Aqueous solutions containing amino acids and peptides: Aqueous solutions containing amino acids and peptides. Part 24. Free energetic and enthalpic coefficients for the interactions of some prolyl and sarcosyl terminally substituted compounds at 25°C.Several substances are used for example 15962-47-7 which is its cas registry number. Blackburn, G. Michael; Lilley, Terence H.; Milburn, Peter J. (Chem. Dep., Univ. Sheffield, Sheffield S3 7HF, UK). J. Chem. Soc., Faraday Trans. 1, 82(9), 2965-76 (English) 1986. CODEN: JCFTAR. ISSN: 0300-9599. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Enthalpies of diln. and osmotic coeffs. were detd. in H2O at 25° for binary and ternary mixts. contg. the a-imino acid amides N-acetyl-L-prolinamide [16395-58-7], N-acetylsarcosinamide [95048-77-4], N-acetyl-N'-methyl-L-prolinamide [19701-85-0], and N-acetyl-N'-methylsarcosinamide [24131-61-1]. The results were analyzed to give the enthalpic and heterotactic interactions. The group additivity approach (Savage, J. J.; Wood, R. H., 1976) was used to represent the data; it has limited use. .

Chiral recognition of enantiomeric peptides in water at 25°C by calorimetry: Chiral recognition of enantiomeric peptides in water at 25°C by calorimetry. Barone, G.; Castronuovo, G.; Elia, V.; Giancola, C. (Dep. Chem., Univ. Naples, Naples 80134, Italy). J. Therm.In this article, certain chemicals are used. Some of their cas registry numbers are 71806-49-0 and 15962-47-7 Anal., 30(6), 1367-74 (English) 1985. CODEN: JTHEA9. ISSN: 0368-4466. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) Section cross-reference(s): 22 The heats of diln. in water of binary and ternary solns. of the 2 enantiomeric forms of N-acetylalaninamide have been measured at 25°. The excess enthalpies, expressed as virial expansion series, permit evaluation of the pairwise self and cross enthalpic coeffs. As for the chiral forms of some monosaccharides, the cross coeff. for the interaction between the D and L forms of N-acetylalaninamide is slightly but significantly different from the corresponding self coeff. A weak, water-mediated chiral recognition can be assumed to exist between pairs of amide mols. .
