Biomolecules Post-Lab - Kate Turner | Library

Please do not start this until we discuss it in class.

Remember - you should be using class data to answer these questions!!!

1

Which known substances contain lipids according to the class data (select all that apply)?

1

Which known substances contained a lot of glucose (dark brown) according to the class data (select all that apply)?

1

Which known substances contain starch according to the class data (select all that apply)?

1

Which known substances contained a lot of proteins according to the class data (select all that apply)?

Now, let's look at what you learned about the unknown substance #1. What biomolecules did you find in this substance (select all that apply)?

1

Now, let's look at what you learned about the unknown substance #2. What biomolecules did you find in this substance (select all that apply)?

Now look at these food labels to answer the remaining questions.

These food labels are for the two unknown substances in the lab. You are now trying to figure out which food label matches each of the unknowns.

6.5

Which of these foods do you think the unknown substance #1 could be and which could it not be? Why?

Support your answer with data from the food labels (that means numbers like we were writing when doing the food label worksheet) and with the data you collected during the lab (in this case data does not mean numbers with units, but you should address the data table and specific test(s) - ex: because the paper bag was translucent for substances x and y then these contained lipids). These two questions are the ones worth the most points so you should make these answers beefy.

Are there any results from this lab that you didn't expect based on what you know about distilled water, mayo, gatorade, potatoes, and egg? What were they? Explain.

What might this tell you about the tests we did?

If you expected all of the results (i.e. the tests indicated all of the biomolecules you expected to find in each food) then you can just write that.
