How are sterols similar to other membrane lipids? How are they different?

Solution

We have to describe how sterols similar to other membrane lipids architectural feature of biological membranes is a double layer of lipids membrane lipids are amphipathi,we have to understand there are three types of lipids.

Glycerophospholipids and sphingolipids contain polar or charged alcohols at their polar ends,the most abundant of these polar lipids in most membranes are the glycerophospholipids, sometimes called phosphoglycerides.

The membranes of halophilic bacteria of ciliated protists and of certain invertebrates also contain high proportions of ether lipids,biochemical and biophysical findings have provided a detailed model of the composition and structure of membranes.physical phase behaviour of lipids and their interactions with membrane proteins.

lipids are used for energy storage principally as triacylglycerol esters and steryl esters in lipid droplets,this fundamental principle of amphipathic lipids is a chemical property that enabled the first cells to segregate their internal constituents from the external environment.Lipids also allow particular proteins in membranes to aggregate, and others to disperse. In addition some lipids function to define membrane domains which recruit proteins from the cytosol that subsequently organize secondary signalling or effector complexes.

Sterols similar to other membrane lipids and how are they different;

Maximum every cells have cells have phospholipids in their membranes bacteria and Eukarya both have membrane phospholipids with fatty acid chains ester linked to\' D\'glycerol, present hypotheses suggest that eukaryotic cells arose from a fusion between an archaeal cell and a bacterial cell.
