essential to the structures and activities of life
Make up 50% of dry weight of cells
Contain carbon, hydrogen, & oxygen PLUSnitrogen and sometimes sulfur
Proteins are involved in:
-cellular structure
-Movement (muscles)
-Defense (antibodies)
-Transport (blood)
-Communication
Monomers are called amino acids

~The Structure of Proteins~
20 common amino acids that can make literally thousands of proteins.
Their diversity is based on different arrangements of amino acids
R = variable group- which distinguishes each of the 20 different amino acids
( I have a religion test today and I'm going to fail :)
~ Amino acids can be linked by peptide bonds~
(What does this have to do with proteins ???? )
Cells link amino acids together by dehydration synthesis
The bonds between amino acid monomers are called peptide bonds
( Somebody is eating goldfish and I really want to strangle them because I want goldfish but I cant have goldfish help me )
~A protein's specific shape determines its function~
A protein consists of polypeptide chains folded into a unique shape
The shape determines the protein's function
A protein loses its specific function when its polypeptides unravel
