✦ Synopsis

Since many of the marine invertebrates are free from myoglobin and hemoglobin pigments which would interfere with direct spectral measurements of intact cytochromes, they offer great advantages in studying distribution of cytochromes. The cytochromes of some marine invertebrates correspond spectrally to the well known cytochromes a + a3, b, c and c1 of mammalian mitochondria. Spectral evidence for other cytochromes of the a and b types has been found (Tappel, '60). In our previous study of the cytochromes of muscles of blue crab, American lobster, shrimp, eastern oyster, northern quahog clam, and bay and sea scallops, room temperature difference spectra were used for qualitative and quantitative measurements. More exact qualitative identification was made by spectra taken at liquid nitrogen temperatures. This previous study establishes background for further survey of marine invertebrates because it shows the applicability of direct difference spectra for qualitative assignments of cytochromes and for quantitative measurements.

This paper reports spectral measurements of the cytochromes of a wide variety of invertebrates in the phyla Mollusca and Arthropoda.
