I have removed the following text from the article (currently in a hidden comment):
According to IUPAC recommendations the term macromolecule is reserved for an individual molecule, and the term polymer is used as to denote a substance composed of macromolecules. Polymer may also be employed unambiguously as an adjective, according to accepted usage, e.g. polymer blend, polymer molecule.
The reasons are as follows:
- The sentences are lifted verbatim from a 1996 IUPAC report. The citation is not noted in quotations and may constitute plagiarism. Original Source
- The IUPAC recommendation appears to be an attempt to disambiguate the usage of the term polymeramong polymer scientists. The full report (here) suggests that the terms macromolecules and polymer molecule are indistinguishable. This may be true for the narrow purview of polymer science but ignores the well-established practice of describing large biologicall molecules (such as proteins, which are rarely described as polymers) or lipids (definitely not polymers) as macromolecules.
That being said, the referenced IUPAC report has some valuable information which should be added in future revisions to the article. Irene Ringworm 18:59, 23 February 2007 (UTC)

The DNA,_RNA_and_proteins:_The_three_essential_macromolecules_of_life page is an in depth discussion of DNA, RNA and protein and the main Macromolecule page is pretty short.
- Merge - I think they could sensibly be combined if the synthetic macromolecule section was also expanded to balance the influx of biological information. The DNA, RNA, protein page has far fewer visits but currently the more useful information. T.Shafee(Evo﹠Evo)talk 00:55, 25 April 2015 (UTC)
I've gone ahead and merged the articles, since I think that the information is useful here and macromolecule gets 4 times the traffic. I've also edited the prose to fit encyclopaedic style a little more. T.Shafee(Evo﹠Evo)talk 06:15, 28 June 2015 (UTC)

The purpose of this article is to provide a single location whereby people who are confused about molecular biology can come to understand the functional and chemical differences between DNA, RNA and proteins. John Mackenzie Burke (talk) 12:51, 3 June 2011 (UTC)

I found the article to be heavily focused on linear polymers, such as DNA and RNA. In fact, a bulk of the article revolves around the central dogma and how DNA encodes the for RNA, which will ultimately encode proteins. Also, there is a clear bias, in that the author uses words like "far better" when phrases such as "more efficient" can be used to separate the functional consequences of the structures of both DNA and RNA. The section on branched polymers is quite sparse, and ideally, should include the specific alpha and beta linkages that are seen amongst glucose polymers to form glycogen, cellulose, and etc. Yes, there are links to those aforementioned articles, however, a brief discussion may be useful. As mentioned earlier, there is a clear preference for biological macromolecules and very little material devoted to synthetic macromoleculesPolymer33 (talk) 18:01, 6 April 2017 (UTC)
