Vanillin (4-hydroxy-3-methoxybenzaldehyde), a pleasant smelling organic aromatic compound, is widely used as a flavoring additive in food, beverage, cosmetic and drug industries. It is reported to cross the blood brain barrier and also displayed antioxidant and neuroprotective activities. Vanillin is a natural substance widely found in many plant species and often used in beverages, foods, cosmetics, and pharmaceutical products. Antioxidant and anticancer potential have been described for this compound. Vanillin has been classified as a bioantimutagen and is able to inhibit mutagenesis induced by chemical and physical mutagens in various cell systems. Vanillin, a selective agonist of TRPV1, has been shown to attenuate i.c.v. STZ and AlCl3+d-galactose induced experimental Alzheime's disease (AD).

Lactose is the most important carbohydrate in the milk of most species. Its biosynthesis takes place in the mammary gland. The molecular structures of α- and β -lactose differ in the orientation of a hydrogen- and a hydroxyl group on carbon atom no.1 in the glucose moiety. Both forms change into one another continuously. At room temperature, the equilibrium results in a ratio of about 40% α-lactose and 60% β-lactose. The fact that two forms of lactose exist which differ in molecular structure has profound effects on various properties of lactose such as crystallization behavior, crystal morphology, solid-state properties, and solubility. The intestine does not actively absorb lactose unless it is split into its two-monosaccharide components, i.e. glucose and galactose. This hydrolysis of lactose is affected by the enzyme lactase, which is produced by the epithelium cells in the brush-border of the small intestine. Thus, the capacity of mammals to digest lactose is dependent on the lactase activity in the intestine. The maximum activity of the enzyme occurs shortly after birth and declines during the weaning period, after which it remains at a relatively constant level. Genetically determined factors governing residual lactase activity also exist. Individuals having low lactase activity are called lactose malabsorbers. Lactose intolerance is a condition in which people have symptoms due to the decreased ability to digest lactose. The principal symptom of lactose intolerance is an adverse reaction to products containing lactose (primarily milk), including abdominal bloating and cramps, flatulence, diarrhea, nausea, borborygmi, and vomiting (particularly in adolescents). These appear one-half to two hours after consumption.

Fructose, or fruit sugar, is a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. At a commercial scale, fructose is often derived from sugar cane, sugar beets, and maize. Fructose is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream. A growing body of research suggests that diet high in fructose may be contributing to incidences of obesity, insulin resistance, and diabetes.

Cerous iodide is a salt of lanthanide metal cerium (III) and iodide ion. In 1920s solution of cerous iodide for intravenous injection (called "introcid") was used as an antimicrobial agent for treating puerperal fever. It has shown prophylactic activity against sepsis, and was explored for its antineoplastic properties in patients with lymphogranulomatosis or inoperable solid tumors. According to the clinical reports, it has been applied with remarkable benefit, as indicated by tumor shrinkage and improved quality of life in several cases of locally advanced or metastatic tumors of different origin.

Urethane (Ethyl carbamate) is is an ethyl ester of carbamic acid, that has been found in many fermented food products and alcoholic beverages such as cheese, bread, yogurt, wine, whiskey, soya sauce etc. An in vitro study indicated that Urethane has a potential to inhibit the growth of bacteria, plant tissue, and rat carcinoma. Urethane has been used for many years as an antineoplastic agent for medical purposes but this application ended after it was discovered to be carcinogenic in 1943. Urethane can produce long-lasting anesthesia without affecting blood gases or blood pressure, it has been used in acute studies. In earlier studies, Urethane was also used as a co-solvent for water-insoluble analgesic and sedative drugs in Japan. By US FDA regulations, ethyl carbamate has been withdrawn from pharmaceutical use. However, small quantities of ethyl carbamate are also used in laboratories as an anesthetic for animals.

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.
