General description
Zein is a prolamine and an alcohol soluble protein present in maize endosperm cells.[1][2] Zein is a 20kDa structural protein and is encoded by the gene mapped on the short arm of maize chromosome 7.[2] This protein lacks essential amino acids, such as lysine and tryptophan. Therefore, it has a poor nutritional value.[1]
