The phrase "a system of molecules" is correct and usable in written English.
It can be used in scientific contexts, particularly in chemistry or biology, to describe a collection or arrangement of molecules that interact or function together.
Example: "In this experiment, we will analyze a system of molecules to understand their behavior under different temperatures."
Alternatives: "a network of molecules" or "a collection of molecules".
This is done by comparing a set of cell-surface proteins called human leukocyte antigen (HLA)—a system of molecules that enable components of the immune system such as T cells to mount an attack against foreign substances.
Consider a system of molecules of mass m traveling with a velocity v in an enclosed container.
Most organisms, including flies and people, have central clocks located in the brain that keep time with a system of molecules that build up and degrade throughout the day.
Molecular dynamics (MD) simulation, the computational method that simulates detailed material behavior by simultaneously solving the equations of motion for a system of molecules interacting with given potentials has been applied in various disciplines.
Our approach to bond energies and thermochemistry is to emphasize that energy is stored in a system of molecules (rather than in a particular molecule).
More generally, how a system of molecules can function together to target dynein to the plus end is not clear in any system.
Now, researchers in Germany have come up with a system of molecule-size sensors that can measure cellular reactions in vivo.
General Lagrange's equations of motion for a system of polymeric molecules are obtained in an explicit form.
A system of regulatory molecules interacts at the cellular level to control and coordinate the many metabolic pathways that constitute normal mineral metabolism.
His aim is to prove that whatever the initial state in such a system of gas molecules, it must inevitably approach the state characterized by the Maxwell distribution (WA I, 320).
We incorporate dynamic replication and decay rates into the standard quasispecies theory of molecular evolution, and show that for periodic time-dependencies, a system of evolving molecules enters a limit cycle for t→∞.
