Because glycine only has an atom of hydrogen for the side chain, it can form many more unusual bonds angles that other amino acids cannot (See its Ramachandran plot). Because of its uniqueness, any other amino acids mutated in will likely destabilize the protein, and not be selected.
Edit: This is kinda more protein than cell bio
