Properties of the alpha-helix. 1  The structure repeats itself every 5.4 Angstroms along the helix axis, ie we say that the alpha-helix has a pitch of 5.4 Angstroms. Alpha-helices have 3.6 amino acid residues per turn, ie a helix 36 amino acids long would form 10 turns.
Helix's Micro Precision Linear Actuators are also modular which allows them to be built into X, Y, Z motion systems and gantries. Helix has also loaded all of these new linear actuators into its 2D/3D CAD configuration allowing engineers to build an infinite amount of configurations.
