Split and merge into it. Answer by FarhatAzim. Confidence votes 260. a substance that is formed in a chemical reaction is called a product. =) After a chemical reaction, new chemicals are formed. For an example:- NaOH + HCl = NaCl + HOH(H2O). Chemical substances are formed in chemical reactions.plit and merge into it. Answer by FarhatAzim.

Eicosanoids are an extremely complex group of organic molecules that have a number of functions in the body. Derived from fatty acids, they are signaling molecules, with a short half-life, that control a number of different pathways.icosanoids are an extremely complex group of organic molecules that have a number of functions in the body.

Leukotrienes are a family of eicosanoid inflammatory mediators produced in leukocytes by the oxidation of arachidonic acid by the enzyme arachidonate 5-lipoxygenase. As their name implies, leukotrienes were first discovered in leukocytes, but have since been found in other immune cells.n cells that express LTC4 synthase, such as mast cells and eosinophils, LTA 4 is conjugated with the tripeptide glutathione to form the first of the cysteinyl-leukotrienes, LTC 4. Outside the cell, LTC 4 can be converted by ubiquitous enzymes to form successively LTD 4 and LTE 4, which retain biological activity.
