SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

International Journal of Biological Macromolecules is an established international journal of research into chemical and biological aspects of all natural macromolecules.It presents the latest findings of studies on the molecular structure and properties of proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins, biological poly-acids, and nucleic acids. These findings must be new and novel rather than a repeat of earlier or analogous published work. The scope includes biological activities and interactions, molecular associations, chemical and biological modifications, and functional properties. Papers on related model systems, structural conformational studies, theoretical developments and new analytical techniques are also welcome. All papers are required to focus primarily on at least one named biological macromolecule. This naming should appear in the title, the abstract and the text of the paper.
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.
