Abstract
WE wish to present evidence for the formation of two types of cobalt complexes of proteins and polypeptides in which cobalt is probably bound to the peptide groups. A variety of proteins (for example, gelatin, pepsin, edestin, lysozyme, chymotrypsinogen), as well as tetraglycine and poly-DL-alanine, give the complexes, but most of the work has been carried out with commercial gelatin.
