Solvation effects on alanine dipeptide: A MP2/cc-pVTZ//MP2/6-31G** study of (Φ, Ψ) energy maps and conformers in the gas phase, ether, and water The effects of solvation on the conformations and energies of alanine dipeptide (AD) have been studied by ab initio calculations up to ...
81 To delineate structure–function relationships, ibuprofen was covalently connected to several dipeptides such as glycine–glycine, glycine–alanine, glycine–serine, glycine–phenylalanine, and glycine–histidine (Figure 9(a)); however, only the glycine–glycine derivative could self-assemble to form ...
No data are available for a large collective. Human serum contains x + s = 240 ± 130 U/l. (n = 24)39, serum of children 160 ± 120 U/l.38(37 °C). Withl-alanyl-alanine, values of 366 U/l.33(mouse plasma) have been found, while forl-leucyl-glycine values of 11.5 ± 0.5...

often the cyclic dipeptide (2,5-diketopiperazine DKP, Fig.1) is formed as the main product. The possible importance of clay minerals in oligomerization and other prebiotic reactions was first suggested by Bernal (1949) and since then has been studied extensively (Ponnamperuma et al.1982; Brack...
