Summary

Aspartic acid changes on being heated without solvents to a not completely uniform substance of anhydride character. This appears to have a structure II different from that assigned to it by earlier investigators. Mild hydrolysis produces a mixture of polyaspartic acids which has been freed by dialysis from constituents of low molecular weight leaving a polypeptide with the approximate molecular weight of 8,200. It is presumed that this polyaspartic acid, differing from the known synthetic α-polyaspartic acid, closely approximates to the β-polyaspartic acid of structure IV.
