Descriptor English:

Protein Structure, Secondary

Descriptor Spanish:

Estructura Secundaria de Proteína

Spanish from Spain

Descriptor	estructura secundaria de las proteínas
Scope note:	Nivel de la estructura proteica en el cual las interacciones regulares de los puentes de hidrógeno en tramos contiguos de la cadena polipeptídica dan lugar a HÉLICES ALFA, CADENAS BETA (que se alinean formando las LÁMINAS BETA) u otros tipos de espiral. Este es el primer nivel de plegamiento de la conformación proteica.

Descriptor Portuguese:

Tree number(s):

G02.111.570.820.709.600

RDF Unique Identifier:

https://id.nlm.nih.gov/mesh/D017433

Scope note:

The level of protein structure in which regular hydrogen-bond interactions within contiguous stretches of polypeptide chain give rise to ALPHA-HELICES; BETA-STRANDS (which align to form BETA-SHEETS), or other types of coils. This is the first folding level of protein conformation.
