Inclusion of L-Alanine, L-Arginine, L-Aspargine, L-Serine and Proline into θ-Type Zirconium Phosphate

Ruthenium-Nitrosyl Complexes with Glycine, l-Alanine, l-Valine, l-Proline, d-Proline, l-Serine, l-Threonine, and l-Tyrosine: Synthesis, X-ray Diffraction Structures, Spectroscopic and Electrochemical Properties, and Antiproliferative Activity

The reactions of [Ru(NO)Cl5](2-) with glycine (Gly), L-alanine (L-Ala), L-valine (L-Val), L-proline (L-Pro), D-proline (D-Pro), L-serine (L-Ser), L-threonine (L-Thr), and L-tyrosine (L-Tyr) in n-butanol or n-propanol afforded eight new complexes (1-8) of the general formula [RuCl3(AA-H)(NO)](-), where AA = Gly, L-Ala, L-Val, L-Pro, D-Pro, L-Ser, L-Thr, and L-Tyr, respectively. The compounds wer...

Effect of urea on the optical rotatory dispersion of diketopiperazines of L-serine, L-alanine, L-lysine, L-valine, and L-valylglycine.

A new method for the isolation of L-alanine and L-proline from protein hydrolysates.

The present investigation deals with the development of a convenient method for the isolation of alanine and proline from protein hydrolysates. In this work the authors aim to eliminate some of the objections inherent in the older methods (l-6). No expensive reagents are required for the separation of these amino acids, and high yields of the pure final products are secured. In a recent publica...

And L-serine

T1 ribonuclease digestion of yeast tRNA e r in the presence of seryl tRNA synthetase was used for monitoring the relationship between the substrate binding sites on the synthetase. It was found that (a) ATP displaces the tRNA from the synthetase with an effector affinity constant corresponding to the K for ATP of 10 uM; (b) AMP and a number of nucleoside triphosphates, while influencing the rat...

L-arginine and thrombosis.

To the Editor: Kapostza et al1 reported that the administration of L-arginine (the precursor of nitric oxide synthesis) after surgery resulted in a highly significant reduction in the frequency of embolic signals after carotid endarterectomy in patients who were already being treated with aspirin and heparin. Patients with carotid artery disease usually suffer from coronary atherosclerosis. The...
