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.

Larval haemolymph of Neobellieria bullata (Insecta, Diptera) is highly toxic to adults of the same species: injection causes instant paralysis to death. Referring to their dramatic effect in adult insects the responsible compounds were designated paralysins. Two paralysins, soluble in

Photodissociation of protonated Tyr, Ala-Tyr, Tyr-Ala (Ala = alanine, Tyr = tyrosine), and their complexes with 18-crown-6-ether (CE) was performed in an electrostatic ion storage ring using a tunable laser system. While the three bare ions all absorb strongly at
The use of two new viscous solvents, sucrose solution and agarose gel, is reported for the first time for giving access to the individual NMR spectra of polar and potentially bioactive compounds in a mixture. Under viscous conditions, the tumbling

The fat body of Sarcophaga peregrina larvae was found to have activity for synthesis of sarcophagine (beta-alanyl-L-tyrosine). This activity was due to a soluble enzyme (sarcophagine synthetase) that requires Mg2+ and ATP as cofactors. The enzyme activity decreased significantly after
A separation selectivity model for capillary electrophoresis enantioseparations of weak bases in the presence of uncharged chiral selectors was described as a function of buffer pH and chiral selector concentration. On the basis of the selectivity at the extreme pH
