Таурин

Химические свойства

Taurine is a naturally occurring amino acid with a bitter taste and sharp flavor. It is a nonessential amino acid by definition because the body can synthesize it from methionine and cysteine.

Вхождение

Reported found in beef, black beans, chicken, chick peas, clams, cod, fish, lamb, milk, octopus, oysters, pistachios, pork, scallops, shrimp and other natural sources.

Использование

Taurine is an organic acid found in animal tissues and is a major constituent of bile. Taurine has many biological roles such as conjugation of bile acids, antioxidation, osmoregulation, membrane stabilization and modulation of calcium signaling. It is an amino acid nutritional supplement that is used to treat taurine-deficiency diseases such as dilated cardiomyopathy, a type of heart disease.

Определение

ChEBI: Taurine is an amino sulfonic acid that is the 2-amino derivative of ethanesulfonic acid. It is a naturally occurring amino acid derived from methionine and cysteine metabolism. An abundant component of fish- and meat-based foods, it has been used as an oral supplement in the treatment of disorders such as cystic fibrosis and hypertension. It has a role as a human metabolite, an antioxidant, a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a glycine receptor agonist, a nutrient and a radical scavenger. It is a conjugate acid of a 2-aminoethanesulfonate. It is a tautomer of a taurine zwitterion.

Общее описание

Taurine, which has chemistry similar to other amino acids, is important in several of the body's metabolic processes. Taurine is thought to have antioxidant properties. But little is known about the effects of long-term supplemental taurine use.

Реакции воздуха и воды

Water soluble.

Профиль реактивности

Taurine is an amino acid found in combination with bile acids [Hawley].

Опасность

Toxic by ingestion.

Угроза здоровью

ACUTE/CHRONIC HAZARDS: Taurine evolves highly toxic fumes when heated to decomposition, and may cause irritation on contact.

Пожароопасность

Flash point data are not available for Taurine, but Taurine is probably combustible.

Биологическая активность

One of the most abundant free amino acids in the brain. A partial agonist at the inhibitory glycine receptor.

Профиль безопасности

Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of SOx and NOx.
