dard N-protecting groups are not affected by the reaction conditions. Similar success is achieved witha poly-TPP and iodine reaction mixture.16 Fmoc, Cbz, and Boc groups were utilized as N-protectinggroups, and methyl, allyl, benzyl, and t-butyl esters were employed. Hindered amino acids (Fmo[r]

55) Why does sweating cool your skin on a hot, dry day but makes you feel warmer on a hot,humid day?Answer: Possible Answer: The evaporative cooling of sweat cools the skin as the water and theheat it has absorbed move from the skin to the drier air. Sweat does not evaporate as well on ahumid[r]
