  • What the hell is PKa and how is it different to pH? (Gold for . . . - Reddit
    Because it is the negative log (base 10) of the Ka, the lower the pKa, the stronger the acid Also, as derived from the Henderson-Hasselbalch equation, when the pH is equal to an acid's pKa, the acid is 50% deprotonated and the concentrations of the acid and it's conjugate base are equal
  • pI, pKa, pH : r Mcat - Reddit
    However, sometimes molecules can have more than two pKa values, so you’ll wanna practice some problems when it comes to calculating pI pKa: tells you how strong weak an acid is A LOW pKa is a STRONG acid, so a HIGH pKa is a WEAK acid I like to remember that pKa and Ka are opposites: if pKa is low, Ka will be high
  • MCAT Biochem: pKA values to know for amino acids? : r Mcat - Reddit
    Two questions Why is pKA of amino acid even relevant? Like there are 2-3 ionizable groups depending on amino acid, so pKa refers to a specific group So how do you know which pKA group to memorize for amino acids Also which pKas should we even memorize? And should we memorize pI as well?
  • What is pKa? : r chemistry - Reddit
    pKa is a human friendly version of Ka used to compare relative acidity without looking at numbers with (×10 -5) a bunch The Ka itself tells you how far the acid will react with water to form it's conjugate base and hydronium
  • ELI5 How do pH, pI, and pKa relate? : r Mcat - Reddit
    Please correct me if im wrong but for me, I understand it as this: pH = concentration of available H+ ions (i e , from water, acid, base etc ) inside the solution And there can be other molecules in the solution that are affected by the availability of H+ ions low pH = high [H+] = acidic high pH = low [H+] = basic Therefore, some molecules can be either protonated or deprotonated pKa= how
  • r PKA on Reddit: Anyone else find the hosts reaction to the news of . . .
    I’ve watched PKA long enough to know that woody probably gave Taylor a call and spoke to him for like an hour or two Reply reply DREDAY_94 • I know the vibe is that the hosts don’t talk a lot behind the scenes but this seems like the most likely scenario Reply reply urekmazinn • you think taylor has hour long private convos with woody
  • increase decrease in pKa?? : r Mcat - Reddit
    The way I interpreted this one, the pKa is higher in the binding pocket due to instability The passage notes that in the binding pocket, nearby Glu experience repulsion, whereas free Glu can form stable H-bonds The more stabilized the conjugate base (AKA the deprotonated, anion form), the stronger the acid
  • pka : r Mcat - Reddit
    Recall that the pKa is the pH at which half of the species are protonated and half are deprotonated To achieve this, the pH must be above the pKa of the COOH (to fully deprotonate all of that group) and below the R-COOH group (to avoid the deprotonation of that group)
