Detailed explanation-1: -Lipids are molecules that are composed of a hydrophilic head group and a hydrophobic tail.
Detailed explanation-2: -The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails. The tails are usually fatty acids, and they can differ in length (they normally contain between 14 and 24 carbon atoms).
Detailed explanation-3: -1) Lipids may mean fats, waxes, sterols, fat-soluble vitamins, certain glycerides, phospholipids, and more. As such, only some lipids have a hydrophilic head and hydrophobic tail (a phospholipid, for example).
Detailed explanation-4: -Phospholipids are a class of lipids whose molecule has a hydrophilic “head” containing a phosphate group and two hydrophobic “tails” derived from fatty acids, joined by an alcohol residue (usually a glycerol molecule).
