Lab 2E
Cellulose
Startch
Dextrose
Sucrose
Procedure
Materials:
Sucrose Maltose Petri Dishes, 60 x 15 mm, sterile
Glucose Lactose Plastic spoons
Fructose Soluble Starch Paper cups
Galactose Cellulose Tap water
Part 1:
Find images of these eight carbohydrates: Sucrose, Dextrose, Fructose, Galactose, Maltose, Lactose, Soluble Starch and Cellulose
Part 2:
Take a small spoonful of each carbohydrate and place and label them separately on a sheet of paper towel. One by one put a fingertip in each carbohydrate and taste them. Then on a sheet of paper note the texture and sweetness (on a scale of choice ex. 1-10 or 1-100). Also, write down the color of the carbohydrate and the type of structure and that carbohydrate's uses.

Data Analysis: The sweetest carbohydrates were glucose and sucrose.The more rings the carbohydrate had, the less sweet it seemed to be. There seemed to be no other characteristics that had to do with the amount of rings. The testers could have not tasted the same amount of sweetness due to personal preference, the location where they placed the carbohydrates on their tongue and the sensitivity of their taste buds.
Reflection:
The most interesting (and tasty) part of this lab was eating fructose. It was by far the sweetest carbohydrate on the list. My partner and I worked very well together. No general problems or issues. Next time I would try not to eat as much cellulose as I did. This lab was very fun, tasted good and I would do it again with different substances in which their molecular structure and taste crresponded with each other.
