An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds — that is, a compound that is not an organic compound. [1][2] The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep ...
Alternative biochemistry. Arsenic -based life. Arsenic, which is chemically similar to phosphorus, while poisonous for most life forms on Earth, is incorporated into the biochemistry of some organisms. [citation needed] Borane biochemistry (Organoboron chemistry) Alternative biochemistry. Boranes-based life.
In chemistry, a non-covalent interaction differs from a covalent bond in that it does not involve the sharing of electrons, [1] but rather involves more dispersed variations of electromagnetic interactions between molecules or within a molecule. The chemical energy released in the formation of non-covalent interactions is typically on the order ...
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
The carbon cycle is a biogeochemical cycle that is important in maintaining life on Earth over a long time span. The cycle includes carbon sequestration and carbon sinks. [4][5] Plate tectonics are needed for life over a long time span, and carbon-based life is important in the plate tectonics process. [6]
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. Carbon is tetravalent but carbon free ...
A natural product is a natural compound or substance produced by a living organism—that is, found in nature. [2][3] In the broadest sense, natural products include any substance produced by life. [4][5] Natural products can also be prepared by chemical synthesis (both semisynthesis and total synthesis) and have played a central role in the ...
