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
Nonanoic acid nonanoic acid, such as methyl nonanoate, are used as flavorings. Nonanoic acid is also used in the preparation of plasticizers and lacquers. The derivative 4-nonanoylmorpholine is an ingredient in some pepper sprays. The ammonium salt of nonanoic acid, ammonium nonanoate, is an herbicide. It is commonly used in conjunction with glyphosate, a non-selective herbicide, for a quick burn-down effect in the control of weeds in turfgrass. Nonanoic acid may be more potent than valproic acid in treating seizures. Moreover, in contrast to valproic acid, nonanoic acid exhibited no effect on HDAC inhibition, suggesting that it is unlikely to show HDAC
