Exposure to stress triggers hormonal and behavioral responses. It has been shown that the endogenous opioid system plays a role in some physiological reactions to stress. The opioid system was described to mediate analgesia induced by mild stressors and
Hi Everyone, I was just wondering if you know of any factors that would affect the dissociation of a strong acid. I know that weak acids are affected by factors such as the common ion effect and temperature, but would this apply to strong acids as well? I only ask because we added.....
the term"dissociation constant" is more frequently used than the term"ionization constant" for the equilibrium constant ofdissociation/ionization of a weak acid/base in water. e.g. Na⁺Cl⁻(s) + aq → Na⁺(aq) + Cl⁻(aq) dissociation(√)ionization(x) ...
Electrolytic dissociation occurs when an electrolyte is dissolved in a polar solvent. For example, when hydrogen chloride, HCl, is dissolved in water to form hydrochloric acid, most of its molecules dissociate into hydrogen ions (H+) and chloride ions (Cl−). Some pure substances spontaneously ...
By contrast, a strong acid (such as hydrochloric acid or HCl) gives up H+ easily and is essentially 100% dissociated in water, and a strong base (such as sodium hydroxide or NaOH) has a high affinity for H+ and holds it tightly (McMurry & Castellion, 2003). In solutions of weak-...
This distinction could not be explained by different amounts of FnBP, as confirmed by Western blots. Rather, amino acid polymorphisms within the Fn-binding repeats of FnBPA explain, at least partially, the statistically (p < 0.05) longer bond lifetime for isolates associated with an infected ...
To overcome unfavorable pharmacokinetic properties, prodrug forms of 23 were developed through the insertion of aminoacidic moieties. Water soluble lysyl amide prodrug 24 (Phortress) showed improved pharmacokinetic profile compared to parent compound, by releasing the active form...
Sensitization of trigeminal caudalis neuronal responses to intraoral acid and salt stimuli and desensitization by nicotine. In human studies, repeated intraoral application of strong acidic or salt stimuli induces irritation that progressively increases across trials (sensitizat... Sudo,Satoko,Makoto,......
And finally the lower the pKa value the stronger the acid is, right? So what about a base that has got a pKa value of around 11, is that a strong base? And how to find out? I know there are a lot of questions and that they are probably quite fundamental, but this is something ...
