Abstract

Tryptophan is present in the serum in two forms: free (FT) and linked to the proteins, total tryptophan (TT) comprises both fractions. The fraction FT which is detached continuously from the proteinic link is able to pass the hemato-encephalic barrier and is utilized as a precursor for the formation of cerebral serotonin (McMenamy et al., 1957; Knott and Curzon, 1972).
