Lab 2E
Purpose- What are the differences in the structures of some common carbohydrates? What are the differences in texture and taste of different carbohydrates? How does their structure affect their characteristics?
Materials- These structures and -Petri dishes, 60x15mm, sterile
-plastic spoons
-paper cups
-tap water

procedure-
Part 1-Gathering structural information
1.Use the internet to find the structure and function of each of the molecules being tested(listed in the materials list section). If a structure is labeled "D" or "L", use the D form. If a structure is labeled "right handed" or "left handed", use right handed form.
Part 2-
1.Label paper towel
place small scoop of each carb by label on paper towel
taste with finger-don't double dip
evaluate sweetness-assign numerical scale, define scale
record value in data table-look up functon later, use picture for type of carb

Data Analysis
My partners and I in my group had a very successful experiment and we finished it totally. We learned many things from this experiment, for example that cellulose is a laxative. There isn't much that i would change or alter about this would be more sweeter materials instead of a lot of bad tasting ones.
reflection
I did not learn a lot from the hands-on part of this lab but I did learn better how to work well with partners. I learned that we can make observations with more of our senses than just our vision and I learned a lot about what carbohydrates are, how they work, and what they do.
