proteins

Question 1

name important functions

Answer 1

enzymes

structures keratin

carries and transport aquaporin

cellcommunication signals and recpetors

defense in antibodies

movement in actin

storage bean seed proteins

Question 2

what is their basic structure

Answer 2

monomer= amino acids 20 ones

polymer = polypeptide

protein can be one or more polypeptides bonded together

large and complex shape

complex 3d

Question 3

peptide bonding

Answer 3

C-N BOND

CALLED PEPTIDE BOND

Question 4

primary

secondary

tertiarly

quaternary

Answer 4

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

Question 5

What is Denatuiration

Answer 5

Unfolding a protein

conditions that disrupt H bonds Disulfides ionics

temperature

salinity

pH

alter 2d and 3d
