PROTEINS! Cancer 6 UNIT What replicates DNA? What condenses DNA into chromosomes? What lines up chromosomes in the middle? What pulls chromosomes apart? What pulls two cells apart? What “checks” for mutations at the checkpoints? What tells the cell to divide when another cell dies? What transports nutrients into the cell and waste out of the cell? What digests cellular food and builds new molecules? PROTEINS!

UNIT 7 Proteins

Proteins 7 Proteins are biomolecules which do everything in the cell. UNIT 7 Proteins Proteins are biomolecules which do everything in the cell. Each cell has ~30,000 proteins which do ~30,000 different functions. https://m.youtube.com/watch?v=wJyUtbn0O5Y

Proteins 7 Proteins are biomolecules which do everything in the cell. UNIT 7 Proteins SEQUENCES 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). amino acids

Proteins 7 Proteins are biomolecules which do everything in the cell. UNIT 7 Proteins SEQUENCES STRUCTURES 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.

UNIT 7 Proteins Amino acids all have an amino group, carboxyl group, and central carbon, but have different R groups. THE R GROUP amino group central carbon carboxyl group

Proteins 7 R GROUP R GROUP R GROUP UNIT 7 Proteins Amino acids all have an amino group, carboxyl group, and central carbon, but have different R groups. R GROUP R GROUP R GROUP

UNIT 7 Proteins Hydrophobic 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. Hydrophilic Ionic

UNIT 7 Proteins 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. peptide bonds

UNIT 7 Proteins 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). tertiary primary secondary tertiary primary secondary

Let’s Build a Protein 7 AMINO ACID UNIT 7 Let’s Build a Protein 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.
