Function and Regulation of Taurine in the Pineal Gland
Taurine is highly concentrated in the pineal gland, where it occurs at 20–60 mM (Crabai et al., 1974; Green et al., 1962; Guidotti et al., 1972; La Bella et al., 1968; Vellan et al., 1970). This is higher than the concentration of taurine in any other body tissue, except the neurohypohysis. It is also relatively abundant compared to other amino acids in the pineal gland, comprising 30% of the free amino acids of the adult gland (Nir et al., 1974). In view of these observations, it is surprising that little is known about the role of taurine in this tissue.
