| porphyrins | A group of compounds containing the porphin structure, four pyrrole rings connected by methine bridges in a cyclic configuration to which a variety of side chains are attached. The nature of the side chain is indicated by a prefix, as uroporphyrin, haematoporphyrin, etc. The porphyrins, in combination with iron, form the haem component in biologically significant compounds such as haemoglobin and myoglobin.

| porphyromonas | A genus of gram-negative, anaerobic, nonsporeforming, nonmotile rods or coccobacilli. Organisms in this genus had originally been classified as members of the bacteroides genus but overwhelming biochemical and chemical findings indicated the need to separate them from other bacteroides species, and hence, this new genus was created. (12 Dec 1998) |

See Purple. <geology> A term used somewhat loosely to designate a rock consisting of a fine-grained base (usually feldspathic) through which crystals, as of feldspar or quartz, are disseminated. There are red, purple, and green varieties, which are highly esteemed as marbles. <zoology> Porphyry shell, a handsome marine gastropod shell (Oliva porphyria), having a dark red or brown polished surface, marked with light spots, like porphyry.

| Porifera |
The sponges or poriferans (from Latin porus "pore" and ferre "to bear") are animals of the phylum Porifera. They are primative, sessile, mostly marine, waterdwelling filter feeders that pump water through their matrix to filter out particulates of food matter. Sponges are among the simplest of animals, with partially differentiated tissues but without muscles, nerves, and internal organs. In some ways they are closer to being a cell colony than multicellular organisms. ...

| Porter |
Porter is a lunar impact crater that is located in the southern part of the Moon, and lies across the northwestern rim of the huge Clavius walled-plain. Although generally circular, the form of this crater has been modified by the geometry of the surface on which it was formed. The outer rim is generally lower to the southwest, where it lies on the floor of Clavius. Likewise the interior floor is flatter near this face. ...
