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.
Closely related to pili are structures called fimbriae (singular: fimbria). These are short, filamentous structures, present in large numbers that aid in cell adherence to surfaces. A bacterium that has fimbriae is usually covered with short hair-like fibers.
