Module 2 Flashcards
How do you make a peptide bond?
Through Dehydration (loss of water)
How do you break a peptide bond?
Hydrolysis. (Addition of water)`
How do you identify hydrophobic/non-polar amino acids?
By the peripheral side chains being carbon and hydrogen atoms.
How do you identify polar amino acids?
Contains peripheral side groups have hydrogen associated with nitrogen (NH, NH2), Sulphur (SH), or Oxygen (OH).
How do you identify a charged amino acid?
The peripheral SIDE CHAINS have a positive or negative charge. (all amino acids have charges on backbone).
How do hydrogen bonds form?
By pairing 2 polar molecules.
How do ionic bonds form?
By 2 charged molecules.
What type of bond occurs when you pair Sulphur (SH)?
Disulfide bonds. (Which is covalent).
What types of bonds are disrupted by heat?
Hydrophobic/non-polar.
What types of bonds are disrupted by PH or salt?
Ionic or hydrogen.
What is the 3 sections of “backbone” for an amino acid?
Carboxyl group, Alpha Carbon, and Amino Group.
What is primary protein structure?
A sequence of amino acid chains bound by peptide bonds.
What is secondary protein structure?
Where the backbone of the amino acids create hydrogen bonds and form a repeating pattern (2-demensional).
What is tertiary protein structure?
Three-Dimensional folding patterned formed by side chain interactions (R-group).
What is quaternary protein structure?
The there is more then one amino acid chain binding together. (Not present in all structures).
