Accepted Answer

All right. Hello everyone. So this question is asking to determine whether glycerine Trister, a lipid is made up of the following components. Option A says phosphate and amino alcohol B says Glycerol and fatty acid, C says fingaz and steroid nucleus D says phosphate, amino alcohol and fingaz. So first and foremost, what type of molecule is Glycerol Trister in case you're not already familiar with it? Well, based on the name, right? Glycerol. Trister is an example of a tri ay glycerol. And the reason we know that I actually spelled Glycerol wrong one second. But in any, in any case, the reason we know that is because of the first word Glycerol sounding a lot like Glycerol. And the second phrase, tri rate is giving you information about the tri ay groups or in other words, the three ay groups. So what is the basic structure of a given tri ao Glycerol? Well, the first component is the backbone, which is Glycerol. Now, Glycerol, if you recall is a three carbon chain where each carbon has an alcohol group. In other words, each carbon has a hydroxy group. So then from each hydroxy group of the carbons in Glycerol, we have an ester linkage between the backbone and the fatty acid chains that are branching off of that backbone. So from each carbon of Glycerol, we have one oxygen right from the hydroxy group. And then from there, we have the car bono of the A L side chains and then the side chains themselves have a longer carbon chain attached to them. So I'm just going to abbreviate them as an art group. So basically, these acyl groups began as carboxylic acids. Those carboxylic acids underwent an aeration reaction with the hydroxyl groups of glycerol to create this ester linkage that holds both components together. So to summarize our only components, here are glycerol and fatty acid chains. We don't have a phosphate group, we don't have amino alcohol and we don't have Singa or a steroid nucleus. So our answer is going to be option B in the multiple choice B as in boy and there you have it. So with that being said, thank you so very much for watching. And I hope you found this helpful.
