Flashcards in Proteins Deck (15):
What are the proteins functions?
1. enzyme catalysts
3. transport (carry out the orders directed from your genes)
5. motion (ATP)
6. regulation (hormones)
What is the information flow?
What is the backbone?
It's a sequence that repeats. NCC NCC NCC (N-Terminal to C-Terminal)
What is hydrophobic?
Doesn't like water, non polar
What is hydrophilic?
Likes water, polar
Main chain atoms bond to form..?
Primary structure in protein
R-Groups or side chains bond to form..?
How are amino acids bond together?
Peptide bond [dehydration synthesis (water is removed)]
Protein Primary Structure
A Specific sequence of amino acids are linked by peptide bond forming a string of amino acids
Each protein type has a unique sequence of amino acids
Protein Secondary Structure
due to H-bonding in main chain it forms:
-Beta (B-pleated sheet)
Protein Tertiary Structure
(Folding of ONE polypeptide)
-Hydrophobic interactions including hydrophobic exclusions
-Disulfide bridges between cysteines
Protein Quaternary Structure
Union of two or more polypeptides held by the same interactions between side chain functional groups seen 3°- level
