Proteins 2 Flashcards
Why do we eat protein?
Proteins are eaten in order to break them down via digestion/hydrolysis
Do we eat proteins for energy?
No, even though they provide 4 calories per gram, we don’t.
We eat the to rather rearrange them into a different protein.
What will give a protein its function and structure?
The order of amino acids will determine the structure and function of a protein.
What are the bonds between Amino Acids after they undergo dehydration synthesis?
After the undergo dehydration synthesis the bonds formed will be peptide bonds (link amino acids together).
What is a dipeptide?
Two amino acids linked together.
What is a polypeptide?
Many amino acids together.
What is the “hierarchy” of proteins?
It is the levels of protein structure.
What is the levels of protein structure?
Primary, secondary, tertiary, and Quaternary.
What is the primary protein structure?
Sequence of a chain of amino acids.
What is the secondary structure?
Occurs when the sequence of Amino acids are linked by hydrogen bonds. This causes them to fold into an alpha helix and pleated sheets.
What is the tertiary structure
Occurs when certain attractions are present between alpha helix’s and pleated sheets.
What are the interactions for tertiary structure?
Disulfide bonds
Hydrophobic interactions
Ionic bonds
What is a Quaternary protein structure?
Protein consisting of more than one amino acid chain. Must be two or more.
