Four notable events take place on the mountain each year. The Pikes Peak Ascent and Marathon, a 26-mile round trip foot race up Barr Trail and then back down each August, draws thousands of runners from all over the world. The current Pikes Peak Marathon record, which was set in 1993, is 3 hours 16 minutes 30 seconds. The second event, the Pikes Peak International Hill Climb is a race on the 12.42-mile road, which starts around the 6 1/2 mile mark on the highway. In 2013, Sebastian Loeb set a new record of 8 minutes 13.878 seconds.
In mammals, arachidonic acid is synthesized from linoleic acid. Biochemistry. A polyunsaturated omega-6 fatty acid, which is an essential dietary component for mammals and the precursor for biosynthesis of prostaglandins, thromboxanes and hydroxy-eicosatetraenoic acid derivatives (e.g., leukotrienes). polyunsaturated omega-6 fatty acid, which is an essential dietary component for mammals and the precursor for biosynthesis of prostaglandins, thromboxanes and hydroxy-eicosatetraenoic acid derivatives (e.g., leukotrienes).
Acetic acid /ÉËsiËtÉ¨k/ , systematically named ethanoic acid /ËÉÎ¸ÉËnoÊÉ¨k/ , is an organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H or C 2 H 4 O 2).It is a colourless liquid that when undiluted is also called glacial acetic acid.lacial acetic acid is a name for water-free (anhydrous) acetic acid. Similar to the German name Eisessig (ice-vinegar), the name comes from the ice-like crystals that form slightly below room temperature at 16.6 Â°C (61.9 Â°F) (the presence of 0.1% water lowers its melting point by 0.2 Â°C).
