Expert writing Tips
Best practice
When describing the function of a molecule, ensure you clearly define the context in which it is essential. For example, specify the biological process, cellular function, or chemical reaction where the molecule plays a critical role.
Common error
Avoid using "molecule essential for" when the molecule merely enhances a process rather than being absolutely required. Consider using weaker terms like "contributes to" or "involved in" if the molecule's role is not critical.
