Identify the functional groups present in ibuprofen. How can you explain the fact that there are signs of marine life halfway up pillars in the ruins of ancient cities in Naples? [8] Like other NSAIDs, it works by inhibiting the production of prostaglandins by decreasing the activity of the enzyme cyclooxygenase (COX). To an organic chemist, ibuprofen is a white powder known also as (+/-)-2-(p-isobutylphenyl) propionic acid and has a molecular weight of 206.29, a melting point of about 76 degrees Celsius, and two isomers (R and S). B) They are found in amino acids. The low dissociation constant indicates that ibuprofen molecules in a solution remain in undissociated form. The functional groups of anything are the croups that aren't normal alkane (single carbon-hydrogen bonds) groups. attached to the opposite side. E) They exhibit considerable molecular complexity and diversity. In the presence of enzymes, prostaglandin H2H_{2}H2 is converted to prostaglandins, which relieve one from pain, fever, and inflammation, and to thromboxane A2A_{2}A2 which helps in clotting blood.
