Descriptor sustancias macromoleculares
Scope note: Compuestos y complejos moleculares con un gran número de átomos y suelen tener un tamaño superior a 500 kDa. En los sistemas biológicos, las sustancias macromoleculares se pueden visualizar generalmente usando el MICROSCOPIO ELECTRÓNICO y se distinguen de los ORGANELOS por la carencia de estructura membranosa.

Scope note: Compounds and molecular complexes that consist of very large numbers of atoms and are generally over 500 kDa in size. In biological systems macromolecular substances usually can be visualized using ELECTRON MICROSCOPY and are distinguished from ORGANELLES by the lack of a membrane structure.
