What is the basic structure of an amino amino group (NH2 or NH3), carboxyl group (COO or COOH),
acid? What do they look like? alpha carbon (C), and variable group
How do you identify the 3 different types of Non-polar/hydrophobic - end with CH or "can't have" water.
side chains: non-polar/hydrophobic, polar, Polar - end with OH, SH, or NH. Charged - end with a charge
and charged?
what kinds of bonds do each of the 3 ionic, hydrophobic/non-polar, charged
different types of side chains make?
What are the 4 levels of protein structure? 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 hydrophobic - temperature change, ionic - salt or decreased
type of bond? pH, hydrogen - temperature, change in pH, disulfide -
reducing agents
what type of amino acid side chain leads to hydrophobic bonds
protein aggregration?
how do environmental changes affect Extreme temp can cause hydrogen bonds to break apart =
protein folding? malformation of protein folding
how do mutations affect protein structure? Can cause structure to change. Protein 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
with an amino? piece of amino acid, NH2 or NH3
what is a carboyxl? piece of amino acid, COO or COOH
What is hydrophobic? Doesn't like water, end with CH
what is hydrophilic? Water Lovering, end with OH, NH, or SH
what is disulfide bond? strongest bond between reduction agents, formed between
SH's.
what are zwitterions? amino with positive and negative charges = overall charge
of zero
what is a polypeptide polymer of amino acids
What is dehydration synthesis? Process of forming peptide bonds
what is hydrolysis? adding water to destroy bonds
what is an alpha helix? twisted secondary structure, formed by hydrogen bonds
what is a beta sheet? folded second structure shape, formed by hydrogen bonds
, what is denaturation? loss of shape duet o interruption of chemical bonds; occurs
via extreme salt, temp, pH
