  2. Carbon compounds - Wikipedia

    en.wikipedia.org/wiki/Carbon_compounds

    Carbon compounds. Carbon compounds are defined as chemical substances containing carbon. [ 1][ 2] More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds.

  3. Carbohydrate - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate

    Carbohydrate. Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage. A carbohydrate ( / ˌkɑːrboʊˈhaɪdreɪt /) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 ...

  4. Bisphenol A - Wikipedia

    en.wikipedia.org/wiki/Bisphenol_A

    Infobox references. Bisphenol A ( BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in water. [ 2][ 7] BPA is produced on an industrial scale by the condensation reaction of phenol and acetone.

  5. Polycarbonate - Wikipedia

    en.wikipedia.org/wiki/Polycarbonate

    The use of polycarbonate containers for the purpose of food storage is controversial. The basis of this controversy is their hydrolysis (degradation by water, often referred to as leaching) occurring at high temperature, releases bisphenol A: 1/n [OC(OC 6 H 4) 2 CMe 2] n + H 2 O → (HOC 6 H 4) 2 CMe 2 + CO 2

  6. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component of biological compounds as well as a major component of many ...

  7. Carbon sequestration - Wikipedia

    en.wikipedia.org/wiki/Carbon_sequestration

    Biologic carbon sequestration is a naturally occurring process as part of the carbon cycle. Humans can enhance it through deliberate actions and use of technology. Carbon dioxide ( CO. 2) is naturally captured from the atmosphere through biological, chemical, and physical processes. These processes can be accelerated for example through changes ...
