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.
Small intestinal dipeptidases (substrate: glycyl-L-leucine, L-methionyl-L-methionine, and L-alanyl-L-proline) were determined in uraemic and sham-operated rats given normal protein diet (24%), low protein diet (6%), and total parenteral nutrition for 10-14 days. Disaccharidases (substrate: maltose, sucrose, trehalose, and lactose) were measured

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
Diketopiperazine formation from the N-terminal residues of a peptide chain is accelerated by aprotic dipolar protophobic solvents and catalyzed in organic solvents by alkylammonium carboxylate salts. The t1/2 for the first-order reaction of H-Ala-Pro-NH2 x TFA falls from 20 d

Two forms of prolidase can be separated for all the human cells and tissues examined by DEAE-cellulose column chromatography or batch methods. Serum had a very low prolidase activity eluting as a single peak prior to tissue peak I prolidase.
