Question

Which of the 20 standard amino acids can be grouped into the following categories?

a. Contain cyclic/ring structures. b. Sulfur-containing.

Accepted Answer

So this practice problem asks which of the 20 standard amino acids can be grouped into the following categories. The first category is contain a cyclic ring structure, and the second category is sulfur containing. And so whenever you're considering the 20 amino acids, you should think about the demonic that we have. And so those are Gavle imp fat young whippersnappers or F Y. W. Uh, Santa's team craft new quilts and dragons eat nights riding horses. And so we're considering all 20 of these. And first we're gonna work with our first group. So contains cyclic or ring structures. And when you think about cyclic ring structures, you should automatically think about the aromatic amino acids because they all have those benzene rings, which are cyclic structures. And so, for the aromatic amino acids, remember that it's just f Y w fat young whippersnapper. So we'll put all three of these over here under this category. So Final Alan, entire scene and trip to fan all have cyclic ring structures. In addition to that that we need to check some of the other groups just to make sure that there's no other ring structures. And when we go through which you'll notice is that P So P appear for Pro Lean, remember, has a ring structure. It actually has a cyclic our group. And so remember that it's got a backbone and it's Our group does a loop, and it connects back up to the amino group. And so pro Lien is going to be included into this group is well, And in addition to that, down here, what we have is history in, and you can forget that histamine is aligning with a five member ID ring so history and also has a ring so we can add history in into this group is well, and, uh, these are the five amino acids that have cyclic ring structures. So um, that answers part A. Now for part B, it says sulfur containing. And it turns out there's only two amino acids have fall into this group, and these are Mathias me and assisting. So remember that Mutthiah Ning has that thigh Oh, in it so that Theo's referring to the Thile Group or the the sulfur that's in. It's our group and Soma Thiamine has a sulfur atom and insisting, remember is spends quiet time in the Sistine Chapel. So it has an S H group A group. And so both meth I, Inning and Sistine can be categorized into this groups. Um, a thinning as well as Sistine. And these air the Onley two amino acids that are sulfur containing. So this, uh, concludes this practice problem and I'll see you guys in our next video.
