Gallium
Discovered in 1875, gallium is a trivalent metal that shares certain chemical characteristics with Fe 3+, Al3+ and In3+. An important property of gallium is its high affinity binding to transferrin, the iron transport protein in the circulation. Approximately one third of transferrin in blood is occupied by iron, leaving the remainder free to bind and transport gallium to cells that display transferrin receptors. In support of this mechanism is the finding that during radiogallium tumor imaging (Ga-67 scanning) in patients, Ga-67 in the circulation is bound almost exclusively to transferrin. A recent study examining the distribution of nonradioactive gallium in the circulation after its gastrointestinal uptake from gallium maltolate (an oral formulation of gallium) has confirmed that it binds to transferrin
Tin
Tin is a trace element that is required in bone formation. It has the atomic symbol Sn, atomic number 50, and atomic weight 118.71. (PubChem). Experimental studies over the last decade have suggested an association between thymus immune and homeostatic function and exogenous tin. It has been hypothesized that the thymus gland synthesizes and secretes one or more tin bearing factors that enhance immune defenses against malignancy and retard the gradual loss of immune capacity with senescence. (PMID 2195720). Physiologically, it exists as an ion in the body. Inorganic tin salts are poorly absorbed and rapidly excreted in the faeces; as a result they have a low toxicity. Only about 5 per cent is absorbed from the gastrointestinal tract, widely distributed in the body, then excreted by the kidney. Some tin is deposited in lung and bone. Some tin salts can cause renal necrosis after parenteral doses. Mutagenic studies on metallic tin and its compounds have been negative. Long-term animal carcinogenic studies have shown fewer malignant tumors in animals exposed to tin than in controls. Human volunteers developed mild signs of toxicity with tin, given in fruit juices, at a concentration of 1400 mg per litre. The WHO 1973 permissible limit for tin in tinned food is 250 micrograms per kg. The adult daily intake of tin was about 17 mg per day in 1940, but it has now decreased to about 3.5 mg, due to improvements in technique of tinning with enamel overcoat and crimped lids to minimize exposure to tin and lead solder. (PMID 3291572). A trace element that is required in bone formation. It has the atomic symbol Sn, atomic number 50, and atomic weight 118.71. (PubChem). Tin is found in many foods, some of which are black-eyed pea, red beetroot, red bell pepper, and apple.
PC(DiMe(11,3)/DiMe(13,5))
PC(DiMe(11,3)/DiMe(13,5)) is a phosphatidylcholine (PC or GPCho). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphocholines can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PC(DiMe(11,3)/DiMe(13,5)), in particular, consists of one chain of 12,15-epoxy-13,14-dimethyleicosa-12,14-dienoic at the C-1 position and one chain of 14,17-epoxy-15-methyldocosa-14,16-dienoic at the C-2 position. The 12,15-epoxy-13,14-dimethyleicosa-12,14-dienoic moiety is derived from fish oil, while the 14,17-epoxy-15-methyldocosa-14,16-dienoic moiety is derived from fish oil. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. PCs can be synthesized via three different routes. In one route, choline is activated first by phosphorylation and then by coupling to CDP prior to attachment to phosphatidic acid. PCs can also synthesized by the addition of choline to CDP-activated 1,2-diacylglycerol. A third route to PC synthesis involves the conversion of either PS or PE to PC.

Sodium borohydride
Reducing agent used in the prepn. of modified hop extract. BH4? is an excellent ligand for metal ions. Such borohydride complexes are often prepared by the action of NaBH4 (or the LiBH4) on the corresponding metal halide, e.g. Zr(BH4)4.; Sodium borohydride is a particularly dangerous laboratory reagent. It is highly corrosive, and will cause burns upon contact with any area of the body. It is harmful if swallowed, inhaled or absorbed through the skin. It is highly flammable and will react with water.; Sodium borohydride is an odorless white to gray-white microcrystalline powder which often forms lumps. It is soluble in water, with which it reacts vigorously.; Sodium borohydride is highly reactive, and supports combustion. It is a flammable solid. It can ignite in air in the presence of an open flame, and will continue to burn as hydrogen is evolved. It can react with water and steam to produce hydrogen, which is flammable. An explosion can occur by spontaneous ignition of the gases released from a saturated solution of sodium borohydride in dimethylformamide at 17 °C.; Sodium borohydride, also known as sodium tetrahydroborate, has the chemical formula NaBH4. This white solid, usually encountered as a powder, is a specialty reducing agent used in the manufacture of pharmaceuticals and other organic and inorganic compounds. It is soluble in methanol and water, but reacts with both in the absence of base. Sodium borohydride is found in alcoholic beverages. Reducing agent used in the prepn. of modified hop extract
