Additionally, there is a third testis-specific Trx reductase, TrxR3, also known as thioredoxin glutathione reductase, which is primarily expressed in germ cells and contains a class I Grx domain [9] (see below)
NAD (Nicotinamide Adenine Dinucleotide) is a crucial coenzyme found in every cell of the body, responsible for energy production and cellular repair
