Hydrolytic rancidity refers to the odor that develops when triglycerides are hydrolyzed and free fatty acids are released. This reaction of lipid with water may require a catalyst (such as a lipase , [ 6 ] or acidic or alkaline conditions) leading to the formation of free fatty acids and glycerol .

The Virgo interferometer is a large-scale scientific instrument near Pisa, Italy, for detecting gravitational waves.The detector measures minuscule length variations in its two 3-kilometre (1.9-mile) arms induced by the passage of gravitational waves.
The common mechanism is a free radical chain reaction, where the addition of oxygen gives rise to hydroperoxides and their associated peroxy radicals (ROO•). [5] Typically, an induction period is seen at the start where there is little activity; this is followed by a gradually accelerating take-up of oxygen, giving an autocatalytic reaction ...
The peroxide value is defined as the amount of peroxide oxygen per 1 kilogram of fat or oil. Traditionally this was expressed in units of milliequivalents, although in SI units the appropriate option would be in millimoles per kilogram (N.B. 1 milliequivalents = 0.5 millimole; because 1 mEq of O 2 =1 mmol/2 of O 2 =0.5 mmol of O 2, where 2 is valence).
The cases of Urooj Khan, lottery winner of Chicago, and Autumn Klein, doctor of Pittsburgh, both fit these characteristics, since neither patient exhibited cyanide poisoning symptoms, yet both appeared to have suffered heart attacks, with Urooj Khan's blocked arteries noted at autopsy [7] and Autumn Klein's evidence for heart abnormalities ...
Free radical mechanisms in tissue injury. Lipid peroxidation induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination). Antioxidants play a crucial role in mitigating lipid peroxidation by neutralizing free radicals, thereby halting radical chain reactions. Key antioxidants include vitamin C and vitamin E. [8]
