Describe the similarities and differences between triacylglycerols and glycerophospholipids.

Question

Accepted Answer

Hi, everybody. Let's take a look at the next problem here. It says for each statement below, determine whether it accurately describes the similarities or differences between tri aal Glycerol and glycerophosphate. Select all that apply. And then we have four statements that will go through with four multiple choice options that have different combinations of our statements. And we need to select which choice properly list the correct statements. So A is one and three, B is one and four, C is 13 and four and D is 123 and four. So let's take a look at our statements. Statement one says both tri ayl glycerol and glycerophosphate contain a Glycerol backbone. Well, this is correct. We have right there in the name Tri Ayl Glycerol and glycerophosphate. Both of them are based on a Glycerol backbone with then three different groups attached to the three carbons through an ester linkage. So statement one is correct circle that the number of statement two is tri Ayl Glycerol have two fatty acid chains esterified to the Glycerol backbone. While glycerophosphate have three fatty acid chains. Well, this one is incorrect. And again, we have the key in our name here because we have tri ay Glycerol, they have three AC L groups on them. So tri ay Glycerol have three fatty acid chains. While glycophos lipids have two fatty acid chains. And then as we know with that phospholipid in there, they have a phosphate, polar head group on the third carbon. So two fatty acid and then one phosphate. So statement two is incorrect. So we can eliminate choice D which has statement two in there. Then statement three says glycerophosphate include a phosphate group, an additional polar head group while tri ao Glycerol's do not. And this statement is correct. So the glycerophosphate, as we said have this phosphate group with often an amino alcohol group as a polar head group. But try Ao Glycerol's just have the three fatty acid chains. So three is also correct. So we can eliminate choice B which just is one and four. So last of all, we have to look at statement four tri ayl glycerol are primarily involved in energy storage. Whereas glycerophosphate are primarily involved in cell membrane structure. And this is also correct tr ao Glycerol also known as triglycerides are fats. And so we can remember that bats are used in energy storage primarily and then glycerophosphate with their polar head and non polar tail are those molecules that make up that unique structure of the cell membrane. So our correct statements are 13 and four. So choice C while we can go ahead and cross up choice. A so once again of our four statements, the ones that accurately describe similarities or differences between tri ey, Glycerol and glycerophosphate is choice C statements. 13 and four. See you in the next video.
