Amino Acids Flashcards
How do amino acids bond together
Through peptide reaction condensation( most likely peptide )
What causes the tertiary structure of a polypeptide chain
The bonding of a amino acids
Do all proteins have a quaternary structure of hemoglobin
No
Describe quaternary structure of hemoglobin
4 strand of protein like yarn ball
List 6 of the functions of protien in living organisms
1) Movement
2) Enzymes(allows chemical reactions, without needing heat)
3) structured parts of cell + tissues, hair, nails and skin
4) molecule for transport of all substances into cells
5) chemical messengers(allow body to communicate)
6) blood clotting
7) antibodies
what does the R stand for
The R group
how is a dipeptide formed and what is produced in the action
When two amino acids are joined together, a dipeptide is formed. … A process called dehydration synthesis is used to join amino acids by forming a peptide bond. During this process, a molecule of water (H2O) is removed (dehydration) in order to synthesize a dipeptide
what is polypeptide
a long chain of amino acid bonds
what stage do you start calling them proteins
tertiary
what is quaternary
a bunch of tertiary bunched up
ex of quaternary structure
hemoglobin
what is a peptide bond
2 amino acids join by forming a peptide bond and h20 is released through condensation/dehydration
diff between peptide and dipeptide
The difference between peptide and dipeptide is that a peptide is a short chain of amino acids that link with each other via peptide bonds whereas a dipeptide is a form of peptide that has either two amino acids joined with single peptide bond or single amino acid with two peptide bonds.
what causes the folding of amino acid chains
because they attract/repel other amino acids making it fold
