Right-handed 14-Helix in β3-Peptides from L-Aspartic Acid Monomers

Leptogenesis from Right-handed Neutrino Decays to Right-handed Leptons

We investigate what would be the consequences for leptogenesis of the existence of a charged SU(2)L singlet scalar δ . If such a scalar particle exists it allows the right-handed neutrinos to couple not only to left-handed lepton and Higgs doublets as in ordinary leptogenesis, but also to a right-handed charged lepton and a δ. This provides a new source of leptogenesis which can be successful i...

Metabolism of L-aspartic acid.

Aspartic acid, like glutamic acid, occupies a central position in amino acid metabolism. In most tissues it takes part in the transamination reaction (1). In the liver and the kidney, where all amino acids undergo cleamination, the rate of this process for aspartic acid is second only to glutamic acid (2). For these reasons, one would expect the exchange of amino nitrogen of aspartic acid with ...

Probing right - handed currents in B → K ∗ l + l − transitions

A right handed peptide helix containing a central double D-amino acid segment.

The crystal structure of the 13 residue peptide Boc-Leu-Aib-Val-Ala-Leu-Aib-Val-DAla-DLeu-Aib-Leu-Aib-Val-OMe reveals a continuous helical conformation providing an unambiguous characterization of contiguous D-residues in a right handed peptide helix.

Oxovanadium(IV) complexes of salicyl-L-aspartic acid and salicylglycyl-L-aspartic acid.

The dipeptide and tripeptide analogues salicyl-L-aspartic acid (Sal-L-Asp) and salicylglycyl-L-aspartic acid (SalGly-L-Asp) were synthesized and their protonation and complex formation with V(IV)O2+ were studied in aqueous solution through the use of pH-potentiometry and spectroscopic (UV-Vis, CD and EPR) techniques. The phenolate terminus proved to be a good anchoring site to promote (i) the m...
