2.A helical conformation of a polypeptide chain, usually right-handed, with maximal intrachain hydrogen bonding; one of the most common secondary structures in proteins.
3.Crenshaw deciphered the algorithm of the twisting motion, known as helical klinotaxis, and assisted Nekton's team in applying it to the robots, in essence crafting a new guidance technology.
9.This invention, crafted meticulously with a coiling helical surface around a cylindrical shaft, transformed irrigation, a boon to the agrarian societies of the time, and even today.
10.At the end of a minute a dull splashing reverberated from the bottom of the well; the helical twist he had imparted to the rope had reached the grapnel below.
11.Add to that the fact that some baby beavers were found in the tunnels, and suddenly the idea that beavers had made these big helical burrows didn't seem so far-fetched.
12.Collagen and other structural proteins such as keratin, the protein our hair is made of, resist decay due to their linear helical structure, as well as various amino acids, the building blocks of protein that form them.
13.We had the software to be able to do type 1 hair, type 2 hair very easily, but we hadn't really figured out how to do coils that are actually helical and that actually look like springs.
