Chemistry of Living Things ORGANIC AND INORGANIC COMPOUNDS

Organic and Inorganic Compounds Living things are made up of inorganic and organic compounds. Compounds that do not contain both carbon and hydrogen are called inorganic compounds. The principal inorganic compounds found in living things are: water salts inorganic acids inorganic bases

Organic and Inorganic Compounds Organic compounds are compounds that contain both carbon and hydrogen. The classes of organic compounds found in living things are: Carbohydrates Proteins Lipids Nucleic acids

Carbohydrates Carbohydrates are the main source of energy for cell activities. Ex.: starch and sugar Carbohydrates are made up of the elements carbon, oxygen, and hydrogen. Generally, there are twice as many hydrogen atoms as oxygen atoms in carbohydrates (2:1 ratio).

Carbohydrates The simplest carbohydrates are called monosaccharides or simple sugars. They are called the “building blocks” of carbohydrates. A common monosaccharide is glucose (C 6 H 12 O 6 ). Glucose is formed during photosynthesis.

Carbohydrates When two simple sugars combine, they form a disaccharide or double sugar. Maltose (C 12 H 22 O 11 ) is an example of a common disaccharide. Maltose is formed when two glucose molecules chemically combine.

Carbohydrates Long chains of monosaccharides (sugar molecules) bonded together form polysaccharides. Important polysaccharides found in living things are starch and cellulose.
