Nonphosphorylated is a term commonly used in biochemistry to describe molecules or compounds that do not contain a phosphoryl group. Synonyms for nonphosphorylated include dephosphorylated, unphosphorylated, and demethylated. These terms refer to the removal of phosphate groups from a molecule or compound, resulting in a nonphosphorylated form. Other related terms may include non-phosphorylable, nonphosphorylatable, and non-phosphorylated state. The use of these synonyms is important in research and experimentation where the presence or absence of a phosphoryl group can significantly affect the function or properties of a molecule or compound.
