This article is about the chemical elements of biochemistry. For people named Chon, see Chon (name). For other uses, see Chon (disambiguation). Show CHON is a mnemonic acronym for the four most common elements in living organisms: carbon, hydrogen, oxygen, and nitrogen. The acronym CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth. They were created in stars in outer space a long time ago and when a supernova occurred, these elements were sent into space. [1] All of these elements are nonmetals.
In the human body, these four elements compose about 96% of the weight, and major minerals (macrominerals) and minor minerals (also called trace elements) compose the remainder.[2] Sulfur is contained in the amino acids cysteine and methionine.[3] Phosphorus is contained in phospholipids, a class of lipids that are a major component of all cell membranes, as they can form lipid bilayers, which keep ions, proteins, and other molecules where they are needed for cell function, and prevent them from diffusing into areas where they should not be. Phosphate groups are also an essential component of the backbone of nucleic acids (general name for DNA & RNA) and are required to form ATP – the main molecule used as energy powering the cell in all living creatures.[4] Carbonaceous asteroids are rich in CHON elements.[5] These asteroids are the most common type, and frequently collide with Earth as meteorites. Such collisions were especially common early in Earth's history, and these impactors may have been crucial in the formation of the planet's oceans.[6] The simplest compounds to contain all of the CHON elements are isomers fulminic acid (HCNO), isofulminic acid (HONC), cyanic acid (HOCN) and isocyanic acid (HNCO), having one of each atom.[7] See also[edit]Wikimedia Commons has media related to CHNOPS.

What has carbon, oxygen hydrogen and nitrogen in it?Table 1 Organic Compounds. What does carbon, oxygen and hydrogen form?In either case, what you have is the combination of carbon, oxygen, and hydrogen. Carbon and oxygen atoms love to link up with each other and form carbon dioxide. Right behind them in the race to merge come hydrogen and oxygen, which love to form di hydrogen oxide.
Where do carbon nitrogen and oxygen come from?Carbon, nitrogen, and oxygen are thought to originate primarily from stars of different mass ranges; O is synthesized mostly in massive stars (MSs; M > 10 M⊙), while C and N are produced in both MSs and intermediate-mass stars (IMS).
What amino acids compose carbon, hydrogen nitrogen and oxygen?Proteins are compounds composed of carbon, hydrogen, oxygen , and nitrogen , which are arranged as strands of amino acids . They play an essential role in the cellular maintenance, growth, and functioning of the human body.
