Explain the meaning of the words hydrophilic and hydrophobic and state which of those two you believe lipids to be.
A hydrophilic substance is attracted to water and tends to dissolve in water molecules. A hydrophobic substance is repelled by water and usually doesn't dissolve in water molecules. Lipids are hydrophobic.

What is the structure of triglyceride?
A triglyceride structure is made up of three fatty acids attaches to one glycerol molecule. The fatty acid molecule consists of a long chain of carbon and hydrogen atoms with a carboxyl (-COOH) group at one end.
