Definition of helicity in English:

helicity

noun hiːˈlɪsɪtihəˈlisədē

mass noun

1Biochemistry
Helical character, especially of DNA.
DNA〔主生化〕（尤指DNA的）螺旋度，螺旋结构
Example sentencesExamples
- In addition, its helicity could be further increased.
- Mechanistically, the expansion event begins with a slight loss of helicity in the stem region.
- The reason for the relatively low helicity of long peptides is unclear to us.
- One peptide was designed to maximize helicity and the other, having the same composition but a different sequence, was designed to minimize helical formation.
- This reduced its helicity and increased its average tilt, thereby presumably reducing fusion efficiency.
2Physics
A combination of the spin and the linear motion of a subatomic particle.
〔物理〕螺旋性
Example sentencesExamples
- One physicist later wrote that, had Maurice Goldhaber not existed, ‘I am not sure that the helicity of the neutrino would ever have been measured‘.
- Linear equations can't easily capture magnetic field helicity, a property that prevents much of the field's energy from dissipating as heat.

Origin

1950s (in sense 2): from Latin helix, helic- 'spiral' + -ity.
