Uses vertical lines for bonds that go back.Uses horizontal lines for bonds that come forward.Places the most oxidized group at the top.usually used to represent the molecular structures of monosaccharides and amino acids. a two-dimensionalrepresentation of thethree-dimensionalstructure of organic molecules. was named after the English chemist SirWalter N.a common way of representing the cyclicstructureofmonosaccharides with a simple three-dimensional perspective.Triose Tetrose HexoseĢ | 1-C-3 | 4 2 | 3-C-1 | 4 The two simplest sugars Note Numerous Chiral Carbons A triose has three carbons a tetrose has four carbons a pentose has five carbons and a hexose has six carbons.Monosaccharides are also classified according to the number of carbon atoms.Ketoses are monosaccharides with a ketonegroup and many hydroxyl (-OH) groups.Aldoses are monosaccharides with analdehydegroup and many hydroxyl (-OH) groups.Most of the names of carbohydrates end in -ose Glucose-What plants make Maltose- used in making beer (disaccharide) Fructose– found in fruit (monosaccharide) Sucrose- Table sugar (disaccharide) Lactose – In milk (disaccharide) Polysaccharides contain many monosaccharides.Disaccharides consist of two monosaccharides.Monosaccharides are the simplest carbohydrates.In respiration, glucose is oxidized in living cells to produce CO2, H2O, and energy.Photosynthesis in plants requires CO2, H2O, and energy from the sun and produces carbohydrates, such as glucose.Also called saccharides, which means “sugars”.A major source of energy from our diet.Structures of Some Important Monosaccharides.D and L Notations from Fischer Projections.Dietary fiber can't be broken down and absorbed by your digestive system. You probably know that you should eat plenty of fiber, but do you know how much fiber you need, how fiber contributes to good health, or which foods are good sources of fiber? Dietary fiber consists mainly of cellulose, so it is found primarily in plant-based foods, including fruits, vegetables, whole grains, and legumes.
\): Beans are an excellent source of both soluble and insoluble fiber.
