Coiling: in the shape of a coil
A helix (pl: helixes or helices) is a type of space curve, i.e. a smooth curve in three-dimensional space. It is characterised by the fact that the tangent line at any point makes a constant angle with a fixed line called the axis. ...
The alpha helix (u03B1-helix) is a common secondary structure of proteins and is a righthand-coiled or spiral conformation (helix) in which every backbone N-H group donates a hydrogen bond to the backbone C=O group of the amino acid four residues earlier (n n n n in +n 4n u2192n in n n {displaystyle i+4rightarrow i}n n hydrogen bonding)...
(Helicals) A derivative of the word Helix for its shape, Helicals are spirals of wire used to secure adjacent coils in Innerspring Mattresses.
(Helices) 1988. Bsn, synthesizer. Ms
A small helix or spiral shaped wire that is used to connect coils.
Refers to the way fletching is laid on an arrow. Rather than straight, helical fletching curves slightly around the arrow shaft.
Wrapped in a spiral fashion. Refers to the way the strands of a conductor are laid.
