The “p” in pH, pKa, and pI denotes the negative logarithm, to base 10, of the parameter in question. Logarithms transform a nonlinear series of values into a linear series. E.g., the logarithm (to base 10) of, 10, 100, 1000, and 10,000 is 1, 2, 3, and 4 respectively. ...
1E and Supplementary Fig. S2A). Therefore, the strength of JNK signals generated by TNFα was negatively correlated with pHi both between different cell types and within the same cells over time. Fig. 1: Intracellular pH (pHi) modifies stress-stimulated activation of JNK MAPK. A ...

aBecause HF is weakly ionized in solution at low pH values (pKa ? 3.2), the corresponding uptake of fluoride is reduced at an acidic pH, and consequently a fraction of the fluoride becomes unavailable for adsorption. Our experimental minimum pH condition was 3.5, so this pH may be close to...
Proton titration data for the N-terminal β -domain fit a simple model with three ionizations of the same apparent pKavalue of 4.9 and a collective binding constant for zinc of 5× 10-12M at pH 7.0. The zinc cluster in the C-terminal α -domain is more stable than that in the β ...
and Campylobacter spp. at a neutral pH. PPIs exert no specific antibacterial action since binding to a particular target was not observed. PPIs bind to a broad range of intracellular proteins in Helicobacter spp.; binding was enhanced in an acidic environment. The lipophilic nature of PPIs may ...
Use this lesson plan to teach your students about titrations of acids and bases. Students will watch a video lesson that defines and explains titrations and shows how to determine pH during titration. Hands-on activities and a quiz help students understand content. Related...
如图所示，在平面xOy内有一沿x轴正方向传播的简谐横波，波速为3.0m/s，频率为2.5Hz，A、B两点位于x轴上，相距0.90m.分别以A、B为平衡位置的两个质元在振动过程中，取A点的质元位于波峰时为t=0，对于B点的质元来说（ ）
As far as I remember, the first acidity is strong and the second has a very low pKa : do you titrate the total H+, then, or do you see both acidities somehow ? Quote from: Corribus on December 06, 2019, 10:30:50 AM Testing your water at home for impurities or pH (e.g., ...
