Sweetness Lab Analysis
The purpose of this lab was to study the level of sweetness of different carbohydrate structures. Based on our observations during our Sweetness Lab, we found that monosaccharides are generally sweeter than both disaccharides and polysaccharides. We found that the four sweetest Carbohydrates were sucrose (100), glucose (80), fructose (130), and galactose (50), all but one monosaccharides. The three least sweet Carbohydrates were lactose, starch, and cellulose, a disaccharide and two polysaccharides. The monosaccharides were also more commonly found in fruits, which taste sweet. This proves that monosaccharides are generally sweeter because three out of the three monosaccharides in our experiment were in the top 4 sweetest carbs, and two out of the two polysaccharides were in the bottom three.
Carbohydrate structures might affect how they are used by cells and organisms because different structures or number of rings make up different saccharides. These different saccharides have different amounts of energy which can be used in different ways in the body. Some only have a little energy and can only do small tasks, while others have a lot of energy and do big tasks in our bodies. That is how the different carbohydrate structures might affect how they are used in organisms.
No, all the testers in our classroom did not give the sample the same rating. One reason why could be that we have different tastebuds. Another reason could be that we have different tastes in food. Some people might not eat or like sugar as much as others, and so the sugars will taste excessively sweet to them. A third reason could be that the testers got different amounts of sugar, making it taste sweeter or more bland. Humans taste sweetness because each person had taste buds, which contain about 50-100 taste cells inside. About 25% respond to sweetness, and the rest split between other tastes.
The tongue tastes using taste buds, according to live science.com. Testers could rank the sweetness of the samples (same samples) but this time have a fixed amount they have to pick up.
