Questions and Answers with Verified
Solutions | Latest Updated 2026
What is the basic structure of an amino group (NH2 or NH3), carboxyl group
amino acid? What do they look (COO
like? or COOH), alpha carbon (C), and variable
group
How do you identify the 3 different Non-polar/hydrophobic - end with CH or
types of side chains: non- "can't
polar/hydrophobic, polar, and have" water. Polar - end with OH, SH, or
charged? NH.
Charged - end with a charge
what kinds of bonds do each of the ionic, hydrophobic/non-polar, charged
3
different types of side chains
make?
What are the 4 levels of protein Primary - linear structure, Secondary -
structure? Folded into
helix or pleated sheet caused by hydrogen
bonding, tertiary - 3D structure caused by
side
chain interactions, quaternary - 1+ amino
acid chains
combine = multiple subunits MUST have
1+ subunit
, What enviormental change breaks hydrophobic - temperature change, ionic -
each type of bond? salt or
decreased pH, hydrogen - temperature,
change in
pH, disulfide - reducing agents
what type of amino acid side chain hydrophobic bonds
leads to protein aggregration?
how do environmental changes Extreme temp can cause hydrogen bonds
affect protein folding? to break
apart = malformation of protein folding
how do mutations affect protein Can cause structure to change. Protein
structure? loses form
= loses function. May form a different
protein.
What is an electron? Negatively charged atom on outer ring for
bonding
What is energy: Power derived fro chemical interaction
what are covalent bonds? chemical bond, atoms share 1+ valence
electrons
what is an ionic bond? bond between positive and negative
what is a hydrogen bond? weak bond between positive and negative
