Question

PROBLEM 19.12 Draw the structure of a triacylglycerol that fits each description: a. a saturated triacylglycerol formed from three 12-carbon fatty acids b. an unsaturated triacylglycerol that contains three cis double bonds c. a trans triacylglycerol that contains a trans double bond in each hydrocarbon chain​

Answer 1

a. A saturated triacylglycerol formed from three 12-carbon fatty acids would have three identical 12-carbon saturated fatty acids attached to a glycerol backbone.

b. An unsaturated triacylglycerol that contains three cis double bonds would have three different unsaturated fatty acids attached to a glycerol backbone. Each fatty acid would contain a cis double bond.

c. A trans triacylglycerol that contains a trans double bond in each hydrocarbon chain would have three different trans fatty acids attached to a glycerol backbone. Each fatty acid would contain a trans double bond.
