1. Hopanoid
Hopanoid is a chemical component in the cytoplasm ic membranes of many bacteria . Hopanoid is a pentacyclic saturated derivative of mevalonic acid (mevalonic acid is a key intermediate in cholesterol biosynthesis) and is assumed to be functioning in a similar way to sterol s, which serve to stabilize the structure of eukaryotic membranes. While sterols can make up 5-25 percent of the total lipid s of eukaryotic membranes, they are absent from most of the prokaryotic membranes.
