MONOSACCHARIDE! YAY!
What kind of bond does Cellulose have vs Starch and glycogen? -
ANS-BETA 1, 4 vs the ALPHA of starch and glycogen (some α 1,6 in
there too!)
Basic structure of an Amino Acid - ANS- a central carbon atom
attached to a hydrogen, an acidic carboxyl group (−COOH), an amino
group (−NH2) and an organic side chain (also called an R group)
What is the only amino acid that is NOT CHIRAL? - ANS-Glycine
Naturally-occuring amino acids are L-enantiomers. T/F? Fischer
projection? - ANS-True!! Fischer projections of amino acids have
amino group to the left!
What is a zwitterion and how does an amino acid look as such? -
ANS-They are dipolar ions where each half neutralizes the other.
, Amino acids are amphoteric. Why? - ANS-They can act as an acid or
a base. They have at least two dissociation constants (from H's on
the n and c terminus)
When does an amino acid take on the zwitterion form? - ANS-At the
isoelectric point or isoelectric pH between pKa₁ and pKa₂
Titration of Amino Acids (Glycine) - ANS-
What looses an H first in basic titration, the amino or carboxyl
group? - ANS-The carboxyl group duh!
Things to know about titration of amino acids... - ANS-1.Buffering
capacity is greatest at the Ka's
2. Two moles of base need to be added in order to deprotonate one
mole of most a.a.
3. When adding base, the carboxyl group looses the H first.
4. Titrations can be done in reverse starting with a basic solution
and adding acid.
Free Radical Halogenation - ANS-
What free radical is most is likely to be formed from bromination? -
ANS-A tertiary radical (Most stable)
Combustion - ANS-
Pyrolysis (Cracking) - ANS-
