Term
antiparallel
Definition
opposite facing chains hydrogen bond. more stable
Term
parallel
Definition
same facing chains hydrogen bond so that c bonds with n 2 down the chain. less stable
Term
turns and loops
Definition
types of secondary structure
Term
beta turn
Definition
H bond carbonyl + 3rd residue NH. small aas
Term
loops
Definition
not as tight as turn but can have larger structures
Term
tertiary structure
Definition
disulfide bonds. salt bridges. hydrophobic interactions (Van der Waals) hydrogen bonds
Term
porins/ membranes
Definition
reverse hydrophobic outside and hydrophilic inside
Term
quaternary structure
Definition
non covalent interactions b/w tertiary subunits
Term
random coil
Definition
denatured state, folding is changed so protein loses function
