This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1913. Excerpt: ... THE LINKING TOGETHER OF AMINO ACIDS. By the action of benzoyl chloride upon the silver salt of glycine, Curtius, in 1881, obtained in addition to the expected hippuric acid, C6H6COCl + H2N. CH2. COOH = HCl + C6H6CO--NH. CH, . COOH, two other acids of higher molecular weight. One of these was hippurylglycine or benzoyl-glycyl-glycine, C6H6. CO--HN. CH2. CO--NH. CHa. COOH, as was proved by the study of its salts, its ethyl ester and amide and by its hydrolysis into hippuric acid and glycine. It was the first definite compound known which contained two amino acid residues combined together. The constitution of the other acid, called the y-acid, could not be determined; it had the formula C10H12N3O4, was soluble with difficulty in water and gave the biuret reaction. It was obtained in larger quantities when hippuric ester was fused with glycine, but under these conditions another compound--benzoyl-bisglycyl-glycine--was formed at the same time, so that in this way a series of compounds resulted, each succeeding member containing a glycyl--NH2. CHa. CO--group more than the preceding one. Further investigations upon the constitution of these compounds were only carried out in 1904 by Curtius and Benrath, who found that the y-acid from the analysis of its silver salt, ester, etc., had the formula C19H24N6O6, and that it was benzoyl-pentaglycyl-glycine, C6H6. CO--(NH. CHa. CO)6--NH. CHa. COOH, its ester being identical with the compound synthesised by Curtius and Wiistenfeld (see below). Two other compounds--hippuryl-glycine and benzoyl-triglycylglycine--were found to be formed by fusing together hippuric ester and glycine, but not the previously isolated benzoyl-bisglycyl-glycine. Longer chains than the six membered y-acid are not believed by Curtius and Benrath ..
