Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the name of the reaction that causes the fatty acids to join to the glycerol?
A
Condensation
B
Hydrolysis
C
Ester
D
glycosidic
Explanation: 

Detailed explanation-1: -Saponification can be defined as a “hydration reaction where free hydroxide breaks the ester bonds between the fatty acids and glycerol of a triglyceride, resulting in free fatty acids and glycerol, ‘’ which are each soluble in aqueous solutions.

Detailed explanation-2: -Fatty acids are activated by reaction with CoA to form fatty acyl CoA. The reaction normally occurs in the endoplasmic reticulum or the outer mitochondrial membrane. This is an ATP-requiring reaction, yielding AMP and pyrophosphate (PPi).

Detailed explanation-3: -Lipolysis. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm.
