BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Phospholipids consist of two hydrophobic “tails, ” which are fatty acid chains, and one hydrophilic “head, ” which is phosphate group.

Detailed explanation-2: -Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails.

Detailed explanation-3: -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. Unlike triglycerides, which have three fatty acids, phospholipids have two fatty acids that help form a diacylglycerol.

Detailed explanation-4: -Each phospholipid is amphipathic, with two hydrophobic tails and a hydrophilic head. The hydrophobic tails face inward towards one another, and the hydrophilic heads face outwards.

Detailed explanation-5: -The lipid tails face the interior of a biological membrane (Figure 1.3. 1). Phospholipids, glycerolipids, and sphingolipids contain one or more (usually two) fatty acid chains as hydrophobic tails.
