# 3-1 Kitchen Chemistry/Biology

Search your kitchen for food and the chemicals that are found in your food. List three different chemicals found as part of or in your foods, spice or specific compounds used as cooking ingredients which can be found in your kitchen. If possible, list compounds that others in the class have not already. This may be "trickier" than it looks... hint, do not list plant parts like "peanuts", "mint leaves", "tomatoes", etc. that are themselves made of many chemicals. You can list a chemical component found within peanuts or tomatoes, etc. For each chemical you list, (1) what food was it in or associated with, (2) is it "organic" or "inorganic" (using the correct chemical definitions), and if it is organic, (3) is it "protein", "lipid", "carbohydrate", "nucleic acid", or some "other" organic chemical. Also, briefly describe your kitchen search experience in completing this blog assignment. (How did you find and determine the chemicals you listed.)

Alright, so I went in my pantry looking at all the different kinds of foods I had. I sorta knew what i wanted to find, like I knew most of the foods I have have salt and that is a chemical so i look at the peanut butter I have and it says it contains Sodium, which is NaCl - Sodium Chloride. This chemical, NaCl, is not organic because it doesn't contain Carbon.

That was really the only chemical that I initially thought of. So them I looked in the ingredients for the jelly that I had and it said it contains Citric Acid. I know that Citric Acid is a chemical, but I had to do a little research to find out if it was organic or not. So I used Wikipedia and sure enough Citric Acid is organic. The Molecular formula for Citric Acid is
C6H8O7. So since it contains Carbon, we can conclude that it is organic. As for whether it is a lipic, carbohydrate, nucleic acid or other organic chemical. I am going to have to say it is just some other organic chemical.

For the third chemical I decided i would look at the ingredients for the tuna that was sitting on my shelf. I noticed that there was Pyrophosphate in the tuna. I think that it is part of the broth in the can. Well just like the Citric Acid, I had to do a little research. So I turned to my trusty steed, Wikipedia, again and found out that Pyrophosphate is an acid anhydride of phosphate. The molecular stucture is
P2O74− and since it doesn't contain Carbon, we can say that Pyrophosphate is not organic.


So thats about it. If you have any thought feel free to share.
