...Sung Do Jang; Robert A. Condrate Abstract The infrared spectra (4000-1200 cm −1 ) are obtained for several Cu-montmoril-lonite-valine complexes that have been prepared at several different pH values. Analysis of the spectra indicates the presence in the interlamellar spaces of both a bidentate...

... with time, but for many amino acids, such as glycine, alanine, valine, leucine, and isoleucine, the rate is very slow. Evidence for conversion of one amino acid into another is provided by observations wherein certain amino acids tend to disappear with time, while new amino acids are created. For example...
