Flavin adénine dinucléotide

The Flavine adénine dinucléotide (figure 1) is a Coenzyme of oxydoreduction deriving from the Riboflavine. This coenzyme is associated with the enzymes of the class of the Oxydoréductase S to which it is bound by a covalent bond: it is a prosthetic grouping.

This coenzyme is in particular used by the Flavoprotéine S of complex II of the respiratory chain mitochondriale: Glycerol 3-P déshydrogénase, AcylCoA déshydrogénase, Succinate déshydrogénase.

The redox cell is the following: $FAD\; \backslash \; leftrightarrow\; FADH\_\; \{2\}$

Structure

Flavin - Ribitol - Phosphate - Phosphate - Ribose - Adénine

NB: Core Flavin (drift of the isoalloxazine)

Ribitol (linear ose in C5)
