Salt compounds dissociate in aqueous solutions. This property is exploited in the process of salting out. When the salt concentration is increased, some of the water molecules are attracted by the salt ions, which decreases the number of water molecules available to interact with the charged part of the protein.

Stable isotope analysis of human and faunal hydroxyapatite can be used to indicate whether a diet was predominantly terrestrial or marine in nature (carbon, strontium); [40] the geographical origin and migratory habits of an animal or human (oxygen, strontium) [41] and to reconstruct past temperatures and climate shifts (oxygen).

The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body. [4]
S = solubility of the protein, B is idealized solubility, K is a salt-specific constant and I is the ionic strength of the solution, which is attributed to the added salt. = = z i is the ion charge of the salt and c i is the salt concentration. The ideal salt for protein precipitation is most effective for a particular amino acid composition ...
The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney. The renal vein (or kidney vein) carries the filtrated blood away from
Conservators will remove the soluble salt to make the object stable by using water with certain levels of chloride and ionization, only if the object is structurally sound. Removal of insoluble salts and stains : to remove insoluble salts and stains, conservators either use a mechanical method with picks and other tools or chemical treatment.

P11-4 is a self-assembling β-peptide. It builds a 3-D bio-matrix with binding sites for Calcium-ions serving as nucleation point for hydroxyapatite (tooth mineral) formation. The high affinity to tooth mineral is based on matching distances of Ca-ion binding sites on P11-4 and Ca spacing in the crystal lattice of hydroxyapatite.
