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).
Lactic acid is an organic compound with the formula CH3CH(OH)CO2H. In its solid state, it is white and water-soluble. In its liquid state, it is clear. It is produced both naturally and synthetically. With a hydroxyl group adjacent to the carboxyl group, lactic acid is classified as an alpha-hydroxy acid (AHA). In the form of its conjugate base called lactate, it plays a role in several biochemical processes. In solution, it can ionize a proton from the carboxyl group, producing the lactate ion CH. 3CH(OH)COâ. 2. Compared to acetic acid, its pKa is 1 unit less, meaning lactic acid deprotonates ten times more easily than acetic acid does.
