Alpha-linolenic acid (ALA), an 18-carbon omega-3 essential fatty acid, is the precursor of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). ALA cannot be synthesized by humans and therefore must be entirely acquired from exogenous sources. Evidence for the essentiality of ALA was first provided by a study showing that ALA supplementation reversed the abnormal neurologic signs observed in a 6-year-old girl who suffered from sensory loss and visual complications. Most of the ALA is catabolized via beta-oxidation for energy generation, and a small proportion of it undergoes conversion to produce another two potent members of omega-3 PUFA family: EPA and DHA. Delta 6 desaturase (D6D) enzyme is responsible the conversion of ALA to DHA. Although not conclusive, it was suggested, that the benefits associated with ALA seem to stem mainly from EPA and DHA, and as major consequence of ALA deficiency it appears that EPA and DHA are not adequately produced.

Triphosphoric acid (also tripolyphosphoric acid), a condensed form of phosphoric acid. Sodium tripolyphosphate (STPP) is used as a preservative for poultry, meat, and seafood; it’s added to processed cheeses as an emulsifier and is used in food industry as an E number E451.

Maleic acid monosodium salt. Used in water soluble polymers preparation.

Diammonium sulfite monohydrate (Ammonium sulfite monohydrate) has a wide use of applications, such as hair straightening or waving agents, as an ingredient in carmel food coloring, as well as an reducing agent in photography. Other applications include lubricants for cold metal working and blast furnace linings. It is considered safe as used in cosmetic formulations.

Pipemidic Acid is a quinolone antibacterial agent. It’s used in the treatment of urinary tract infections, recidive cystitis, prolongation of the therapy of pyelonephritis (prolonged therapy at patients with tendency to recidives. It belongs to DNA Gyrase inhibitor pharmacological group on the basis of mechanism of action and also classified in Antibacterial pharmacological group. Pipemidic acid is contraindicated at conditions of proved hypersensitivity, severe renal and hepatic insufficiency, cirrhosis of the liver, porphyria, diseases of the central nervous system (epilepsy and neurological conditions with low level for convulsions). Pipemidic acid is contraindicated at children and adolescents at growing phase.

Arsanilic acid, also known as aminophenyl arsenic acid or aminophenyl arsonic acid, is an organoarsenic compound first reported in 1863 by Antoine Béchamp. Arsanilic acid is a crystalline powder introduced medically in the late 19th century as Atoxyl, its sodium salt was used by injection in the early 20th century as the first organic arsenical drug, but it was soon found prohibitively toxic for human use. Arsanilic acid saw long use as a veterinary feed additive promoting growth and to prevent or treat dysentery in poultry and swine. In 2013, its approval by US government as an animal drug was voluntarily withdrawn by its sponsors. Still sometimes used in laboratories, Arsanilic acid's legacy is principally through its influence on Paul Ehrlich in launching the chemotherapeutic approach to treating infectious diseases of humans.

Ammonium hexafluorosilicate is a white crystalline solid. Corrodes aluminum. Used as a disinfectant, in etching glass, metal casting, and electroplating. Ammonium hexafluorosilicate is useful for the treatment of dentin hypersensitivity, since ammonium hexafluorosilicate induced calcium phosphate precipitation from the saliva; therefore, it has a continuous effect on dentin tubules occlusion under a simulated oral environment. Ammonium hexafluorosilicate has been applied to arrest caries without discoloration. The major use of sodium hexafluorosilicate and fluorosilicic acid is as fluoridation agents for drinking water. Sodium hexafluorosilicate has also been used for caries control as part of asilicophosphate cement, an acidic gel in combination with monocalcium phosphate monohydrate,and a two-solution fluoride mouth rinse. Both chemicals are also used as a chemical intermediate (raw material) for aluminum trifluoride, cryolite (Na3AlF6), silicon tetrafluoride,and other fluorosilicates and have found applications in commercial laundry. Other applications for sodium hexafluorosilicate include its use in enamels/enamel frits for china and porcelain, in opalescent glass, metallurgy (aluminum and beryllium), glue, ore flotation, leather and wood preservatives, and in insecticides and rodenticides. It has been used in the manufacture of pure silicon, as a gelling agent in the production of molded latex foam, and as afluorinating agent in organic synthesis to convert organodichlorophosphorus compounds to the corresponding organodifluorophosphorus compound. In veterinary practice, external applicationof sodium hexafluorosilicate combats lice and mosquitoes on cattle, sheep, swine, and poultry, and oral administration combats roundworms and possibly whipworms in swine and prevents dental caries in rats. Apparently, all pesticidal products had their registrations cancelled or they were discontinued by the early 1990s

