Unsaturated fatty acid has tendency to undergo rancidification due to the presence of double bond (σ: sigma bond
and π: pi bond) in oxidative catabolism in-vivo by oxidase enzyme and in-vitro due to air oxidation. Unsaturated
part undergoes reaction steps by Initiation, Propagation and Termination steps followed by free radical formation
in Initiation step, peroxide formation in Propagation step and hydro-peroxide step in Termination step which
produce obnoxious smell due to the formation of epoxide. Since blood is a biological fluid tissue so it produces
metallic smell of characteristic odour.
