Accepted Answer

All right. Hello everyone. So this question is asking us to provide the one letter and three letter abbreviations for amino acids, glutamate and sine and specify the functional group present in each of their side chains. So up on the screen, we have four different answer options labeled A through D proposing different abbreviations and functional groups for their side chains. Now, just as a quick note, oftentimes when talking about amino acids in situations like scientific literature, it's very common to refer to amino acids by their abbreviations and not their full names. Oftentimes the three letter abbreviation is more intuitive and more descriptive compared to the three letter code. For example, Fenno Allen's three letter code is phe whereas the one letter abbreviation of phenylalanine is the letter F. So once again, most of the time, it's that three letter abbreviation that tends to more easily identify what the amino acid is. But in either case, the one letter abbreviation provides a quick reference point. So first let's start with our beginning amino acid here which is glutamate. Now glutamate, oops Guru Mate's three letter code is simply the first three letters of its name. So that's GLU. On the other hand, the one letter abbreviation is the letter E and I like to remember it as the E at the very end of the word glutamate. So that's GLU and E for the abbreviations of Guam. This is not to be confused with glutamine whose three letter abbreviation is GLN. So just keep that in mind. Now, glutamate is an example of an acidic amino acid because its side chain contains a carboxylic acid group. And the way that I like to remember this is by recalling the fact that the suffix A te and glutamate is often used to refer to the conjugate bases of carboxylic acids. So from acetic acid to acetate, for example, and the conjugate acid of glutamate is glutamic acid. So it's an acidic amino acid. And so moving on now to Siri right, the three letter abbreviation for Siren is once again those first three letters of its name. So that's s er and the good news about sir is that its one letter abbreviation is actually quite intuitive because it's just the letter S. So as for the functional group, that Cine side chain has recall that Cine is a polar amino acid because of the hydroxy group on its side chain. So there you have it based on the information that we just gathered for these two amino acids option A matches correctly with all of the information. So just to re summarize for glutamate, we have the abbreviations E and GLU and the side chain functional group is a carboxylic acid for sine. The abbreviations are S and S er and the side chain functional group is that a hydroxyl group? And so with that being said, thank you so very much for watching and I hope you found this helpful.
