Chapter 11. Calcium

Net absorbed calcium is the difference between dietary calcium and faecal calcium and is numerically the same as true absorbed calcium minus endogenous faecal calcium. At zero calcium intake, all the faecal calcium is endogenous and represents the digestive juice calcium which has not been reabsorbed; net absorbed calcium at this intake is therefore negative to the extent of about 200 mg (5 …

Calcium - Wikipedia

face-centred cubic (fcc) Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium.

Native metal - Wikipedia

Over geological time scales, very few metals can resist natural weathering processes like oxidation, so mainly the less reactive metals such as gold and platinum are found as native metals. The others usually occur as isolated pockets where a natural chemical process reduces a common compound or ore of the metal, leaving the pure metal behind as small flakes or inclusions.

Sodium Alginate - an overview | ScienceDirect Topics

It is an anionic polyelectrolyte with a backbone of (1–4) linked β- d -mannuronic acid (M units) and α- l -guluronic acid (G units). It can form irregular patterns of GG, MG, and MM blocks ( Fig. 3.2 b). The G-blocks of alginate are known to participate in intermolecular crosslinking with divalent calcium ions.

Complexation - an overview | ScienceDirect Topics

If the metal is paramagnetic (e.g., Fe 3+, Co 2+, Ni 2+, Cu 2+ ), an increase in intersystem crossing from the S 1 state to the T 1 state of the aromatic ligand takes place, which causes a decrease in fluorescence. Another phenomenon that operates in metal complexation to prevent fluorescence is the heavy atom effect.
