Explanation:
Detailed explanation-1: -Why are phospholipids much better than fats and oils at forming cell membranes? A phospholipid contains a phosphate group in the head, where triglyceride does not. Phospholipids contain kinks that allow for more fluidity in the cell membrane while fats and oils are saturated fats that are closely packed together.
Detailed explanation-2: -A phospholipid is made up of two fatty acid tails and a phosphate group head. Fatty acids are long chains that are mostly made up of hydrogen and carbon, while phosphate groups consist of a phosphorus molecule with four oxygen molecules attached.
