protiens ap bio Flashcards
protiens
CHON
what to know about protiens
- polymers formed from amnio acids
- made up of one carbon atom
- forms 4 covalent bonds
- r groups
amnio acids toghetr create what
dehydration syntheisi\
amnio of one group and carboxyl of other
covalnt bond btwn them is peptide bond
polypeptide
many peptides in a row
primary structure of proteins
formed with translation at a ribsone
primary structure
chain of amino acids
secondary structure
form alpha helix or beta pleated from hydrogen bonding
teritary structire
alpha helix and beta sheets fold due to the R group
quaternary structure
two or more sepertae amnio acid chains interacting and bonding togheter
alpha helix
curls
beta pleated
zig zag
what does the R group do
-determines the chemicla propeties
-influcned by the enviormnet
chains that are hydrophlic
fold outward towards the envionet
ins that are hydropbic
face the inside of the protien
how do protein structures denature
when hydrogen bonds are disrupted
