&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Lipopolysaccharides&amp;#039;&amp;#039;&amp;#039; (LPS), also known as &amp;#039;&amp;#039;&amp;#039;lipoglycans&amp;#039;&amp;#039;&amp;#039; and &amp;#039;&amp;#039;&amp;#039;endotoxins&amp;#039;&amp;#039;&amp;#039;, are large molecules consisting of a lipid and a polysaccharide composed of O-antigen, outer core and inner core joined by a covalent bond; they are found in the outer membrane of [[Gram-negative bacteria]], and elicit strong immune responses in animals.&lt;br /&gt;
&lt;br /&gt;
==Structure==&lt;br /&gt;
The term &amp;#039;&amp;#039;lipooligosaccharide&amp;#039;&amp;#039; (&amp;quot;LOS&amp;quot;) is used to refer to a low-molecular-weight form of bacterial lipopolysaccharides.&lt;br /&gt;
&lt;br /&gt;
The [[O antigen]] (also known as O polysaccharide) is attached to the core oligosaccharide, and comprises up to 40 repeating units of a four- or five-sugar residue sequence.&lt;br /&gt;
&lt;br /&gt;
==Function==&lt;br /&gt;
Lipopolysaccharides play an important role in bacterial pathogenicity. They are, for example, essential in the functioning of [[bacterial outer membrane proteins]].&lt;br /&gt;
&lt;br /&gt;
==Medical relevance==&lt;br /&gt;
Lipopolysaccharides are considered pathogen-associated molecular patterns (PAMPs) and can trigger an immune response in animals. They can cause fever, changes in white blood cell counts, and other typical symptoms of infection and inflammation.&lt;br /&gt;
