The phrase "a subgroup of molecules" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing a specific category or classification of molecules within a larger group.
Example: "In our study, we focused on a subgroup of molecules that exhibit unique properties under certain conditions."
Alternatives: "a subset of molecules" or "a category of molecules".
Taken together our study demonstrates potential far-reaching effects of the application of CAMPs on the eukaryotic host cell and provides insight into the consequences of peptide binding on the plasma membrane localization and endocytosis of a subgroup of membrane molecules.
We applied this technique to analyze the effects of three members of the contactin family (Cntn4, -5, -6), a subgroup of cell-adhesion molecules that play essential roles in the development of neuronal circuits.
Control over the expression of one or a subgroup of genes with targeted small molecules is a major goal of chemical biologists.
When the whole sample is considered, the H5a subgroup of molecules, harboring the 4336 transition in the tRNAGln gene, already associated to AD in early studies, was about threefold more represented in AD patients than in controls (2.0% vs 0.8%; p = 0.031), and it might account for the increased frequency of H5 in AD patients (4.2% vs 2.3%).

Our results may lead to the rational design of anticancer molecules targeting a subgroup of gastric cancer cells overexpressing both HER2 and topoisomerase IIα.
The carcino embryonic antigen-related cell adhesion molecules (CEACAMs), a subgroup of the CEA family of immunoglobulin-related proteins, are encoded in the human genome by 12 genes [ 1, 2].
Prospective evaluation of a subgroup of these patients indicates that combined anti-inflammatory/immunosuppressive treatment further downregulated expression of these molecules.
With recognition of these factors, it is evident that strictly invariant features of the sequence of a subgroup of nitrogenases play an important role in the structure and/or function of the protein molecule itself.
