LIPIDS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A complex chain reaction that starts when lipids are exposed to oxygen
A
solidification
B
hydrogenation
C
autooxidation
D
melting point
Explanation: 

Detailed explanation-1: -Lipid oxidation is a highly complex set of free radical reactions between fatty acids and oxygen, which results in oxidative degradation of lipids, also known as rancidity.

Detailed explanation-2: -Lipid peroxidation is an oxidative chain reaction in which one lipid molecule after another becomes oxidized to the maximum possible extent or so as to form a lipid peroxide (i.e., a lipid molecule containing one or more O–O bonds).

Detailed explanation-3: -Autoxidation is therefore a fairly broad term and can encompass examples of photooxygenation and catalytic oxidation. The common mechanism is a free radical chain reaction, where the addition of oxygen gives rise to hydroperoxides and their associated peroxy radicals (ROO•).
