STUDIES OF PROTOPORPHYRIN

Studies on the biosynthesis of heme from iron and protoporphyrin.

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Studies of Protoporphyrin: Iv. a Comparison of the Erythrocyte Protoporphyrin Concentration with the Reticulocyte Percentage under Experimental and Clinical Conditions.

Time-resolved fluorescence studies on protoporphyrin IX-apohorseradish peroxidase.

The hemin moiety of horseradish peroxidase (donor:hydrogen-peroxide oxidoreductase, EC 1.11.1.7) was removed and the apoprotein reconstituted with the fluorescent protoporphyrin IX. Steady-state and time-resolved fluorescence properties of the HRP(desFe) adduct were examined; the multifrequency phase and modulation method was utilized for lifetime and dynamic polarization studies. The emission ...

Acid denaturation studies on a cobalt(3) protoporphyrin-globin complex.

A cobalt (III)-protoporphyrin IX complex of horse globin (cobaltiglobin) has been prepared and its stability toward acid denaturation determined. Unlike iron(II1) protoporphyrin, which combines with. globin to give ferrihemoglobin, cobalt(II1) protoporphyrin combines with globin to give a complex which experimentally resembles an internal ferrihemichrome in which the heme is attached to the pro...
