The human body uses energy produced by carbohydrate for your cells, tissues and organs. The extra carbohydrates also stored in liver and muscles for when it is needed. Carbohydrates come in a variety of forms. The most common and abundant forms are fibers, sugars, and starches (nlm.nil.gov). Glucose is a common known of sugar and it is one of the standards that were used in this lab. Glucose is a 6 carbon atoms, it is classified as an aldohexose (a hexose with an aldehyde group on one end). There are also other common standard that were used in this lab is fructose. Similar to Glucose, Fructose has 6 carbon atoms, however, it is a ketohexose (a hexose with ketone group on one end) (Bruice 2011). …show more content…
They are monosaccharides, disaccharides, and polysaccharides. Monosaccharides are the simplest units of carbohydrates and a simple carbohydrate. They are the building block of more complex of carbohydrates such as disaccharides and polysaccharides. According to orthomolecular.org, monosaccharides are colorless; they can dissolve in water and have crystal like appearance (orthmolecular.org). Disaccharides are made up of two monosaccharide units linked through glycosidic bond. Polysaccharides are composed of long chains monosaccharides units linked by glycosidic
