Okay, so we're looking for the structures of a tric acycarboxylic acid, and so this is an example right up here.
00:11
So as you can see, as you can see, we have one carboxylic acid here, one here, and then a third one here.
00:21
So tricarboxylic acid.
00:24
So let's, i have a picture of the citric acid cycle here, and let's go through each structure, and we'll see if any of them are tricarboxylic acid.
00:33
So let's start with oxaloacetate.
00:36
So we see one here and two here, but we do not see a third one.
00:43
So the oxaloacetate is not a tri -carboxylic acid.
00:50
And then we have one here for mallate and two for mallate.
00:55
So again, mallee is out.
01:00
And then we see one...
