DefinitionAn 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.

Roles Classification
Chemical Roles:
antioxidant  A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.
radical scavenger  A role played by a substance that can react readily with, and thereby eliminate, radicals.
Bronsted base  A molecular entity capable of accepting a hydron from a donor (Brønsted acid).
Biological Roles:
human metabolite  Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).
nutrient  A nutrient is a food component that an organism uses to survive and grow.
Saccharomyces cerevisiae metabolite  Any fungal metabolite produced during a metabolic reaction in Baker's yeast (Saccharomyces cerevisiae ).
immunosuppressive agent  An agent that suppresses immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-cells or by inhibiting the activation of helper cells. In addition, an immunosuppressive agent is a role played by a compound which is exhibited by a capability to diminish the extent and/or voracity of an immune response.
mouse metabolite  Any mammalian metabolite produced during a metabolic reaction in a mouse (Mus musculus).
glycine receptor agonist  An agonist that binds to and activates glycine receptors
Escherichia coli metabolite  Any bacterial metabolite produced during a metabolic reaction in Escherichia coli.
Applications:
immunosuppressive agent  An agent that suppresses immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-cells or by inhibiting the activation of helper cells. In addition, an immunosuppressive agent is a role played by a compound which is exhibited by a capability to diminish the extent and/or voracity of an immune response.
antipsychotic agent  Antipsychotic drugs are agents that control agitated psychotic behaviour, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect.
antineoplastic agent  A substance that inhibits or prevents the proliferation of neoplasms.
antihypertensive agent  Any drug used in the treatment of acute or chronic vascular hypertension regardless of pharmacological mechanism.
hypoglycemic agent  A drug which lowers the blood glucose level.
