Pyridoxal
Pyridoxal is a pyridinecarbaldehyde that is pyridine-4-carbaldehyde bearing methyl, hydroxy and hydroxymethyl substituents at positions 2, 3 and 5 respectively. Pyridoxal, also known as pyridoxaldehyde, belongs to the class of organic compounds known as pyridoxals and derivatives. Pyridoxals and derivatives are compounds containing a pyridoxal moiety, which consists of a pyridine ring substituted at positions 2, 3, 4, and 5 by a methyl group, a hydroxyl group, a carbaldehyde group, and a hydroxymethyl group, respectively. Pyridoxal is one form of vitamin B6. Pyridoxal exists in all living species, ranging from bacteria to humans. In humans, pyridoxal is involved in glycine and serine metabolism. Pyridoxal has been detected, but not quantified in several different foods, such as sourdoughs, lichee, arctic blackberries, watercress, and cottonseeds. Some medically relevant bacteria, such as those in the genera Granulicatella and Abiotrophia, require pyridoxal for growth. This nutritional requirement can lead to the culture phenomenon of satellite growth. In in vitro culture, these pyridoxal-dependent bacteria may only grow in areas surrounding colonies of bacteria from other genera ("satellitism") that are capable of producing pyridoxal. Pridoxal has a role as a cofactor, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite.

Taurocyamine
Taurocyamine is a guanidino-taurine analogue derived from taurine. It is an intermediate of taurine and hypotaurine metabolism. The concentration of taurocyamine present in the human urine and serum could be as low as 8-78 pmol/ml. (PMID: 6520173) Plasma levels of taurocyamine are significantly increased in patients with chronic renal failure with or without hemodialysis. (PMID: 10516995). Taurocyamine is an endogenous alkaline "shifter". It effectively reduces the extent of brain intracellular lactic acidosis brought about by anoxic insult. A pH alkaline shift may protect the brain against the deleterious effects of lactic acidosis. (PMID: 8241459). Taurocyamine is an inhibitor of taurine transport and a glycine receptor antagonist in the brain (PMID: 12411417). [HMDB] Taurocyamine is a guanidino-taurine analogue derived from taurine.
