text: Zinc is found in high concentration in brain tissue and is important in neurotransmission across glutamatergic synapses.14 Zinc ions have been associated with the formation of beta-amyloid plaques that are characteristic of Alzheimer disease, but direct causality has not been established.11, 14, 15 Specific zinc-binding sites on the amyloid plaques have been demonstrated16 and acceleration of aggregation of amyloid peptides by zinc has been suggested.1
text: Zinc is hypothesized to play a role in the development of AMD for several reasons: (1) zinc is found at high concentrations in the part of the retina affected by AMD, (2) retinal zinc content has been shown to decline with age, and (3) the activities of some zinc-dependent retinal enzymes have been shown to decline with age.
text: Zinc is an essential trace element in the human body, where it is found in high concentration in the red blood cells as an essential part of the enzyme carbonic anhydrase, which promotes many reactions relating to carbon dioxide metabolism.
