The primary structures of human pituitary growth hormone and sheep pituitary lactogenic hormone have been compared with regard to similarities in their sequence. Three homologous segments in each molecule, comprising approximately 45 percent of either peptide chain, have been found. These two proteins have apparently evolved from a common ancestor molecule.
