Please explain tetrapyrrole's structure???
Tetrapyrrole is a structure found in heme moiety and other porphyrins , chlorophyll etc. In this structure four pyrrole rings are attached together via direct covalent bond at alpha position carbon atoms or one carbon ridge like(=CH or >CH2 ).
The structure is given as:
Tetrapyrrolesare a class ofchemical compoundscontaining fourpyrrolerings held together by directcovalent bondsor by one-carbon bridges (=(CH)-or-CH2-units), in either a linear or a cyclic fashion.
Some tetrapyrroles are the active cores of some compounds with crucialbiochemicalroles in living systems, such ashemoglobinandchlorophyll).
