Carbohydrates are organic compounds the are arranged as ring structures and are constantly composed the the facets carbon, hydrogen, and oxygen. Carbohydrates space truly hydrates the carbon due to the fact that the proportion of hydrogen atoms to oxygen atom is always virtually 2:1, together in H2O.

You are watching: The carbohydrates seen here contain three common elements. they are

They likewise have plenty of functions. Many of the energy you receive originates from the carbohydrates that you eat. Plants make carbohydrates such as wheat, corn, and also potatoes. Carbohydrates are generally consumed by animals either by eating the plant that made it or through eating various other animals. Humans also receive carbohydrate from entirety grains, fruits, vegetables, milk, candy, soft drinks, and also pasta.

Insects to produce the carbohydrate chitin together a difficult exoskeleton for protection, and also lobsters and crabs usage chitin for their shells. Finally, cellulose is probably the many widely provided carbohydrate compound, consisting of wood and wood products, such as paper.


The easiest biologically essential carbohydrates are monosaccharides, an interpretation one street (mono = one, saccharide = sugar). The general formula for any carbohydrate is (CH2O)x wherein x is any type of number between three and also eight. The most typical monosaccharides (hexoses) space glucose, galactose, and fructose.

Glucose is the easiest monosaccharide and also probably the most acquainted sugar, especially if friend have been in the hospital. In nature, glucose is the sugar that green plants develop during photosynthesis. It is also the main resource of power for cells. Medical procedures frequently require a glucose IV because that recovering patient to regain their strength an ext quickly. Galactose is found in milk, and fructose offers fruit a sweet flavor. Back the chemical structure of every sugar differs, the chemical formula is the same: C6H12O6.


Monosaccharides are joined with each other by dehydration synthetic to type disaccharides, or dual sugars (di = two). The dehydration synthetic reaction publication water dehydration as a by-product. The most common disaccharide is sucrose, likewise known as table sugar, C12H22O11. Other common disaccharides encompass maltose (malt sugar) and also lactose (milk sugar).


Further dehydration adds much more sugar molecules with each other to type long chains well-known as polysaccharides. A polysaccharide usually refers to a carbohydrate polymer consisting of hundreds, even thousands the monosaccharides covalently external inspection together. Cells usage polysaccharides for a number of reasons, including the warehouse of overabundance glucose as starch in plants and also glycogen in animals. The big polysaccharide cellulose is a structural component uncovered in tree that offers them your rigidity and also flexibility.
