WebWith our keratin products, your hair can be as straight and free of static as you want it to be. How Keratin Works. Keratin is made up of many amino acid chains. These chains are a major part of your hair, providing much of the framework for your hair. Once these proteins are damaged, your hair is damaged: the strands become weak, impaired and ... WebThe amino acids in an α helix are arranged in a helical structure, about 5 Å wide. Each amino acid results in a 100° turn in the helix, and corresponds to a translation of 1.5Å along the helical axis. The helix is tightly packed; there is almost no free space within the helix. All amino acid side-chains are arranged at the outside of the helix.
