Okay, so when we're talking about r versus s configurations, this has to do with organic chemistry and the way that, like, the weight.
00:11
I say the weight because you think about like priority pretty much, like the priority of in which atoms mean the most.
00:19
So an s configuration goes this way and an r1 goes this way.
00:24
So this is acid.
00:25
This is r.
00:27
So most amino acids are in this s configuration except for l -sistine.
00:34
So l -sistine is in this r configuration.
00:39
And the reason for that is is because all amino acids have four things.
00:49
Number one, they have an amino group, right? and this is the one with the most weight to it.
00:55
So this is priority number one.
00:57
We're going to go in order of priority...
