1) Based on the composition of fatty acids present in each TAG , predict which TAG (X, Y or Z)has the highest melting point. 2) Based on the composition of fatty acids present in each TAG , predict which TAG (X, Y or Z)you would expect to be a liquid (oil) at room temperature. 3) Based on the composition of fatty acids present in each TAG , predict which TAG (X, Y or Z) you would expect to be solid (fat) at room temperature. 4) Complete hydrogenation of TAG (Y) above would yield a TAG of what fatty acid composition? Enumerate the fatty acid composition with the corresponding percentage. 5) Would the hydrogenation product of TAG (Y) be more like the hydrogenation product of TAG (X) or of TAG (Z)?

Transcribed Image Text:Saturated fatty acids like palmitic and stearic acids are examples of saturated fatty acids.
Oleic and linoleic are examples of unsaturated fatty acids.
When unsaturated fatty acids undergo hydrogenation , unsaturated fatty acids are converted to saturated fatty acids.
From the given data above, answer the following questions below. Give a brief explanation of your answers in one sentence.
1) Based on the composition of fatty acids present in each TAG, predict which TAG (X, Y or Z)has the highest melting point.
