Knowra Theobromine Theobromine Theobromine is a bitter methylxanthine alkaloid found especially in cacao. It stimulates the central nervous system and has mild diuretic effects, but acts more slowly and less strongly than caffeine.
Methylxanthine : A class of alkaloids built on a xanthine structure with one or more methyl groups. Theobromine belongs to this chemical family, which also includes caffeine.
Theobroma cacao : A tropical evergreen tree whose seeds are processed into cocoa and chocolate. Its seeds are the main natural source of theobromine.
Chocolate toxicity in dogs : Poisoning in dogs caused by methylxanthines in chocolate, especially theobromine and caffeine. Dogs clear theobromine slowly, so chocolate can cause dangerous accumulation.
Caffeine : A methylxanthine alkaloid that stimulates the central nervous system and occurs in coffee, tea, and other plants. Theobromine is less potent as a central stimulant and has a longer-lasting, milder profile.
Adenosine receptor antagonist : A substance that blocks adenosine receptors, reducing the effects of adenosine signaling. Theobromine can antagonize these receptors, contributing to its stimulant effects.
Cacao bean : The seed of Theobroma cacao, fermented and processed to make cocoa products. Theobromine accumulates in these seeds and contributes to their bitterness.
Methylxanthine poisoning : Toxic effects caused by excessive exposure to methylxanthine compounds. Theobromine overdose produces a form of methylxanthine poisoning.
Theophylline : A methylxanthine drug used chiefly to treat airway narrowing in respiratory diseases. Theophylline has stronger bronchodilator effects and a different clinical role.
Phosphodiesterase inhibitor : A substance that reduces the activity of enzymes that break down cyclic nucleotides. Theobromine inhibits phosphodiesterases at sufficiently high concentrations, affecting cellular signaling.
Cocoa powder : A powder made from cacao solids after much of the cocoa butter has been removed. Removing fat concentrates cacao solids, making cocoa powder a substantial dietary source.
