Alanyl dipeptides such as ala-leu, ala-lys, ala-gly, ala-pro, ala-tyr and ala-phe may be used in physicochemical studies or to evaluate dipeptide separation technologies. Alanyl dipeptides may also be used for studying cell uptake mechanisms, dipeptide metabolism or cell growth supplementation benefits.

The "elution-band relaxation method" has been applied to the analysis of the cis-trans kinetics isomerization of the proline of L-Ala-L-Pro using reversed-phase liquid chromatography. A procedure suitable for cases where neither isomer can be injected separately is described.

The transport characteristics of ceftibuten, a dianionic cephem antibiotic, in rat renal and intestinal brush-border membranes were compared. Ceftibuten transport was mediated by two transport systems in the renal brush-border membrane and by one transport system in the intestinal brush-border

A micro-reactor system with continual spectrophotometric detection has been operated in Sequential Injection lab-on-valve (SI-LOV) mode and applied to enzyme kinetics and inhibition studies, using acetylcholinesterase (AChE) and angiotensin-converting enzyme (ACE) as model systems. With the advantages of automation, real-time

Citrobacter braakii produced an intracellular acid glucose phosphatase (AgpC) which was purified 986 fold to homogeneity with the specific activity of 286 units/mg. AgpC hydrolyzed a wide variety of phosphorylated compounds with high activity for glucose-1-phosphate and glucose-6-phosphate. The optimum

Conformational preferences and prolyl cis-trans isomerizations of the X-Pro motifs (Ac-X-Pro-NHMe, X = Ala and Aib) are explored using the meta-hybrid functional M06-2X and the double-hybrid functional B2PLYP-D with empirical dispersion corrections in the gas phase and in water, where
