Spanish from Spain

Descriptor	estructura proteica alfa-helicoidal
Entry term(s)	conformación alfa-espiral de proteína estructura alfa-helicoidal de la proteína estructura alfa-helicoidal de proteínas estructura alfahelicoidal de la proteína estructura alfahelicoidal de proteínas estructuras alfa-helicoidales hélice alfa hélices alfa
Scope note:	Estructura secundaria de proteínas formada por una hélice o espiral hacia la derecha donde cada grupo amino (N-H) de la cadena principal del péptido contribuye a formar un enlace de hidrógeno con el grupo carbono (C=O) de los cuatro residuos N-terminales del aminoácido (n-4). Es la clase más frecuente de estructura secundaria.

Scope note:

A secondary structure of proteins that is a right-handed helix or coil, where each amino (N-H) group of the peptide backbone contributes a hydrogen bond to the carbonyl(C=O) group of the amino acid four residues N-terminal to it (n-4). It is the most common type of secondary structure.
