Aspergillic acid acetic acid gives a diketopiperazine. Hydrolysis with HBr yields a mixture of -leucine and -isoleucine. These reaction schemes can be seen below: Aspergillic acid Aspergillic acid is an organic chemical compound with the molecular formula CHNO. It has a pale yellow crystalline appearance. Aspergillic acid is most commonly known as an antibiotic and antifungal agent that is derived from certain strains of the fungus "Aspergillus flavus". In 1940 Edwin C. White and Justina H. Hill discovered that a fungal strain of "Aspergillus flavus" growing in a surface culture on a tryptone-salt was capable of producing a bactericidal filtrate. It has
Orthocarbonic acid to be observed. However, theoretical studies suggest that NaCO might be stable. The tetravalent moiety CO is found in stable organic compounds; they are formally esters of orthocarbonic acid, and therefore are called orthocarbonates. For example, Tetraethoxymethane can be prepared by the reaction between chloropicrin and sodium ethoxide in ethanol. Polyorthocarbonates are stable polymers that might have applications in absorbing organic solvents in waste treatment processes, or in dental restorative materials. The explosive trinitroethylorthocarbonate possesses a orthocarbonate core. Orthocarbonic acid Orthocarbonic acid (methanetetrol) is the name given to a hypothetical compound with the chemical formula HCO or C(OH). Its molecular
