1
name important functions
enzymes
structures keratin
carries and transport aquaporin
cellcommunication signals and recpetors
defense in antibodies
movement in actin
storage bean seed proteins
2
what is their basic structure
monomer= amino acids 20 ones
polymer = polypeptide
protein can be one or more polypeptides bonded together
large and complex shape
complex 3d
3
peptide bonding
C-N BOND
CALLED PEPTIDE BOND
4
primary
secondary
tertiarly
quaternary
amino acid sequence determined by DNA peptide bonds
R groups and H bonds
R groups hydrophic interactions Ionic bonds and H ones and disulfide bridges
multiple peptides hydrophobic interactions
5
What is Denatuiration
Unfolding a protein
conditions that disrupt H bonds Disulfides ionics
temperature
salinity
pH
alter 2d and 3d
destroys functionality: some proteins can fixthemselvesmany cannot
