Examples of papers which are not appropriate for International Journal of Biological Macromolecules include:
papers where the biological macromolecule has not been characterized by modern analytical techniques (including molecular weight) rather than historical methods. e.g. colorimetric assays.
papers which focus on biological, physiological and pharmacological aspects of non-macromolecules attached to, or mixed with, biological macromolecules.
papers on the materials science of biocomposites where there is no mention of any specific biological macromolecule.
papers where the structure or role of the biological macromolecule is not the major proportion of the study.
routine studies of extraction of macromolecules without purification and characterization of the extracted molecule.
applications of macromolecules where the structure of the macromolecule is completely unknown.
Papers where the molecular weight of the biological molecule is less than five thousand.
Paper which are majorly about clinical studies and animal trials, where a biological macromolecule is not the biologically active agent, and/or the biological macromolecule is not the major focus of the study.
