l-Alanine hydrochloride monohydrate
Colorless crystals of l-alanine hydrochloride monohydrate, C(3)H(8)NO(2) (+)·Cl(-)·H(2)O, were obtained from a powder sample that had been left standing in a refrigerator for a few years. The structure displays several inter-molecular hydrogen bonds: the hydroxyl O atom is involved in a single hydrogen bond to the chloride anion, while the ammonium group forms one hydrogen bond to the chloride ...
متن کاملEffects of L-alanine and L-alanine peptides on the chemotaxis of tetrahymena: evolutionary conclusions.
L-alanine and its peptides (L-Ala-2-6) do not attract or repulse Tetrahymena in a 10(-8) M concentration. In 10(-10) M concentration there is a consistent repellent effect. Twenty four hours after L-alanine or L-alanine-peptides' pretreatment (imprinting) the progeny generation of the cells react differently to the same materials. L-Alanine, L-alanine penta- and hexapeptide in both concentratio...
متن کاملExpression of an L-alanine dehydrogenase gene in Zymomonas mobilis and excretion of L-alanine.
An approach to broaden the product range of the ethanologenic, gram-negative bacterium Zymomonas mobilis by means of genetic engineering is presented. Gene alaD for L-alanine dehydrogenase (EC 1.4.1.1.) from Bacillus sphaericus was cloned and introduced into Z. mobilis. Under the control of the strong promoter of the pyruvate decarboxylase (pdc) gene, the enzyme was expressed up to a specific a...
متن کاملHigh – pressure Raman study of L - alanine crystal
Pressure-dependent Raman scattering studies in the range 0.0 – 32 kbar were carried out in L-alanine in order to investigate its external mode phonon spectra in relation to the phase transitions in the crystal. A careful analysis of the spectra shows that the low-energy Raman modes exhibit variation both in frequency and in intensity and between 26 and 28 kbar it is observed a splitting of a ex...
متن کاملCatalytic Stereoinversion of L-Alanine to Deuterated D-Alanine.
A combination of an achiral pyridoxal analogue and a chiral base has been developed for catalytic deuteration of L-alanine with inversion of stereochemistry to give deuterated D-alanine under mild conditions (neutral pD and 25 °C) without the use of any protecting groups. This system can also be used for catalytic deuteration of D-alanine with retention of stereochemistry to give deuterated D-a...
