS received in the early 1900s was owed to its ability to stimulate the immune system, for which the glycolipid was commonly known as endotoxin.
lipopolysaccharide,英语单词,主要用作名词,作名词时译为“[有化] 脂多糖”。
英文: Lipopolysaccharide A conjugated polysaccharide in which the noncarbohydrate part is a lipid. Lipopolysaccharides are a major component of the cell walls of Gram-negative bacteria. 中文: 脂多糖:非糖部分为脂质的共轭多聚糖。脂多糖是革兰氏阴性菌细胞
