Facile Production of D-Histidine by Asymmetric Transformation of L-Histidine

Calixarene Drug deleivery invistegation of Calixarene compounds with conection by histidine L and D stereochemistry

In this research, Quantum-mechanical calculations were performed at the HF method with the 6-31+G*basis set and at the B3LYP method with the 6-31+G* basis set in the gas phase and five solvents such as water, DMSO, methanol, ethanol and dichloromethane at six temperatures. According to these theoretical results of IR, we extracted thermo chemical parameters such as enthalpy (∆H Kcal/mol), Gibbs...

2-Fluoro-l-histidine

The title compound, C(6)H(8)FN(3)O(2), an analog of histidine, shows a reduced side-chain pK(a) (ca 1). The title structure exhibits a shortening of the bond between the proximal ring N atom and the F-substituted ring C atom, indicating an increase in π-bond character due to an inductive effect of fluorine.

The Metabolism of L-and D-histidine by Slices of Liver and Kidney*

Whether oxidative deamination is the favored initial step in the catabolism of histidine, as may be the case with many of the amino acids, is open to question. The supporting evidence of Krebs (1) is less striking with r,-histidine than with most other natural amino acids. Kidney slices yielded somewhat more ammonia in the presence of histidine and oxygen than in the absence of either, and live...
