—Not yet.— Glycine contains two reactive groups: an amine and a carboxylic acid. Suppose a chemist wants to use the acid but needs the amine to stay out of the way. One solution is protection.
In N-(trifluoroacetyl)glycine, the amino group is temporarily converted into a trifluoroacetamide. The CF3CO- group strongly changes the nitrogen's electronic behavior. Instead of acting like a reactive free amine, the nitrogen becomes much quieter. Now chemistry can happen elsewhere.
