comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولA 1:1 adduct of DL-threonine and arsenic acid.
The title compound, DL-threonine-arsenic acid (1/1), C4H9NO3.H3AsO4, is an unusual adduct containing zwitterionic threonine and neutral arsenic acid molecules. The component species interact by way of N-H...O and O-H...O hydrogen bonds, leading to parallel [001] chains of threonine and arsenic acid molecules which are crosslinked by further O-H...O and N-H...O bonds, resulting in a three-dimens...

Regulation of Lysine and Threonine Synthesis.
Human and monogastric animals cannot synthesize 10 out of the 20 amino acids and therefore need to obtain these from their diet. Among the essential amino acids, lysine and threonine are considered to be exceedingly important in that they are the most limiting essential amino acids in cereal grains, which represent the largest source of food worldwide (Bright and Shewry, 1983). Because of the n...
متن کاملBacterial cell wall synthesis: the effect of threonine depletion.
Our previous studies of Streptococcus faecalis 9790 have shown that the depletion of an essential amino acid from a highly buffered synthetic medium corresponds to the end of the exponential growth phase (log phase) (2, 3). The end of the log phase is followed by further turbidity changes that are characteristic for the particular amino acid studied. The exhaustion of valine is followed by a sl...
