Organic Chemistry : Carbohydrates Quiz
Carbohydrates are monomers and polymers made up of carbon, hydrogen and oxygen. They originate as products of photosynthesis. They are a major source of metabolic energy and are present in most foods.
The simplest carbohydrates are monosaccharides, which are simple sugars. Examples of monosaccharides include glucose and fructose. Monosaccharides are building blocks for more complex molecules such as nucleic acids.
Simple sugars formed from two monosaccharides via condensation are called disaccharides. Sucrose (C12H22O11), which is table sugar, is a disaccharide. It is a combination of glucose and fructose, and is the most abundant disaccharide.
Large chains of monosaccharides are called polysaccharides. Polysaccharides serve for the storage of energy in the form of starch and glycogen. Starches in plants are polysaccharides made of multiple glucose chains. Glycogen is a polysaccharide starch-like substance produced in animals. Cellulose, an abundant biomolecule, is a glucose polymer that is insoluble in water and found in plants and the chitin of arthropods.
