Medical Definition of Chlorin

1. 2,3-Dihydroporphin(e); 2,3-dihydroporphyrin;one of the root structures of the chlorophylls (for structure, see porphyrin). Addition of the two-carbon bridge (see structure of chlorophyll) to chlorin yields phorbin(e); addition of side chains yields the phorbides, distinguished by a number of arbitrary prefixes (those found in the chlorophylls are pheo-and bacteriopheophorbide); esterification of the propionic group by phytyl yields the respective phytins, and the addition of magnesium yields the chlorophylls (magnesium phytinates). See: porphyrins. (05 Mar 2000)
