Abstract
Iron is an indispensable element in biological systems and is responsible for the function of many prosthetic groups, including oxygen transport, DNA synthesis, electron transport, and cellular proliferation and differentiation.In the brain, iron is an important component of enzyme systems required for DNA synthesis, respiratory chain, neurotransmitter synthesis and lipid metabolism. It is essential for a number of enzymes involved in neurotransmitter synthesis including tryptophan hydroxylase (serotonin), tyrosine hydroxylase (norepinephrine) and dopamine
