William Jencks proposed the use of these molecules as catalysts. Gerald Edelman and Rodney Porter discovered the structure of these molecules, which can be cleaved into Fc and Fab portions using papain. Milstein and Kohler developed techniques for producing the monoclonal type of these proteins, which are composed of two heavy and two light chains. For 10 points, name these Y-shaped proteins that
