Get geeky with molecules! Porphyrins are a group of organic molecules with a central ring structure. Their crisp geometric shapes when translated into crochet create striking pendants for jewelry. This trio of porphyrins reveals the similarity between two commonly known and one not-so-well known molecules. Chlorophyll is the green pigment found in plants and is critical to photosynthesis. At its center you’ll find a Mg2+ atom. Heme is the red pigment in mammalian blood and transports gases. At its center you’ll find an Fe2+ atom. Phthalocyanine is a brilliant blue-green pigment used in dyeing. At its center you’ll find a Cu atom. Short slip stitch extensions represent additionally bonded atoms to the molecule.
