many of the reactive primary and secondary nitrogens in PEI remain protonated and thereby become unavailable for crosslinking reactions with the base polymer. 治疗流体的酸碱度和PEI nitrogens的pKa价值定义了多少易反应的主要和次要nitrogens在PEI依然是protonated和从而变得无法获得为交互相联反应与基本的聚合物...
The hydroxyl groups may have acid (pKa = 2.9) or basic character (pKa = 12.7), if they are bidentate or monodentate, respectively (Herrmann and Boehm, 1969). For these reasons the TiO2 surface can be protonated or deprotonated depending on the pH value of the aqueous suspension (Fig. 1.12...
with a more than twofold greater affinity of F-actin binding at pH 6.5 compared to pH 7.5 [152]. This is concomitant with a shorter lifetime of focal adhesions combined with a higher migratory rate
Which statement about pKa is not true? a) It represents a pH at which 50% of the titratable group is in the acid form and 50% is in the base form. b) If the pH is less than the pKa, more than 50% of the titratable groups are unprotonated. c) If the pH is ...
What formula do you use to determine if an acid is protonated or deprotonated when given the pH and {eq}pK_a {/eq}? Acid-Base Reactions: Acids and bases mainly react to form neutral solutions, a reaction termed neutralization reaction. protonation of ...
and this gives rise to the following equation: F ¼ FB Ã10 À nÃpKa þ FBHÃ10 À 10 À nÃpKa þ 10 À nÃpH nÃpH ð2Þ where F is the measured fluorescence and FB and FBH are the fluorescence values of the non-protonated and protonated spe- cies, respectiv...
Almost all known pH-responsive antibodies sense pH due to histidine residues within their variable regions. pKa value of the histidine side chain is about 6; thus, at pH below 6.0, the histidine side chain is mostly protonated, whereas, at physiologic pH 7.4, it is deprotonated. It was show...
Of particular note, we found that the affinity of protonated His for aromatic residues (via cation–π interactions) is greater than the affinity of neutral His for either cationic residues (also via cation–π interactions) or aromatic residues (via π–π interactions). Furthermore, His ...
