Question

Complete the sentences describing membrane lipids by moving the names of the lipids to the appropriate targets. Some lipids will be used more than once. Some targets require you to place two or  three lipids. (The second statement uses 3 lipids)

are abundant in the myelin sheath around the axons of some neurons. include two fatty acids joined to glycerol by ester linkages. are made up of a 1,2-diacylglycerol and a polar head group alcohol attached by a phosphodiester bond are common in plant membranes by a glycosidic bond. consist of a sulfonated glucose residue attached to C3 of a 1,2-diacylglycerol include two long-chain hydrocarbons attached at each end to glycerol. do not contain glycerol. can contain phosphate

Answer 1

Concepts and reason

Lipids are organic compounds that are usually insoluble but soluble in nonpolar solvents. The chemical composition of lipids includes hydrogen, carbon, and oxygen. The lipid group includes naturally occurring molecules such as fate, waxes, fay-soluble vitamins, waxes, glycerides etc.

Fundamentals

The term lipid is derived from a Greek word “lipos” which means Fat. Unlike other organic compounds such as proteins, polysaccharides which are made up of small units, lipids are not polymers rather they are small molecules. The main biological function of lipids is storage of fat in adipose tissue, acts as energy reservoir, cell signaling, and lipids also act as structural components of cell membrane. Lipids are also used in cosmetics and food industries as well.

Lipids are broadly defined as hydrophobic or amphiphilic molecules and the amphiphilic nature of the lipids allow them to form vesicles, liposomes or membranes in aqueous environment.

Structural Complexity: Lipids On the basis of structural complexity lipids are classified as simple lipids, compound, and derived lipids.
