AMINO ACID WORKSHEET

 

1. Using the amino acid chart on the back of this worksheet, divide the amino acids into the following groups:  hydrophobic, hydrogen bonding, acidic, basic, amide, small, able to form sulfide bonds.  List the symbol for the amino acids in the space provided.  Use the third row of the chart to indicate the role the amino acids in this group will play in the structure of the protein or other special features.  Not all amino acids will be used.

 

hydrophobic	hydrogen bonding	Acidic or amides	basic	disulfide bond	imino acid

 

2. Using the following amino acid chain:          Cys- Ser –Gly –Asn-Cys

 

1. Will this chain form disulfide bonds?

 

1. Will this chain migrate toward the positive or negative electrode during electrophoresis at pH = 7, or not move at all.

 

2. Study the polypeptide chain below.  It is not yet folded.  Use color pencils as follows:
3. Use a GREEN pencil to connect amino acids that will be attracted through hydrogen bonding
4. Use a RED pencil to connect amino acids that will form a disulfide bond
5. Use a BLUE pencil to connect amino acids that will form ionic bonds with each other
