In what form is aluminum toxic?
Aluminium’s free metal cation, Alaq(3+), is highly biologically reactive and biologically available aluminium is non-essential and essentially toxic.
Is aluminum ion toxic?
The Al ion has no physiological role in metabolic processes (Exley and House, 2011) but it can be a metallic toxicant to humans and animals (Becaria et al., 2002) when there is high body burden of the metal after natural or unnatural exposure (Exley, 2013).
What are the properties of glutamate?
Glutamic acid

Is aluminum a neurotoxin?
Aluminium is neurotoxic. Its free ion, Al(3+) (aq), is highly biologically reactive and uniquely equipped to do damage to essential cellular (neuronal) biochemistry. This unequivocal fact must be the starting point in examining the risk posed by aluminium as a neurotoxin in humans.
How does aluminium get into the brain?
There have been three routes by which aluminum could enter the brain from systemic circulation or the site of absorption. Aluminum fluxes into brain across the blood-brain barrier (BBB), the choroid plexuses and the nasal cavity.
How does glutamate affect the brain?
Glutamate is an excitatory neurotransmitter with several types of receptors found throughout the central nervous system, and its metabolism is important to maintaining optimal levels within the extracellular space. As such, it is important to memory, cognition, and mood regulation.
Is glutamine harmful?
While uncommon, high quantities of glutamine can cause some side effects that require a doctor’s attention, including blood in urine, changes in skin color, lower back pain, fast heartbeat, dizziness, or rash. Introducing a glutamine supplement to your diet may cause some mild side effects.
Does aluminum cause neurological problems?
Aluminum is a ubiquitous neurotoxin highly enriched in our biosphere, and has been implicated in the etiology and pathology of multiple neurological diseases that involve inflammatory neural degeneration, behavioral impairment and cognitive decline.
How much aluminum is in the brain?
The nature of the aluminium data for the 60 human brains, range 0.01–33.00 μg/g dry wt., confirmed that which was already suspected, the focal as opposed to homogenous distribution of aluminium in human brain tissue [8].
What happens when you have too much glutamate?
At high concentrations, glutamate can overexcite nerve cells, causing them to die. Prolonged excitation is toxic to nerve cells, causing damage over time. This is known as excitotoxicity. Researchers are studying therapies that attempt to inhibit glutamate activity for the treatment of ALS.
