THE AMINO ACID CONTENT OF SOME SCLEROPROTEINS

Abstract

Knowledge concerning the amino acid content of the scleroproteins is far from complete.The summary tables of Block and Bolling (l), Cohn and Edsall (2), Schmidt (3), and Hawk et al. ( 4) offer the best available data, but there is much disagreement.Lindley (5) and Geiger (6) have recently reported on the constitution of wool.We are reporting on the content of fourteen amino acids in seven scleroproteins.In some instances, our values differ substantially from reports in the literature.In other instances, the content of certain amino acids is reported for the first time.EXPERIMENTAL Methods
