ChEBI

A molecular entity capable of donating a hydron to an acceptor (Bronsted base).

A tightly bound, specific nonpolypeptide unit in a protein determining and involved in its biological activity.

Any mammalian metabolite produced during a metabolic reaction in a mouse (Mus musculus).

An organic molecule or ion (usually a metal ion) that is required by an enzyme for its activity. It may be attached either loosely (coenzyme) or tightly (prosthetic group).

Any metabolite produced by all living cells.

A low-molecular-weight, non-protein organic compound participating in enzymatic reactions as dissociable acceptor or donor of chemical groups or electrons.

Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).

Any fungal metabolite produced during a metabolic reaction in Baker's yeast (Saccharomyces cerevisiae ).

Any bacterial metabolite produced during a metabolic reaction in Escherichia coli.

Any vitamin that dissolves in water and readily absorbed into tissues for immediate use. Unlike the fat-soluble vitamins, they are not stored in the body and need to be replenished regularly in the diet and will rarely accumulate to toxic levels since they are quickly excreted from the body via urine.

A product in capsule, tablet or liquid form that provide essential nutrients, such as a vitamin, an essential mineral, a protein, an herb, or similar nutritional substance.
