To determine:
The structure of lysine and mark an asterisk (*) next to any chiral carbon centers
Introduction:
Amino acids contain a protonated amine and a carboxylic acid in the form of carboxylate ion. These two functional groups are bonded to a central carbon atom called the alpha-carbon. The protonated amine bonded to this carbon is called alpha-amino group and the carboxylate ion as the alpha carboxylate group. The alpha-carbon is also bonded to a hydrogen atom and a large side chain designated as R, which gives unique identification and characteristics to each amino acids.
b.
Explanation of Solution
Lysine is an essential amino acid. The three letter abbreviation of lysine is “Lys” and the one letter code is “K”. The side chain of lysine contains protonated amine as functional group.

- As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C-C bond as its major product: 1. MgCl ? 2. H₂O* If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. This reaction will not make a product with a new CC bond.
