Previous studies (1, 2) have shown that radioactive carbon from uniformly labeled glucose is incorporated in vitro into all of the protein-bound amino acids except proline and threonine by minced 1 day-old mouse brain. Inoculation of such preparations with Theiler’s GD VII mouse encephalomyelitis virus resulted in extensive virus propagation and an increased incorporation of radioactivity into ...

In the present work, 16 genetic code doublets and their cognate amino acids in the genetic code are fitted into a polyhedron model. Based on the structural regularity in nucleobases, and by using a series of common-sense topological approaches to rearranging the Hamiltonian-type graph of the codon map, it is identified that the degeneracy of codons and the internal relation of the 20 amino acid...

Readily available natural α-amino acids are one of nature's most attractive and versatile building blocks in synthesis of natural products and biomolecules. Peptides and N-heterocycles exhibit various biological and pharmaceutical functions. Conjugation of amino acids or peptides with N-heterocycles provides boundless potentiality for screening and discovery of diverse biologically active molec...

securigera securidaca (l.) degen & dorfl grows in different parts of iran. the seeds of the species are used in iranian folk medicine as an anti-diabetic agent. many studies have established hypoglycemic effects of amino acids and in the present investigation, amino acids of securigera securidaca seeds have been evaluated. the ground seeds were extracted using petroleum ether, hot ethanol a...

It is well known that the amino acids occurring in proteins (natural amino acids) are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation. The recent observation ...

In this article, adsorption of some amino acids and their complexation with lanthanum(III) ion on carbon nanotube (MWCNT) by using of three relations Langmuir, Freundlich and Temkin isotherms was investigated. From this relations, Freudlich and Temkin relations predict good equilibrium diagram in isotherm condition. We could compute the theoretical constants by excel software. By considering th...

Correction for ‘Stereo-selective synthesis of non-canonical γ-hydroxy-α-amino acids by enzymatic carbon–carbon bond formation’ Rui Zhang et al. , Catal. Sci. Technol. 2021, 11 7380–7385, https://doi.org/10.1039/D1CY00955A.

As natural plant growth stimulators, amino acids are widely used to improve the yield and quality of crops. Change in enzymes activities of N assimilation (NR, NiR and GS), residual nitrate (NO3-), soluble protein content, and yield of spinach and lettuce plants were investigated under replacing 20% nitrate-N in the nutrient solution by L-glycine and blood meal amino acids. Seeds of the mention...

objective(s) motility plays a major role in pathogenicity of helicobacter pylori, yet there is  scarce data regarding its chemotactic behaviour. the present study was designed to investigate the chemotactic responses of local isolates of h. pylori towards various sugars, amino acids, as well as some other chemical substances. materials and methods chemotaxis was assayed by a modified adler’s me...
