Welcome back, everyone. Draw the structure of asparagine with an asterisk marking possible chiral carbon atoms. Let's recall the general structure of an amino acid. First of all, we have to begin with the carboxyl part. So we want to draw a carbonel bonded to O right. And that would be the carboxylic acid part. Then we are introducing an alpha carbon and that alpha carbon is going to be bonded to an amino group NH two. And of course, that exact alpha carbon is going to have an alkyl group R as we can see that specific alpha carbon has three bonds. So we simply want to add a hydrogen atom to it to make sure that we satisfy the octet rule. And in this case, we simply want to replace R with the actual identity of the side chain of asparagine. And that our group or asparagine is simply ch two followed by an A IC O nht. So we have Car Bono and NH two. Now that we have the structure of asparagine, we want to identify the carbon atom that has four different substi and only contains single bonds. So we can exclude the two Carbonis we can exclude CH two because it has two hydrogens. And now we clearly see that there is one chiral center which is the alpha carbon. It has nitrogen as a substituent. It has carbon from carboxyl, it has CH two which is a saturated alky counterpart and it has hydrogen. So since that specific carbon has four different substituents, it is a chiral carbon atom and we can label our final answer. Thank you for watching.