Dibunate (also known as Becantex, Becantyl, Linctussal, L-1633, and described as the 2,6-isomer or the 2,7-isomer) is an antitussive oral medication that was used in many counties all over the world. The current marketing status of the drug is unknown and is supposed to be "discontinued".

Alpha-ketoglutarate (AKG), an endogenous intermediary metabolite in the Krebs cycle, is a molecule involved in multiple metabolic and cellular pathways. As an intermediate of the tricarboxylic acid cycle, AKG is essential for the oxidation of fatty acids, amino acids, and glucose. Extracellular AKG is a significant source of energy for cells of the gastrointestinal tract. As a precursor for the synthesis of glutamate and glutamine in multiple tissues (including liver, skeletal muscle, heart, brain, and white adipose tissue), AKG bridges carbohydrate and nitrogen metabolism for both conservation of amino acids and ammonia detoxification. Additionally, emerging evidence shows that AKG is a regulator of gene expression and cell signaling pathways (including the mammalian target of rapamycin and AMPactivated protein kinase). Thus, AKG is an attractive dietary supplement in animal and human nutrition to improve cellular energy status, immunity, and health.AKG can decrease protein catabolism and increase protein synthesis to enhance bone tissue formation in the skeletal muscles and can be used in clinical applications. In addition to these health benefits, a recent study has shown that AKG can extend the lifespan of adult Caenorhabditis elegans by inhibiting ATP synthase and TOR. Orally, AKG is used for kidney disease, gastrointestinal disorders, bacterial overgrowth, intestinal toxemia, liver dysfunction, and chronic candidiasis. It is also used for improving peak athletic performance, improving amino acid metabolism in hemodialysis patients, and cataracts. Intravenously, AKG is used for preventing ischemic injury during heart surgery, improving renal blood flow after heart surgery, and preventing muscle protein depletion after surgery or trauma.

Pangamic acid (6-O-(dimethylaminoacetyl)-D-gluconic acid) has been detected 1938 and described as a natural, universally occurring substance with multiple biological and medical functions. In this respect pangamic acid has been worldwide on the market since decades as a drug stimulating cellular respiration. In addition to the natural pangamic acid, diisopropylammonium dichloroacetate (DIPA), a synthetic product not found in biological material, is on the market requesting similar biological functions. Pangamic acid is the name given to a product originally claimed to contain D-gluconodimethyl aminoacetic acid, which was obtained from apricot kernels and later from rice bran. It is also referred to as vitamin B15, but pangamic acid is not generally recognized as a vitamin. Despite serious safety concerns, pangamic acid is used for improving exercise endurance; treating asthma and related diseases, skin conditions including eczema, lung problems, painful nerve and joint conditions, cancer, and arthritis; improving the oxygenation of the heart, brain, and other vital organs; and “detoxifying” the body. It is also used for treating alcoholism, hangovers, and fatigue; protecting against urban air pollutants; extending cell life; strengthening the immune system; lowering bloodcholesterol levels; and assisting in hormone regulation. Since there is no standard identity for the chemicals in pangamic acid, how it might work is unknown. Although pangamic acid is also called vitamin B15, there is no research that shows it is required by the body, as the term “vitamin” would suggest. The United States Food and Drug Administration has recommended seizing any chemicals advertised as pangamic acid and restraining the importation and interstate shipment of pangamic acid on the grounds that pangamic acid and pangamic acid products are unsafe for use and have no known nutritional properties
