Water Flashcards
Henderson-Hasselbalch equation
relates pH, pKa and buffer
concentration
hydrogen bonds
polar molecules disolve easy, ionic, weak, Forms between an electronegative hydrogen acceptor (O, N) and
an hydrogen, the hydrogen donor (H+)
amphipathic
compounds with polar and non polar groups
VdWaals interactions
when two uncharged
atoms are brought very close together, their
surrounding electron clouds influence each other, weak, significant in protein interactions
Noncovalent (weak) interactions among biomolecules in aqueous solvent
Hydrogen bonds; ionic interactions; hydrophobic interactions; Van der Waals interactions
titration curve
a plot of pH vs the amount of
base (NaOH) added until acid is neutralized
Buffers
Intracellular and extracellular fluids have a typical and constant pH 7
Weak interactions in aqueous systems
Hydrogen bond
Ionic and hydrophobic interactions
van der Waals interactions
