PROTEINS
polymers made up monomers called AMINO ACIDS
:star:
amino acid classification
:three:
cyclic amino acids
its side chain is bonded to the backbone nitrogen as well as to alpha carbon
:four:
:A:
hydroxyl containing amino acids
:B:
sulfur containing amino acids
:two:
aromatic amino acids
contain benzene-like structure in their side chain
:five:
basic
:six:
:A:
acidic amino acids
:B:
amides of acidic amino acids
:one:
aliphatic amino acids
have only carbon and hydrogen in their side chain
:star:
hierachy
:two:
secondary structure
general 3-D forms of local segments of proteins; alpha helix and beta pleated sheet
:three:
tertiary structure
group of alpha helix and beta sheet fold further and cross-link with one another to form a stable 3-D shape
:one:
primary structure
the exact and unique sequence of amino acids residues specified by genetic info
:four:
quaternary structure
fouth level of organization exists for proteins with more than one chain
:star:
types
:one:
fibrous
hard, long, fibrous. insoluble in water
:two:
globular
compact, folded, have groove, soluble in water
:star:
denaturation
disruption of protein's native conformation
