Carbon
The Carbon atom usually forms the backbone of polymers and quite often oxygen can do also as in polyether polyols etc.

Hydrogen bonds are weak attractions between a hydrogen atom and a highly electronegative atom like oxygen or nitrogen. In biological molecules, hydrogen bonds help hold the molecules together and contribute to their stability by forming strong connections between different parts of the molecule. This helps maintain the structure and function of biological molecules like proteins and DNA.
Deoxyribose is a five-carbon sugar that is a component of DNA molecules. It is similar to ribose sugar but lacks an oxygen atom on the second carbon. Deoxyribose sugar forms the "backbone" of the DNA molecule, connecting the nucleotide bases.
A 12C atom, which is a carbon atom with six protons and six neutrons, is essential for life as it forms the backbone of organic molecules. It enables the structure of carbohydrates, proteins, fats, and nucleic acids, all of which are crucial for biological processes. Additionally, 12C is used in various applications, including carbon dating in archaeology and medicine, as well as being a key component in materials like plastics and fuels. Its stability and abundance make it fundamental to both natural and industrial systems.
The monosaccharide in all RNA molecules is ribose. Ribose is a five-carbon sugar that plays a crucial role in the structure of RNA, where it forms part of the backbone along with phosphate groups. In contrast, DNA contains deoxyribose, which lacks one oxygen atom compared to ribose.
The bonds that connect hydrogen molecules to oxygen molecules in water are covalent bonds. In a water molecule, each hydrogen atom forms a covalent bond with the oxygen atom by sharing electrons.
Carbon atoms can bond together to form single, double, and triple bonds, long chains, branched chains, and rings, which enables carbon to form so many different compounds with hydrogen, oxygen, and other atoms like phosphorus, nitrogen, and sulfur.
The atom diagnostically associated with organic compounds is carbon. Carbon forms the backbone of organic molecules due to its ability to form strong covalent bonds with other carbon atoms and with other elements. The presence and arrangement of carbon atoms largely determine the properties and functions of organic compounds.
A phosphorus atom surrounded by four oxygen atoms is called a phosphate ion (PO4^3-). This arrangement forms a stable polyatomic ion commonly found in phosphates, which are essential components of many biological molecules and minerals.
