magnesium as a central metal atom, replacing the two NH centers in the parent.

Variation

Microbes produce two reduced variants of chlorin, bacteriochlorins and isobacteriochlorins. Bacteriochlorins are found in some bacteriochlorophylls; the ring structure is produced by Chlorophyllide a reductase (COR) reducing a chlorin ring at the C7-8 double bond. Isobacteriochlorins are found in nature mostly
