Cyanobacteria such as these carry out photosynthesis.Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.. Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide) to organic compounds.

Mellitic acid, which contains no C-H bonds, is considered a possible organic compound in Martian soil. [15] Terrestrially, it, and its anhydride, mellitic anhydride, are associated with the mineral mellite (Al 2 C 6 (COO) 6 ·16H 2 O). A slightly broader definition of the organic compound includes all compounds bearing C-H or C-C bonds.
The main academic full-text databases are open archives or link-resolution services, although others operate under different models such as mirroring or hybrid publishers. . Such services typically provide access to full text and full-text search, but also metadata about items for which no full text is availa

The Database Issue of NAR is freely available, and categorizes many of the public biological databases. A companion database to the issue called the Online Molecular Biology Database Collection lists 1,380 online databases. [15] Other collections of databases exist such as MetaBase and the Bioinformatics Links Collection. [16] [17]

Biology and its subfields of biochemistry and molecular biology study biomolecules and their reactions. Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human body's mass. But many other elements, such as the various biometals, are also present in small amounts.
