Dissociation Constants of Hexosephosphoric Acids.

Experimental Biology and Medicine, 1927
Hexosediphosphoric acid from yeast and hexosemonophosphoric acid from muscle (lactacidogen) were kindly made available from preparations by Professor Embden. Electrometric titration showed both stronger than pure phosphoric acid in the region of the first and, more conspicuously, in that of the second dissociation constant.

Potentiometric investigation of acid-base equilibria of two newv pyrimidine derivatives in various methanol–water media [PDF]

Journal of the Serbian Chemical Society, 2006
The acid-base properties of 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-one (L1) and 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-thione (L2) were investigated potentiometrically at an ionic strength of 0.10M(LiCl) in 19.8, 33.6 and 55.9 % (v/v) methanolâ ...

Suppression of HD-cooling in protogalactic gas clouds by Lyman-Werner radiation

, 2010
It has been shown that HD molecules can form efficiently in metal-free gas collapsing into massive protogalactic halos at high redshift. The resulting radiative cooling by HD can lower the gas temperature to that of the cosmic microwave background, T_CMB=

Estimated un-ionized ammonia at small incremental pH value and temperatures: practical option for fish farmers [PDF]

, 2012
Ammonia as the primary product of nitrogen metabolism causes mortality due to ammonia toxicity produced in a culture system. Effect of pH and Temperature was calculation and expanded using the acid dissociation constant (pka) for equation: pka = 0.09018+

Determination of ionization constants (PKA) of β-hydroxy-β-arylalkanoic acids using high-pressure liquid chromatography [PDF]

Kragujevac Journal of Science, 2018
pKa values of five β-hydroxy-β-arylalkanoic acids and ibuprofen were determined using the RP-HPLC method. Stationary phase was octadecyl modified (C-18) silica gel, and mobile phase was a mixture of methanol and one of nine different buffers (60:40, v/v).

Förster Resonance Energy Transfer Measurements in Living Bacteria for Interaction Studies of BamA with BamD and Inhibitor Identification

Cells
The β-barrel assembly machinery (BAM) is a multimeric protein complex responsible for the folding of outer membrane proteins in gram-negative bacteria. It is essential for cell survival and outer membrane integrity.

Quantitative analysis of MBW complex formation in the context of trichome patterning

Frontiers in Plant Science
Trichome patterning in Arabidopsis is regulated by R2R3MYB, bHLH and WDR (MBW) genes. These are considered to form a trimeric MBW protein complex that promotes trichome formation.
