The development of prostate cancer within the contemporary society is seen as the most common form of virulent disease state affecting the male population especially within America (Yu et al. 2790). The progression of the cancer to an aggressive form is yet to be determined especially regarding what specific molecular mechanisms cause the cancer to turn severe (Yu et al. 2790). Prostate cancer grows through different stages such as the perinvasive period‚ the invasive stage and lastly androgen-independent

CHEM3412 Synthesis of a Porphyrin Porphyrins are hetereonuclear‚ macrocyclic compounds that play an important role in living organisms. Examples include the non-protein heme portion of hemoglobin in animals whereby the lone pairs on nitrogen can bind to the oxygen-carrying iron. In plants‚ chlorophyll uses the vast conjugation to allow absorption of light for photosynthesis. The characteristic colors of porphyrins is also due to the conjugation. An examination of the porphyrin structure

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic
