please help me to solve these questions regards lipids....!

1. Identify the type of lipid (wax, fatty acid, phospholipid, triacylglycerol, steroid, etc.) for each of the following: b. a. c. CH3(CH2)24 2. a. Draw the triacylglycerol formed from butanoic acid and glycerol. b. Did this triacylglycerol, with saturated bonds, most likely come from a plant or animal source? c. Draw the specific products of saponification when the triacylglycerol you drew above in (2a) is hydrolyzed and then reacted with NaOH. 3. Explain using your own words and/or diagrams how the structure and properties of phospholipids allows for cell membranes to have a hydrophilic exterior both in- and out- side of the cell, and a hydrophobic interior. 4. a. Label these fatty acids (all contain 16 carbon atoms) in order of increasing melting point (use 1= lowest, 3= highest). Note: a has 0 double bonds, b has 1 double bond, and c has 2 double bonds. b. Explain your reasoning
