Biochemistry exam is on Monday, 9-28-15
College Board Objectives and Agenda for the Day
College Board: General Topics and Concepts,
Biochemistry
Today's AgendaYou Be the Doc Lab
In this unit we will:
Study carbon
Learn the important biological functional groups
Study organic molecules (carbs, proteins, lipids, nucleic
acids) and their monomers

PPT
Proteins???
Proteins
Proteins
Most structurally & functionally diverse
group of biomolecules
Functions:
involved in almost everything
enzymes
structure (keratin, collagen)
carriers & transport (membrane channels)
receptors & binding (defense)
contraction (actin & myosin)
signaling (hormones)
storage (bean seed proteins)
Proteins
Structure:
monomer = amino acids
20 different amino acids
polymer = polypeptide
protein can be 1 or more polypeptide chains
folded & bonded together
large & complex
molecules
complex 3-D shape
Amino acids
 Structure:
central carbon
 amino group
 carboxyl group (acid)
 R group (side chain)

 variable group
 confers unique
chemical properties
of the amino acid

Nonpolar amino acids
 nonpolar & hydrophobic
Why are these nonpolar & hydrophobic?
Polar amino acids
 polar or charged & hydrophilic
Why are these polar & hydrophillic?
Sulfur containing amino acids
Disulfide bridges
cysteines form cross links
Building proteins
Peptide bonds: dehydration synthesis
linking NH2 of 1 amino acid to
COOH of another
C–N bond
peptide
bond
Building proteins
Polypeptide chains
N-terminal = NH2 end
C-terminal = COOH end
repeated sequence (N-C-C) is the
polypeptide backbone
grow in one direction
Protein structure & function
function depends on structure
3-D structure
twisted, folded, coiled into unique shape
pepsin
hemoglobin
collagen
Protein structure & function
function depends on structure
all starts with the
order of amino acids
what determines that order of
amino acids?
lysozyme: enzyme in tears & mucus that kills bacteria
the 10 glycolytic enzymes
used to breakdown glucose
to make ATP
Primary (1°) structure
Order of amino acids in chain
amino acid sequence determined
by DNA
slight change in amino acid
sequence can affect protein’s
structure & it’s function
even just one amino acid change can
make all the difference!
Primary (1°) structure: Sickle cell
anemia
Secondary (2°) structure
“Local folding”
folding along short
sections of
polypeptide
interaction between
adjacent amino acids
H bonds on
backbone
-helix
-pleated sheet
Tertiary (3°) structure
“Global (whole
molecule) folding”
determined by interactions
between R groups
anchored by
disulfide bridges
stabilized by hydrogen and
ionic ‘bonds’
hydrophobic
interactions
effect of water
in cell
2°
3°
Quaternary (4°) structure
Joins together more than 1 polypeptide
chain
only then is it a functional protein
Chaperonin proteins
Guide protein folding
provide shelter for folding polypeptides
keep the new protein segregated from
cytoplasmic influences
Protein models
Protein structure visualized by
X-ray crystallography
extrapolating from amino acid sequence
computer modelling
lysozyme
Protein structure (review)
3°
R groups
hydrophobic interactions,
disulfide bridges, ionic bonds
4° multiple
polypeptides

interactions,
ionic bonds
1°
aa sequence
peptide
bonds;
determined
by DNA
2°
backbone
H bonds
Think eggs…
Once you cook
‘em, there is
no going back!
Denature a protein
Disrupt 3° structure
pH
temperature
salt
unravel or
denature protein
disrupts H bonds,
ionic bonds &
disulfide bridges
Some proteins can
return to their
functional shape
after denaturation, many cannot!
Love them
