| The breakdown of porphyrin yields bilirubin, a product that is non-polar and therefore, insoluble. |
| To non-polar people no words can convey an adequate idea of the dangers to be met, of the privations to be endured. |
| Typically, hydrocarbon resins are non-polar, and thus highly compatible with non-polar rubbers and polymer. |
| The oil phase is composed of non-polar materials that are not soluble in water. |
| The non-polar groups prefer to interact with each other, and exclude water from these regions, leading to immiscibility. |
| You may need to redissolve in hot water, basify to 9 or 10, add a non-polar solvent, and extract the solvent layer weekly for 3 weeks. |
