Abstract
IN silkworms, it has been found that tyrosine is used not only for biosynthesis of the silk proteins1, but also to form melanin pigments, but little is known of its origin. The present work was carried out, using phenylalanine labelled with carbon-14, to examine whether phenylalanine is a precursor of tyrosine.
