Frequently Asked Questions

Which is the best definition of lipopolysaccharide?

Lipopolysaccharide definition is - a large molecule consisting of lipids and sugars joined by chemical bonds.

What does Lipo polysaccharides mean?

/lipo·poly·sac·cha·ride/ (-pol″e-sak´ah-rīd) 1. a molecule in which lipids and polysaccharides are linked. 2. a major component of the cell wall of gram-negative bacteria; lipopolysaccharides are endotoxins and important antigens.

Is lipopolysaccharide toxic?

Lipopolysaccharide is medically important to humans. When free from the bacterium, LPS is toxic. The portion of the LPS that is responsible for the toxicity is the core and lipid A portion (the endotoxin). Endotoxin can produce a fever, decrease in the number of white blood cells, and damage to blood vessels resulting in reduced blood pressure.

What does polysaccharides mean?

Any of a group of polysaccharides in which a lipid constitutes a portion of the molecule, found in the outer cell wall of gram-negative bacteria. THE AMERICAN HERITAGE® DICTIONARY OF THE ENGLISH LANGUAGE, FIFTH EDITION by the Editors of the American Heritage Dictionaries.
