Mrs. Paparella Living Environment Polymers Worksheet `Name:______________________________#___ This is a model of a __________________________________. There are __________ subunits present. Another name for a subunit is _________________________. If this is a model of starch , the whole thing is an example of a ________-saccaride. Each individual subunit is then called a ________________________________. The word saccharide refers to ________________. C6H12O6 is called a simple sugar or ___________________. The lab test performed for simple sugars used __________________________ solution as the ____________________________. It turned from _______________________ to ___________________________ when the test tube was ___________________________. The test performed for starch used _______________________________. The solution turned from red to ____________________ if the test was positive. This molecule below ( in the long form) would test ______________(+ or -) with Benedict’s solution and test ______________(+ or -) with Lugol’s Iodine solution. If you wanted to break up the long chain you could use an_____________________. An example of an enzyme is __________________. This enzyme is found in your __________________________. It will break down the complex__________________ found in a cracker to a simple______________________. Design an enzyme shape that could be used to digest the starch. Draw it in an appropriate spot of the molecule below. Protein Synthesis OH alanine H OH Phenylalanine OH OH glycine serine H H H OH cysteine H OH valine H These are several different models of the monomers that make up a protein. These monomers are called _______________________________. In order for them to be joined together, a water molecule must be removed. One part of the water molecule is the H and the other part is the_______________. When water is created as a by-product in the joining of the molecules, the process is called dehydration _________________. Cut out the molecules and put them in this order: cysteine—valine--glycine—serine—phenylalanine-alanine— You will now join them together by cutting out the necessary –OH and –H. You only cut them out when you join 2 together. Cut on the solid black lines of the–OH and –H. Save the -OH and –H and put them next to each other to make water. How many water molecules do you make from joining these 6 subunits?___________________. What do you notice about the ends where you join the 2 subunits? ___________________________________. The bond that joins the tow amino acids together is called a ____________________ bond. Many amino acids joined together are called a ___________________________________. It takes about _____________ amino acids joined together to make a _______________________. Three uses of proteins in the human body are: _______________________________________________________________________________.
