内毒素是Ｇ－细菌细胞壁中的脂多糖（Ｌｉｐｏｐｏｌｙｓａｃｃｈａｒｉｄｅ，ＬＰＳ），由亲水性的多糖（Ｏ－特异性多糖、核心多糖）及疏水性的类脂ＬｉｐｉｄＡ构成。其中ＬｉｐｉｄＡ是ＬＰＳ结构中最保守的部分，无种属特异性，是ＬＰＳ的主要生物活性成分。ＬＰＳ在细菌?
Endotoxin is a lipopolysaccharide (LPS) in the G-bacterial cell wall and consists of hydrophilic polysaccharides (O-specific polysaccharides, core polysaccharides) and hydrophobic lipid LipidA. Among them, LipidA is the most conserved part of LPS structure and has no species specificity and is the main bioactive component of LPS. LPS in bacteria?
