Final answer:
The structures of arginine and glycine have a difference in the side chains that make up their structures, but they also have a common feature. Both arginine and glycine are amino acids, which are the building blocks of proteins. They are both involved in protein synthesis and have important roles in the body.
Step-by-step explanation:
The structures of arginine and glycine have a difference in the side chains that make up their structures, but they also have a common feature. Both arginine and glycine are amino acids, which are the building blocks of proteins. They are both involved in protein synthesis and have important roles in the body.
One common feature between arginine and glycine is that they both have a single carbon atom as their backbone, known as the alpha carbon. This alpha carbon is attached to a hydrogen atom in glycine, while in arginine, it is attached to a complex side chain that includes a guanidinium group.
In summary, arginine and glycine are both amino acids involved in protein synthesis, but they differ in their side chains. Arginine has a complex side chain with a guanidinium group, while glycine has a simple hydrogen atom as its side chain.
