HYDROXYPROLINE, a hydroxylated form of the imino acid proline, is a major component of the protein collagen. For this reason, HYDROXYPROLINE content in biological fluids is used as a parameter of collagen catabolism, especially bone resorption or tissue degradation. A deficiency in ascorbic acid can result in impaired HYDROXYPROLINE formation.

Galactose, a monosaccharide sugar, is a key source of energy and is an important compound for early human development. Galactose is present in dairy products, the pectin of some fruits, vegetables, and some herbs. Children get most of their dietary galactose from milk. D-galactose is freely available in health food stores and is promoted for stimulating the immune system and improving gut motility in healthy individuals. Galactose as a part of food supplement participates in phase II of clinical trials for congenital disorders of glycosylation (CDG) patients. CDG is a group of more than 130 inborn errors of metabolism affecting N-linked, O-linked protein and lipid-linked glycosylation. In addition, monosaccharide is used in clinical trials phase I in patients with focal segmental glomerulosclerosis (FSGS), where the galactose lowers the level of a circulating factors that increase glomerular permeability to albumin in patients with resistant FSGS.

Methyl chloride, also called chloromethane, mainly is used as a refrigerant. It’s known, that methyl chloride permeates through human epidermis when exposed at high atmospheric concentrations within relatively short timeframes. Recently published article has shown that chlorinated methyl group could be formed in humans, that might be an important target compound in future medical diagnostic programs.

HYDROXYETHYLETHYLENEDIAMINETRIACETIC ACID (HEDTA) is used in cosmetics and care products. It’s a chelating agent, which in combination with selenium was effective in reducing the concentration of Al and level of DNA damage. In addition, experiments with rodents have shown that combination of HEDTA and propolis preserved histological features, mitigated oxidative stress and improved liver, kidney, and brain functions more profoundly.

Glyceryl 1-oleate (1-O-Oleyl-rac-glycerol, Glyceryl oleate, Monoolein), is a surfactant that releases free glycerol and oleic acid upon hydrolysis. Monoolein has been used in liquid crystal studies and research shows that in the presence of monoolein, the penetration of the drug cisplatin (sc-200896) is doubled. Monoolein (1-Oleoyl-rac-glycerol) is used in the development of monoolein-based nanoparticulate liquid dispersions as possible vehicles for drug delivery. Glyceryl oleate is the monoester of glycerin and oleic acid. It's part of the hair lipids and skin lipids and has re-fating properties. Used as emulsifier and nonionic co-surfactant in various skin and hair care products. Creates water-in-oil emulsions (HLB value 3.5) but can also be used as a co-emulsifier and thickener for oil-in-water formulations. Add to oil/emulsifier phase of formulas. Typical use level: 0.5-3%. If used in surfactant systems, typical use level is 0.5-1% which should still keep shampoos clear and transparent.

Camphor, -/- is a bicyclic monoterpene ketone found widely in plants, especially Cinnamomum camphora. Camphor has anti-inflammatory and analgesic properties. It is also used for its aromatic properties as an insect repellant and in embalming fluids. It is used topically as a skin antipruritic (itch relief) and as an anti-infective agent.

Bicisate hydrochloride is a ligand that is used to form a complex with technetium. Tc99m Bicisate forms a stable, lipophilic complex that crosses intact cell membranes and blood brain barrier by passive diffusion. The amount of tc99m bicisate is stable in the brain until about 6 hours. Tc99m bicisate is indicated as an adjunct to conventional CT or MRI imaging in the localization of stroke in patients in whom stroke has already been diagnosed.
