FTL and nutritional disorder: FT, composed of 24 subunits of both ferritin heavy chain (FTH) and ferritin light chain (FTL), is regarded as a key factor implicated with iron homeostasis for the reason that it combines and segregates iron in the case of redundant iron importing to protect against oxidative stress, whereas it releases and transports iron when suffering iron deficiency (Kawabata, 2019).
