Increasing the number of double bonds in the fatty acid chain decreases the melting point of the triacylglycerol.

Here's why:

1. Fatty acids are long chains of carbon atoms, with a carboxyl group at one end. Some of these carbon atoms can be connected by double bonds, creating what's known as unsaturated fatty acids.

2. When there are more double bonds in the fatty acid chain, the fatty acid becomes more unsaturated.

3. Unsaturated fatty acids have a lower melting point than saturated fatty acids. This is because the double bonds introduce kinks into the fatty acid chain, preventing the chains from packing together tightly.

4. Triacylglycerols, which are made up of three fatty acids attached to a glycerol molecule, will therefore also have a lower melting point when they contain more unsaturated fatty acids.

So, the more double bonds in the fatty acid chains of a triacylglycerol, the lower its melting point will be.
