your hair is composedof protein known as keratins that have an alpha helix- like fibrous structure. the alpha helix-structure has approximately 3.6 amion acids per turn of of the helix and a linear dimension of 0.54nm per turn of the helix. for simplicity, let’s imagine that a strand of hair is composed of a single keratin molecule in this alpha helix-like state. if you were to grow 25mm(~1inch) in one year, how many turns of alpha helix must be aIDed to the keratin molecule each minute of the year?
