Far-infrared studies on hemin and hemin-like complexes

Biochimica et Biophysica Acta (BBA) - General Subjects, 1971
Abstract Far-infrared absorption spectra in the submillimeter region were observed at about 2°K on some halogen complexes of protoporphyrin (Fe3+) and tetraphenylporphyrin (Fe3+) using in Michelson interferometer. The D values in the spin Hamiltonian H = D [S Z 2 − 1 3 S(S+1)] which describes the ground sextet of the 3d ...

A novel Fe-hemin-metal organic frameworks supported on chitosan-reduced graphene oxide for real-time monitoring of H2O2 released from living cells.

Analytica Chimica Acta, 2020
Herein, a kind of novel hemin-based metal organic frameworks (Fe-hemin-MOFs) with unique peroxidase-like bioactivity was developed for the first time. The synthesized Fe-hemin-MOFs exhibited satisfactory catalytic activity toward hydrogen peroxide (H2O2).

Of Hemin Bondage

Science's STKE, 2003
Tang et al. used structural and electrophysiological analysis to uncover a novel role for heme (the iron-containing cofactor that forms a prosthetic group essential for oxygen transport in heme-containing proteins) as an inhibitor of K + flux through Slo1 BK ion channels.

Sandwich-type electrochemical immunosensor for sensitive detection of CEA based on the enhanced effects of Ag NPs@CS spaced Hemin/rGO.

Biosensors & bioelectronics, 2019
An ultrasensitive sandwich-type electrochemical immunosensor was designed by using gold nanoparticles (Au NPs) as the substrate material and microporous carbon spheres (CS) loading silver nanoparticles (Ag NPs) spaced Hemin/reduced graphene oxide (Hemin ...

Identification of frozen/thawed beef based on label-free detection of hemin (Iron Porphyrin) with solution-gated graphene transistor sensors

, 2020
The fraud labeling of frozen/thawed meat as fresh meat has become one of the severe problems in the current meat products market. Hemin, as a highly bioavailable iron form in beef, loses with exudates during freezing and thawing cycles.
