biochemistry for dummies (me, that is...)

... zwitter ions in neutral water solutions... and then, I'll add that aa. can be precipitated nad crystalized and explain the whole intramolecular neutralization, the difference: pKa1 << pKa2 (so, the predominant form is always ionized..) and also add something abouth "ionic character" ...

biochemistry for dummies (me, that is...)

... even as solids; if I start with "dipolar ions"; they aren't always that, and bringing in the definition of "intramolecular neutralization"... So, can I say that they are alway"molecular ions" (although that term isn't quite propriate)... any suggestions?

on singlet oxygen in animal cells

... singlet state. The term "oxygen radical" is a much broader one, and includes superoxide and the more dangerous hydroxyl radical, the neutralization of both being well documented and easy to find, unlike this pesky singlet oxygen. My best hypothesis so far is that singlet oxygen is ...

on singlet oxygen in animal cells

... oxygen species of this kind, cause all sorts of damage to cells, known collectively as oxidative stress. The question I want to ask regards the neutralization of singlet oxygen. A plant cell can easily neutralize this species using caroteinoid pigments. However, animal cells do not have this ...

Acid-Base Equilibria & Neutralization

Sorry. Wrong model. This is a calorimetric determination of heats of neutralization, which is something other than a simple end-point titration. The end-points are the same for strong or weak acids and bases, but the heats evolved are not necessarily the same. ...
