Disodium aspartate is used in organic biosynthesis.

HYDROCHLORIC ACID is formed by dissolving hydrogen chloride gas in water. It is a strong corrosive acid that is commonly used as a laboratory reagent. Also, it constitutes the majority of gastric acid, the human digestive fluid. Skin contact with HYDROCHLORIC ACID can cause redness, pain, and severe skin burns. It may cause severe burns to the eye and permanent eye damage.

Linoleic acid is a naturally occurring omega-6 essential fatty acid, present in a variety of foods, including the oils. Linoleic acid is a precursor for arachidonic acid biosynthesis; on the first enzymatic step of the pathway involves delta-6-desaturase, which converts linoleic acid to gamma-lenolenic acid. Linoleic acid has beneficial effects on human skin and hair. Replacement of saturated fat with linoleic acid is advocated to improve serum lipoprotein profiles and reduce the risk of coronary artery disease. Linoleic acid was tested in clinical trilas as a possible remedy against multiple sclerosis.

Oleic acid is an unsaturated fatty acid that is the most widely distributed and abundant fatty acid in nature. It is used commercially in the preparation of oleates and lotions, and as a pharmaceutical solvent. Oleic acid occurs naturally in various animal and vegetable fats and oils. It is a component of the normal human diet as a part of animal fats and vegetable oils. Oleic acid may be responsible for the hypotensive (blood pressure reducing) effects of olive oil. Oleic acid has being shown to have a potential anticancer activity.

Acetone (or propanone) is the smallest and simplest ketone, which is used in cosmetic as a nail polish remover. Acetone is produced within the body because of the breakdown of stored fats and lipids as a source of energy. Such conditions as physical exercise and prolonged dieting, which lead to cleavage of fat within the body, may result in higher than average amounts of acetone in the bloodstream. The concentration of acetone in the environment doesn’t cause a neurotoxic, carcinogenic, or reproductive health hazard effect. In addition, experiments on rodents have shown that acetone possesses anticonvulsant properties.

Direct reduced iron is an alternative iron source produced by heating an iron ore. In nature, most of the iron has an oxidized form.

Cobalamin (vitamin B12) is a cobalt-containing, B complex vitamin. B12 group (cobalamins) consist of cyanocobalamin, hydroxocobalamin, methylcobalamin and cobalamid. Neither plants nor animals are independently capable of constructing vitamin B12. Only bacteria and archaea have the enzymes required for its biosynthesis. Therefore, humans must absorb it from food. Excellent sources of B12 are foods of ruminant origin, so dairy and meat products play an important role in efforts to meet the official daily B12 intake. Vitamin B12 deficiency can potentially cause severe and irreversible damage, especially to the brain and nervous system. Vitamin B12 is used to treat vitamin B12 deficiency, including pernicious anemia.

Sucrose is a disaccharide composed of glucose and fructose, and found in many plants and plant parts. Sucrose is often extracted and refined from either sugarcane or beet sugar for human consumption. Upon ingestion, sucrose is hydrolyzed in the small intestine by by sucrase to glucose and fructose. Sucrose is used as inactive ingredients in numerous drugs. In medicine, sucrose is used for pain relief in infants.

Pastaron (Urea) is a waste product of many living organisms, and is the major organic component of human urine. It is a very important starting material in a number of chemical syntheses, and is used on an industrial scale for the manufacture of fertilizers, pharmaceuticals, and resins. Urea is an osmotic diuretic similar to mannitol but more irritant. Applied topically, urea promotes hydration of keratin and mild keratolysis in dry skin. It increases water uptake by the stratum corneum and has an antipruritic effect. Pastaron is used to soften rough or dry skin caused by skin conditions such as eczema, psoriasis, keratosis, and others.
