Synthesis of Proteins:

    This is the print document which evolved into the Protein Web Activity.  Some parts are repetitive, but
others may give you more insight.

1.     Foods rich in proteins include: F _ _ _, _ H _ _ K _ _, _ _ G   _ H _ _ _, & _ _ Y  (a bean)

2.     The four most common elements contained are: _____, ________, _______, & _____

3.     The building blocks of proteins are _ M _ _ _    _ C _ _ S.   Enzymes always contain a large protein portion, therefore the building blocks of enzymes must be ____________.

4.     There are about ___ different amino acids found in our food.  Those which we can NOT make ourselves and must be consumed are the  _ S _ _ N _ _ _ L   amino acids. 

5.     Draw a structural formula of an amino group.  (It contain nitrogen with an atomic number of 7 which contains ___ unpaired electrons available for covalent bonding.

6.      Make a molecular model of an amino group.

7.      Draw the central portion of an amino acid.

8.      Make a molecular model of this central portion.

9.    Draw a structural formula of an organic acid (carboxyl) group (if not done so already)

10.      Make a molecular model of this group.

11.      Draw an amino acid.  (It links the three parts drawn [5 + 7 + 9]

12.  Make a molecular model of an amino acid.

13.  This molecule is known as an amino acid because it contains an  _ _ _ _ _   group on one end

 and a   _ _ _ B _ _ _ _    group on the other end.

14.  When two amino acids are present along with a specific enzyme, they may unite in a synthesis

       reaction.  Draw the two structural formulas of the two molecules which are produced.

                                                                                                            +

15.   The larger molecule above is a di / peptide.  The two atoms which link the two former amino

        acid parts in a dipeptide are ____ & ___.   (Circle these two atoms in the above molecule.)

16.   The name for this unique protein linkage is a     P _ _ _ _ D _    bond.

17.    Make a molecular model of a dipeptide.

18.    As the dipeptide was formed, what other molecule was made?  _________

19.    In what type of chemical reaction was this molecule produced?  __________ ____________

20.    The C-N bond is the peptide bond.  A long protein chain formed by the repeated dehydration 

  synthesis of  many  amino acids is known as a   _ _ L _ P _ _ T _ _ _.   Any long molecule

  made from repeating similar subunits is known as a    P _ _ Y _ _ R.
