A major type of lipids found in cell membranes is:
|
|
phospholipids
|
|
|
waxes
|
|
|
glycerol
|
|
|
triglycerides
|
Explanation:
Detailed explanation-1: -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-2: -Phospholipids are major components of the plasma membrane, the outermost layer of animal cells. Like fats, they are composed of fatty acid chains attached to a glycerol backbone.
Detailed explanation-3: -Major types include fats and oils, waxes, phospholipids, and steroids.
Detailed explanation-4: -Phosphoglycerides (also known as glycerophospholipids) are the most abundant phospholipids in cell membranes.
