Ornithine is an amino acid produced in the urea cycle by the splitting off of urea from arginine. It is a central part of the urea cycle, which allows for the disposal of excess nitrogen. Ornithine is also a precursor of citrulline and arginine. Arginine stimulates the pituitary release of growth hormone. Burns or other injuries affect the state of arginine in tissues throughout the body. As de novo synthesis of arginine during these conditions is usually not sufficient for normal immune function, nor for normal protein synthesis, ornithine may have immunomodulatory and wound-healing activities under these conditions (by virtue of its metabolism to arginine).

Lauric acid, or dodecanoic acid, is the main acid in coconut oil and in palm kernel oil, and is believed to have antimicrobial properties. The detected values of half maximal effective concentration (EC(50)) of lauric acid on P. acnes, S. aureus, and S. epidermidis growth indicate that P. acnes is the most sensitive to lauric acid among these bacteria. In addition, lauric acid did not induce cytotoxicity to human sebocytes. This data highlight the potential of using lauric acid as an alternative treatment for antibiotic therapy of acne vulgaris. Lauric acid is used in the manufacture of soaps, detergents, cosmetics, and lauryl alcohol.

Behenic acid is a saturated fatty acid that is derived from the oil extracts of plants and used as a component of conditioning agents. Behenic acid is also a part of a novel complex of lipophilic ingredients developed for the treatment of dry skin. The properties of behenic acid were studied in comparison to others fatty acids and it was found that behenic acid does not inhibit the UDP-glucuronosyltransferase (UGT) 1A1 enzyme. The high levels of behenic acid in patients with low-grade glial tumors is an important indicator of the persistence of tissue integrity and tissue resistance. Therefore, behenic acid levels can be a prognostic factor in glial tumors.

Cetyl myristoleate (CMO) is the hexadecyl ester of myristoleic acid. Whereas myristoleic acid is commonly found in fish oils, whale oils, and dairy butter, CMO is known to exist only naturally in sperm whale oil and in a small gland in the male beaver. Cetyl myristoleate is effective in alleviating knee pain in persons with mild degree arthritis of the knee joint.

Cetyl oleate is a cosmetic emollient ester

2,5-Dimethyl-N-Phenyl-3H-diazaphophol-4-imine is a quinonoid tautomer of GABAA and GABAB agonist progabide. According to quantum mechanical calculations, a quinonoid form is predominant in polar solvents, while aromatic tautomer is prevalent in apolar solvents. Progabide is a prodrug of gamma-aminobutyric acid and was investigated for the treatment of epilepsy, Parkinson's disease, schizophrenia, clinical depression, anxiety disorder, and other diseases. Progabide was marketed in France by Sanofi Aventis under tradename Gabrene for use in monotherapy and also as adjunctive therapy for generalized tonic-clonic, myoclonic, partial seizures, and for Lennox‐Gastaut syndrome, in both children and adults.

Doconexent (Docosahexaenoic acid, DHA) is an omega-3 fatty acid that is a primary structural component of the human brain, cerebral cortex, skin, and retina. DHA is widely used as a food supplement, and is beleived to support healthy brain development in young childred, prevent cardiovascular disease and cognitive decline during Alzheimer's disease. Most of these claims, however, were not supported by clinical trials. DHA spray is used as a tanner.

Carnosine is a dipeptide composed of the amino acids beta-histidine and l-alanine. It is widely present in muscle and brain tissues. It possesses strong and specific antioxidant properties, protects against radiation damage, and promotes wound healing. The antioxidant mechanism of carnosine is attributed to its chelating effect against metal ions, superoxide dismutase (SOD)-like activity, ROS and free radicals scavenging ability. In addition, was shown, that carnosine significantly protects against TCA-induced liver carcinogenesis in rats, through its antioxidant, antinutritive, and anti-inflammatory effects, and induction of apoptosis. It also may be a therapeutic agent against Parkinson's disease. Experiments on animal have shown the sepsis healing therapeutic potential of carnosine.

Creatine is an amino acid that occurs in vertebrate tissues and in urine. It is synthesized mainly in the liver from three different amino acids: arginine, glycine, and methionine. In skeletal muscles, which store 95% of it, creatine generally occurs as phosphocreatine. The rest is stored in the brain, heart, and testes. Creatine functions as part of the cell's energy shuttle. It is excreted as creatinine in the urine.
