In this problem, we're given two different triglycerides shown with the structures in parts a and b.
00:08
We're asked to determine which of the fatty acids in each triglyceride are saturated.
00:15
In order for the fatty acid to be saturated, it has to have no double bonds.
00:20
It has at least one double bond in its structure, then it's unsaturated.
00:25
So these are triglycerides because they have three carbons in the back.
00:31
Backbone and from here over for each of the three fatty acids these define the fatty acid portion of the structure so in the textbook it's given as a condensed structure and i threw them out here so we can better visualize where the double bonds are if there are any we can see that there's a double bond here and there are two here, anywhere that we see a ch in the structure, there's a double bond.
01:11
So since there are two, since there are double bonds in the last two fatty acids in this first triglyceride, those are both unsaturated...
