Summary
Carbon forms four covalent bonds, allowing chains, rings and the huge variety of organic molecules in living things.
In depth
Carbon has four valence electrons and forms four stable covalent bonds, including single, double and triple bonds, so it can build chains, branches and rings. Hydrocarbon skeletons carry functional groups such as hydroxyl, carbonyl, carboxyl, amino, sulfhydryl and phosphate that give each molecule distinct properties.
Isomers share a formula but differ in structure, for example glucose and fructose (both C6H12O6), which have different roles.
Key idea: function in biology is determined by the shape of the carbon skeleton and the attached functional groups.
Frequently asked questions
What is Carbon Chemistry?
