Draw the structure of the glycerophospholipid that contains a stearic acid acyl group, an oleic acid acyl group, and a phosphate bonded to ethanolamine.

Question

Accepted Answer

Welcome back, everyone. Draw the phosphor glyceride that has the following groups attached a palmitic acid, a linoleic acid, a phosphate group bonded to propanol amine. So, first of all, since it is a glyceride, we want to draw the structure of glycerol. And we have to recall that it is a three member chain that contains three hydroxyl groups. But we're going to add three oxygens instead, right? Because we know that each oxygen is going to be bonded to carbonel if we have an acid. So starting with palmitic acid, we have to recall that palmitic acid is a saturated fatty acid with 16 carbons. So it has a form of C 16 to 0. So first of all, we want to draw a carbona followed by 16 carbons. So basically 15 additional carbons. So we have the first one followed by the second one. Then we have 345, 6789 sam 11 1213, 1415 and 16, it is fully saturated. No double bonds are present. The next one is linoleic acid and basically, it has a form of C 18, 2, two. So basically it has 18 carbons and two double bonds and those double bonds start at carbons nine and 12. So how do we draw it? Well, basically, we start with carbonel again and then we want to draw nine carbons. We have the first one, the second one, then we have 345 67 eight. And this is where we have carbon number one. Carbon. Number nine, I'm sorry. Carbon number nine is going to have a double bond. We can label it as carbon number nine. And essentially we want to draw a CIS configuration. So now we're going down. So the two alkyl groups are on the same side of the double bond, we have carbon 11 and then carbon number 12, this is where the next double bond begins. So we're drawing a double bond. And once again, we have, we have it in a cis configuration. So 1213, 1415, 1617 and 18 carbons well done. And now we have a phosphate group. So we essentially have to recall that phosphate is po four right, one of the oxygen atoms is double bonded to phosphorus. And then there are three oxygens that are single bonded. So essentially, we want to draw two oxygen atoms and then we're not yet adding those charges. We see that there's propanol amine and propanol amine essentially has oh two carbons followed by NH two. But when we remove that hydrogen, well, we can essentially proton the amino group and that alcohol part is going to be part of phosphate, right. So essentially we want to take that common oxygen atom draw a two member chain 12, right? In this case, it's actually propanol amine. So my apologies, we should add an additional carbon. Previously, I drew ethanolamine. In this case, it's propanol amine, we need 1 to 3 carbons instead followed by the amino group. So 12 and we followed by an amino group. In this case, it will be pronated and three with a positive charge. And what we notice is that there is still one oxygen that only contains one bond. So this is where we add a negative charge. So we have basically got the required structure. Let's label it as our final answer. And thank you for watching.
