Proteins and other jazz Flashcards
What does the function of a polymeric molecule depend on?
Types of units joined together, Order of units joined together, three dimensional structure of polymer.
Which type of bonds do proteins use?
All 5! super complex structure.
Shape of Amino Acid
tetrahedral (triangular prism) shape around the a carbon
Peptide Bond
Carboxyl group + Amino group -> results in loss of an H2O… this is very strong
What makes a protein unique?
R group. Can be very big or as small as a sole H.
Types of R groups
1) Electrically charged side chains 2) Polar but not charged side chains 3)non-polar side chains 4)special cases
Cytesine
can make disulfide “bridges” between polypeptides… with other cytesine amino acids
Primary Structure of Amino Acids
Sequence of Amino Acids
Secondary Structure
interactions of nearby amino acids
Tertiary Structure
Three-dimensional shape of a protein
Quaternary Structure
interaction of polypeptide sub-units
Structural Protein
Organization and support of interior and exterior of cell
Enzyme
type of protein that causes chemical reactions to occur
Membrane Channels
protein that regulates movement of ions or molecules across membranes
Signal Transduction
Proteins that move info from inside to outside of cell or vice versa
