Carbohydrate ID Lab

In the carbohydrate lab that was performed in my biology class, we studies monosaccharides, polysaccharides and disaccharides. The three elements that are present in carbohydrates are carbon, oxygen and hydrogen.
Two examples of monosaccharides:
1.) Glucose
2.) Fructose
Two examples of disaccharides:
1.) Lactose
2.) Sucrose
Two examples of Polysaccharides:
1.) Cellulose
2.) Glycogen
In water, there are two hydrogen atoms for every oxygen atom. In carbohydrates, there are 6 hydrogen atoms and 12 hydrogen atoms.
We know that mono means one; di means two; and poly means many. We use these terms in describing the three types of sugars because:
Monosaccharides; contains one monomer
Disaccharides; contains two monomers
Polysaccharides; contains many monomers
We can tell, using the Benedict's solution, that a monosaccharide is present because the solution will turn either a cloudy orange or white color. We can tell, using the iodine solution, when a disaccharide is present because the solution gets heavily darker. We can tell, using the iodine and Benedict's solution, when a polysaccharide is present because there is no change in the solution.
Foods that contain:
Monosaccharides- Fruit
Disaccharides-Corn Syrup
Polysaccharides-Cheerios
