Anthranilic acid (vitamin L)

----------------------------------------------------------------------

----------

Anthranilic acid (vitamin L) is an intermediate in the biosynthesis

of tryptophan. Vitamin L1 is anthranilic acid or ortho-aminobenzoic

acid, a vitamin required for lactation in human females. Vitamin L2

is adenyl thiomethylpentose, an alternate form of vitamin L. Vitamin

L is thought to be necessary for lactation -- the reason for the " L " -

- although it is not officially recognized as a vitamin and dietary

sources have not been identified. L2 was isolated and seems to be

related to adenosine. It has been referred to as LT but LT is a much

more complex substance and is sometimes erroneously included with the

B vitamin complex. Anthranilic acid is an aromatic amine which occurs

physiologically as a metabolite of the amino acid tryptophan. It is

used commercially as an intermediate in dye synthesis.

How would one access it?
