Unformatted text preview: right on top of each other 3) (based off Lehn. 4-3) Hair grows at a rate of 0.3 mm/day. All this growth is concentrated at the base of the hair fiber, where -keratin filaments are synthesized inside living epidermal cells and assembled into ropelike structures. The fundamental structural element of -keratin is the -helix. Using what you know about the dimensions of an -helix, about how many amino acids would be added to a hair in one day, and what would the estimated MW be for these added amino acids? You only need to set up this problem. 0.3x10-3 m 1 1 turn 3.6 aa Day 10-10 m 5.4 1 turn Glutamate Histidine A B C D A B C D +1 0 -1 -2 A B D C A B C D = # of aa x 110 = MW...
