Draw the condensed structural formula for urea.

All right. Hello everyone. So this question is asking us, which is true about the structure of urea, select all that apply. Now, here we have four different statements labeled one through four, which we'll discuss in greater detail. Later on. In this video, we also have four different entry choices labeled A through D proposing which of the statements are correct. But before we talk about the statements individually, I very quickly just want to talk about urea, right? What does it look like? And where does it come from? Now, urea is a very important product of the urea cycle. So what happens in the urea cycle is that the toxic metabolite ammonium or NH four positive is converted into urea? Now, the reason why this is important is because ammonium is toxic to us, right? So, by converting ammonium into, we have a safer byproduct's used to get rid of or rather excrete excess nitrogen. Not only does this allow us to, to excrete, as I said before, any nitrogenous waste, urea being more water soluble is an easy way to excrete nitrogen without using too much water. And the good news is that urea is actually a very simple molecule because in the center of the structure, we have one carbon, that's a car bottle attaching to two amino groups on either side of it. So here is your real. So now that we have a few different or a few facts here about Uria. To understand the context, let's talk about statement one, it says that Urea contains a car bono group which is a carbon double bound to an oxygen. This is true because it's the car bal group that in part describes or rather explains why Urea is soluble in water. Moving on to statement two, it says that Urea contains two amine groups or NH two. This is also correct because we have two amino groups attaching to the carbonyl carbon. Statement. Three says that Urea contains a hydroxyl group or an oh group. This is incorrect because the oxygen in urea is part of the car bono group, not a hydroxy group. And last but not least it says that urea contains only single bonds between carbon and nitrogen. This is correct because the only double bond present is between carbon and oxygen. And so of the four statements, statements 12 and four are correct, which means that c is our correct answer and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful
