For these questions, there are given five answers.

For answer a, where all lipids are glycerides, now this is an incorrect option because we know that lipids consist of several classes of fats, including fatty acids, steroids, as well as triglycerides being one of them.
00:44
So saying that all lipids are triglycerides is an incorrect option, as triglycerib is only a subset of the lip, a subset class of the lipids.
00:59
Now for option b, where all lipids are polar, now if we look at, for instance, the structure of a fatty acid, it consists of the non -polar hydrocarbon as shown here by the ch group as well as a polar functional group.
01:52
Now since the use of fatty acid is made up of largely the hydrocarbon group, this part of the this makes the fatty acid a non -polar molecule.
02:21
Now for option c, where it's hydrophilic, this is similar in its meaning as option b, when it means that the lipid is water -loving, which is incorrect.
02:36
So we know that based on the structure of this fatty acid, as an example, lipids are mainly non -polar or hydrophobic.
02:49
Now for option d, we have all lipids are polymers of fatty acid...
