The four elements of life, combining to form the amino acid alanine, which is contained, for example, in eggs! Made with an incredibly versatile new model kit (www.realatoms.com), which I am happy to announce has become a real product now. Can you, too, show the correct structure of alanine, the zwitterionic structure, with your model kit?
