The amino acid composition of the developing larval cuticle and puparium of Calliphora vomitoria has been examined by means of paper chromatography. The most significant changes during development concern the aromatic amino acids. Phenylalanine and para-tyrosine apparently combine with the tanning quinone when the puparium hardens, and ortho-tyrosine is present for a brief period at about 7 days The presence of o-tyrosine, together with evidence resulting from the extraction of larval cuticles…

ELECTROPHORETIC STUDIES ON THE SHELL PROTEINS OF THE PRAWNS METAPENAEUS AFFINIS (M. EDW.) AND PENAEUS INDICUS (M. EDW.)
TLDR
Electrophoretic analysis of the proteins extracted from the shells of the two prawns disclose that each protein can be resolved into three fractions of different mobilities in the electrical field, all moving towards the anode.
Puparium Formation in Diptera
TLDR
Attention is directed to additional visual evidence indicating that hardening, darkening, and contraction are all separate processes.
La gestion des acides aminés aromatiques chez les Lépidoptères
TLDR
Although the chemistry of melanin formation is important in understanding certain physiological phenomena that affect both larval and adult Lepidoptera, it has never been studied in detail because of its complexity.

TLDR
It was found that during the metimorphosis of Calliphora the enzymatic amino acid oxidation has a maximum activity at the beginning and at the end of the pupil period but is at its minimum in the middle of this period in accordance with the total metabolism.
