Overview of cycle between autotrophs and heterotrophs. A heterotroph (/ËhÉtÉrÉµtroÊf/ ; á¼ÏÎµÏÎ¿Ï heteros = another, different and ÏÏÎ¿ÏÎ® trophe = nutrition) is an organism that cannot fix carbon and uses organic carbon for growth.ost heterotrophs are chemoorganoheterotrophs (or simply organotrophs) who utilize organic compounds both as a carbon source and an energy source. The term heterotroph very often refers to chemoorganoheterotrophs.
Fumaric acid or trans-butenedioic acid is the chemical compound with the formula HO 2 CCH=CHCO 2 H. This white crystalline compound is one of two isomeric unsaturated dicarboxylic acids, the other being maleic acid.umaric acid has been used a food acidulant since 1946. It is approved for use as a food additive in the EU, USA and Australia and New Zealand. As a food additive, it is used as an acidity regulator and can be denoted by the E number E297.
What is Maleic Acid? Maleic Acid is also known as cis-butenedioic acid, toxilic acid, cis-1,2-Ethylenedicarboxylic acid. It is commercially available as the crystalline material or as an aqueous solution in water (40%). It may contain fumaric acid (0.1%) and water (less than 0.5%) as impurities.Uses: It is mainly used for making Maleate Salts of Bulk-Drugs like Pheneramine Maleate, Chloropheneramine Maleate and others.t may contain fumaric acid (0.1%) and water (less than 0.5%) as impurities.
