Taurine Source

Taurine

Taurine is a semi-essential amino acid (conditionally essential) that is known as a sulfur containing beta-amino acid due to its structure. It comprises over 50% of the free amino acid pool of cardiac tissue (highly prominent) but is located systemically in lower concentrations, particularily the testicles where it is the most prominent free amino acid. In general, taurine is present in excitable tissues more than others although as its transporter is expressed ubiquitously it could be assumed taurine is omnipresent in the human body.
Unlike other amino acids and more like beta-amino acids, taurine is not a structural component of any quaternary proteins or peptide bonds and resembles a peptide neurotransmitter (like adrenaline or dopamine) more than classical dietary proteins.
