Nucleic acid notation Nucleic acid notation The nucleic acid notation currently in use was first formalized by the International Union of Pure and Applied Chemistry (IUPAC) in 1970. This universally accepted notation uses the Roman characters G, C, A, and T, to represent the four nucleotides commonly found in deoxyribonucleic acids (DNA). Given the rapidly expanding role for genetic sequencing, synthesis, and analysis in biology, researchers have been compelled to develop alternate notations to further support the analysis and manipulation of genetic data. These notations generally exploit size, shape, and symmetry to accomplish these objectives. Degenerate base symbols in biochemistry are an IUPAC
Benzenesulfonic acid sometimes called alkaline fusion, initially affords the phenoxide salt: The process has been largely displaced by the Hock process, which generates less waste. Benzensulfonic acid is commonly used as the active ingredient in laundry detergent used in clothes washing machines. Benzenesulfonic acid is often used to convert to other specialty chemicals. A variety of pharmaceutical drugs are prepared as benzenesulfonate salts and are known as besilates (INN) or besylates (USAN). In a diluted form, it is also used as a polymer remover stripping agent. Benzenesulfonic acid Benzenesulfonic acid (conjugate base benzenesulfonate) is an organosulfur compound with the formula CHOS. It
