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.
The buildup of two abnormal structures in the brain (amyloid plaques and neurofibrillary tangles) is common in AD and may be part of the cause. Amyloid plaques are clumps of beta-amyloid. Beta-amyloid is a piece of a protein that is found in the normal brain.
