At the end of β-oxidation all carbons of a fatty acid are released in the form of

ACETYL-CoA, FADH

2  NADH  

 acetyl-CoA

Explanation: Beta oxidation of carbons of fatty acid acid molecules leads to the formation Acetyl-CoA, FADH and NADH.

The overall reaction for the process

Cn-acyl-CoA + FAD + NAD+

+ H

2O + CoA → Cn-2-acyl-CoA + FADH

2 + NADH + H+

+ acetyl-CoA.

formula of NADH is C21H27N7O14P2

formula of FADH is ‎C27H35N9O15P2.

Both NADH(Nicotinamide adenine dinucleotide) and FADH( Flavin adenine dinucleotide) are

formular for Acetyl CoA IS C23H38N7O17P3S.

Beta oxidation is a breakdown process taking place in living systems which catabolises the fatty acids through glycolysis or fermentation leading to the release of Acetyl CoA, NADH AND FADH2.
