Lipopolysaccharide - Wikipedia
Lipopolysaccharide, now more commonly known as endotoxin, [1] is a collective term for components of the outermost membrane of cell envelope of gram-negative bacteria, such as E. coli and Salmonella [2] with a common structural architecture.
Endotoxin | Gram-negative, Lipopolysaccharide, Immune …
endotoxin, toxic substance bound to the bacterial cell wall and released when the bacterium ruptures or disintegrates. Endotoxins consist of lipopolysaccharide and lipoprotein complexes.
Endotoxin - an overview | ScienceDirect Topics
An endotoxin is a complex lipopolysaccharide found in the outer cell wall of gram-negative bacteria, consisting of three main regions: O-specific antigen, core polysaccharide, and lipid A. It is responsible for toxic effects such as fever, multi-organ failure, septic shock, and sepsis.
Bacterial endotoxins: biological properties and mechanisms of action
Endotoxins (lipopolysaccharides, LPS) are agents of pathogenicity of Gram-negative bacteria, implicated in the development of Gram-negative shock. Endotoxin reacts with lipopolysaccharide-sensitive cells producing endogenous mediators such as tumour necrosis factor alpha (TNFα).
Understanding Endotoxin Structure and Release Mechanisms
2024年10月10日 · Endotoxins, primarily found in the outer membrane of Gram-negative bacteria, are potent biological molecules with significant implications for human health and disease. Their presence can trigger strong immune responses, leading to conditions such as sepsis if not properly managed.
Endotoxin - an overview | ScienceDirect Topics
Endotoxin is a major component of the outer leaflet of the outer membrane of Gram-negative bacteria and is composed of carbohydrates, fatty acids, phosphates, and associated metal ions. Endotoxin is also known as lipopolysaccharide (LPS) and varies in its carbohydrate and lipid composition between bacterial strains and species.
Exotoxins vs. Endotoxins: Key Differences and Their Effects
2024年7月22日 · Exotoxins are typically proteins, often with a complex tertiary structure that allows them to interact specifically with host cell receptors. This specificity is a hallmark of their function, enabling them to target particular cell types and disrupt normal cellular processes.
Endotoxin Vs Exotoxin Definitions, Examples and Differences
Endotoxins - Definition. Discovered in the late 19th century, endotoxins are potentially toxic complex compounds commonly produced by Gram-negative bacteria. Also known as lipopolysaccharides (LPS), endotoxins are some of the most common pyrogens (substances with the potential to induce fever).
Differences Between Exotoxins and Endotoxins
2022年8月10日 · Some of the differences between Exotoxins and Endotoxins are as follows: S.N. Exotoxins. Endotoxins. 1. Excreted by organisms, living cell. Integral part of cell wall. 2. Found in both Gram positive and Gram Negative bacteria.
Endotoxins: Structure, Function and Recognition | SpringerLink
Endotoxins are potentially toxic compounds produced by Gram-negative bacteria including some pathogens. Unlike exotoxins, which are secreted in soluble form by live bacteria, endotoxins are comprised of structural components of bacteria.
