What is the basic structure of an amino acid? What do they look like? - correct answer amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group
How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? - correct answer Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge
what kinds of bonds do each of the 3 different types of side chains make? - correct answer ionic, hydrophobic/non-polar, charged
What are the 4 levels of protein structure? - correct answer Primary - linear structure, Secondary - 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 each type of bond? - correct answer hydrophobic - temperature change, ionic - salt or decreased pH, hydrogen - temperature, change in pH, disulfide - reducing agents
what type of amino acid side chain leads to protein aggregration? - correct answer hydrophobic bonds
how do environmental changes affect protein folding? - correct answer Extreme temp can cause hydrogen bonds to break apart = malformation of protein folding
how do mutations affect protein structure? - correct answer Can cause structure to change. Protein loses form = loses function. May form a different protein.
What is an electron? - correct answer Negatively charged atom on outer ring for bonding
What is energy: - correct answer Power derived fro chemical interaction
what are covalent bonds? - correct answer chemical bond, atoms share 1+ valence electrons
what is an ionic bond? - correct answer bond between positive and negative
what is a hydrogen bond? - correct answer weak bond between positive and negative
with an amino? - correct answer piece of amino acid, NH2 or NH3
what is a carboyxl? - correct answer piece of amino acid, COO or COOH
What is hydrophobic? - correct answer Doesn't like water, end with CH
what is hydrophilic? - correct answer Water loving, end with OH, NH, or SH
what is disulfide bond? - correct answer strongest bond between reduction agents, formed between SH's.
what are zwitterions? - correct answer amino with positive and negative charges = overall charge of zero
what is a polypeptide - correct answer polymer of amino acids
What is dehydration synthesis? - correct answer Process of forming peptide bonds
what is hydrolysis? - correct answer adding water to destroy bonds
what is an alpha helix? - correct answer twisted secondary structure, formed by hydrogen bonds
what is a beta sheet? - correct answer folded second structure shape, formed by hydrogen bonds
what is denaturation? - correct answer loss of shape duet o interruption of chemical bonds; occurs via extreme salt, temp, pH
what is aggregation? - correct answer clumping of inner or outer cellular proteins caused by misfolded proteins leading to diseases such as Alzheimers, ALS, Parkinson's
how do enzymes catalyze reactions? - correct answer bind with substrates to decrease activation energy required and decrease reaction rate
how do enzymes affect reaction rate and activation energy? - correct answer decrease activation energy and decrease reaction rate
