Carbohydrates are an important a part of a balanced food plan and supply the physique with the power and vitamins it must operate correctly.
Composed of Carbon, Hydrogen, Oxygen
Carbohydrates are composed of three parts: carbon, hydrogen, and oxygen. These parts are organized in varied mixtures to kind a variety of carbohydrate molecules, from easy sugars to advanced polysaccharides.
Carbon: The Spine of Carbohydrates
Carbon atoms kind the spine of all carbohydrate molecules. They’re linked collectively in chains or rings, creating the construction of the carbohydrate.
Hydrogen and Oxygen: The Supporting Parts
Hydrogen and oxygen atoms are connected to the carbon atoms in carbohydrates. Hydrogen atoms sometimes kind single bonds with carbon atoms, whereas oxygen atoms can kind single or double bonds with carbon atoms.
The Ratio of Carbon, Hydrogen, and Oxygen
The ratio of carbon, hydrogen, and oxygen atoms in a carbohydrate molecule determines its chemical properties and classification. Easy sugars, corresponding to glucose and fructose, have a ratio of 1 carbon atom to 2 hydrogen atoms to at least one oxygen atom (CH2O). Advanced carbohydrates, corresponding to starch and cellulose, have a ratio of 1 carbon atom to 2 hydrogen atoms to a number of oxygen atoms (Cx(H2O)y).
