Question

multiple choice question
which component of lps anchors the compound in the outer membrane of gram-negative bacteria?

lipid a
nam-nag chains
o antigen
core polysaccharide

Explanation:

Lipopolysaccharide (LPS) in Gram - negative bacteria has three main components: Lipid A, core polysaccharide, and O - antigen. Lipid A is a lipid - based structure that anchors LPS in the outer membrane of Gram - negative bacteria. NAM - NAG chains are part of the peptidoglycan layer, not related to anchoring LPS. The O - antigen and core polysaccharide are more involved in other functions like antigenicity and structural support within the LPS, not the anchoring to the outer membrane.

Answer:

A. Lipid A
