Incorporation Of Phosphoproteins And Phenol-Bound Proteins Into The Cuticle Of Periplaneta Americana, Joseph Atchison Florence Iv

Theses and Dissertations

The incorporation of phosphoproteins and phenol-bound proteins into the cuticle of Periplaneta americana was analyzed. Radioactive monosodium phosphate was injected into newly ecdysed cockroaches. Incorporation into haemolymph proteins as well as tanned cuticle was observed. Phosphoproteins were observed to be combined with the cuticle to a greater extent than monosodium phosphate. This suggests that phosphate is being incorporated into the cuticle more readily than monosodium phosphate. The relevance of these observations is discussed in light of phosphate being a possible crosslinking agent between chitin and cuticle protein.

Binding of dopamine metabolites to cuticle proteins was investigated. Specific metabolites studied were …
