The phrase "a single functional group" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry, to refer to one specific group of atoms responsible for the characteristic reactions of a compound.
Example: "In organic chemistry, a molecule can be classified based on the presence of a single functional group, such as an alcohol or a carboxylic acid."
Alternatives: "one functional group" or "a solitary functional group".
Consequently, fungus-growing termites should not be regarded as a single functional group when considering their influence on grass communities.
BSC also appear to behave as a single functional group, which is helpful when proposing general management policies for soil ecosystems protection.
Considering the more complex structure of the Glu stabilizer, a sole effect of a single functional group is not possible.
While many plants have flowers specialized for a single functional group of pollinators, such as moths or bees, and sometimes even a single pollinator species, it is relatively rare for insect pollinators to specialize on flowers of a particular plant species.
Both approaches were focused on the preparation of a single functional group on the particle surface.
Gold nanospheres with a single functional group on their surface have been synthesized using a solid-phase place exchange reaction [19], [20], [21].
It is noted, however, that guanine is the bulkiest of the four nucleotides, since it is purine based and possesses two exocyclic functional groups (a primary amine and carbonyl) compared with the single functional group on the other purine nucleotide, adenine.
In this work, a novel alternative strategy to enhance membrane performance was suggested via the combination of multiple functional groups into membranes, by which not only could circumvent the limitations of single functional group used, but also could achieve the synergistic effects of different functional groups.
Compounds within each series probed single functional group changes that expanded toward and eventually breached the substrate envelope.
Thus, although single functional group removals from the vinblastine lower subunit typically result in pronounced and additive losses in activity, two unprecedented deep-seated structural changes to the core structure were found that maintain potent activity.
Model additives, especially synthesized for this study, included: polyethylene chains, which possess either a single functional end-group or multiple functional groups along the chain, as well as functional diblock copolymers.
