Proteins are biomolecules which do everything in the cell.
Each cell has ~30,000 proteins which do ~30,000 different functions.
Proteins are made up of different amino acids which are arranged in different orders (sequences).
Proteins have different functions because they have different structures because they have different sequences of amino acids.

Amino acids all have an amino group, carboxyl group, and central carbon, but have different R groups.
There are 3 types of R groups: hydrophobic, hydrophilic, and ionic.
Amino acids attach together by forming peptide bonds.
Proteins are made as one long chain (primary polypeptide), then fold over (secondary polypeptide), then twist (tertiary polypeptide).

AMINO ACID
Label 15 strips of construction paper. ​
One side   MONOMER​
The other side    AMINO ACID​
Staple each paper to form a ring
Staple each ring to another, making a long protein “paper” chain.
In between each amino acid, write PEPTIDE BOND.
