Biological Molecules (Carbohydrates) Flashcards
3 Types of Carbohydrates
Sugar, Startches, Fiber
Function of Sugar
Quickly converted into energy found in soda, cookies, juice, and more.
Function of Fiber
Cannot be digested or used for energy found in beans, legumes, nuts, seeds, and more.
Function of Starches
Takes longer to convert into energy found in bread pasta, rice, and more.
3 Main Types of Carbohydrates
Monosaccharides = Simple Sugars = Galactose, Glucose, Fructose
Disaccharides = Double Sugars, Disaccharides = Lactose, Sucrose, Maltose,
Complex Sugars = Polysaccharides = Whole Grain Foods & Startchy Vegetables
Monosaccharides Breakdown
Glucose is a simple sugar, which is made in photosynthesis, used in respiration and transported in blood.
Disaccharides Breakdown
Sucrose is a double sugar molecule made up of two molecules of simple sugars joined by a chemical bond.
Polysaccharides Breakdown
joining simple sugar molecules together by chemical bonds. cellulose and starch = examples of complex sugars.
First Type of Complex Sugar
Cellulose found in cell walls maintains shape because of strength and tolerates turgor pressure (the pushing on the walls by the full central vacuoles)
Second type of Complex Sugar
Plant cells can change glucose into starch.
Plants store starch as an energy store.
Third Type of Complex Sugar
Glycogen (sometimes called animal starch) is made from glucose by animals as a store of energy in the liver and muscles.
What are Carbohydrates made of
Hydrogen, Oxygen, and Carbon
