Below is the chemical reaction for the formation of calcium chloride: Calcium chloride salts can also form crystals based on these same ionic properties. Positive calcium ions can orient themselves so that they are close to the negative chloride ions in another molecule.
Neurofibrillary Tangles (NFTs) are aggregates of hyperphosphorylated tau protein that are most commonly known as a primary marker of Alzheimer's Disease.Their presence is also found in numerous other diseases known as tauopathies.ormation [edit]. Neurofibrillary tangles are formed by hyperphosphorylation of a microtubule-associated protein known as tau, causing it to aggregate, or group, in an insoluble form.
Amyloid Plaques and Neurofibrillary Tangles. The formation of amyloid plaques and neurofibrillary tangles are thought to contribute to the degradation of the neurons (nerve cells) in the brain and the subsequent symptoms of Alzheimer's disease.ne of the hallmarks of Alzheimer's disease is the accumulation of amyloid plaques between nerve cells (neurons) in the brain. Amyloid is a general term for protein fragments that the body produces normally.
