&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Precursor&amp;#039;&amp;#039;&amp;#039; refers to a substance from which another, usually more complex or mature substance, is formed. In [[biology]], precursors are substances that are converted into another substance (a [[metabolite]]) in a [[chemical reaction]]. In [[biochemistry]], the term &amp;quot;precursor&amp;quot; is used more specifically to refer to a chemical compound preceding another in a metabolic pathway, such as a protein precursor.&lt;br /&gt;
&lt;br /&gt;
== Biology ==&lt;br /&gt;
In biology, a precursor is a substance from which another is formed, especially by metabolic reaction. This can refer to chemical compounds that become another compound through a chemical reaction, or to cells that have not yet reached their final mature state. For example, a [[stem cell]] can be considered a precursor to the mature cells it will eventually become.&lt;br /&gt;
&lt;br /&gt;
== Biochemistry ==&lt;br /&gt;
In biochemistry, a precursor is a substance that is converted into another substance in the body. This can refer to substances that are used in the synthesis of compounds in the body, such as [[amino acids]] being the precursors to [[proteins]]. Precursors can also refer to substances that are converted into active forms in the body, such as the conversion of [[vitamin D]] into its active form in the body.&lt;br /&gt;
&lt;br /&gt;
== Medicine ==&lt;br /&gt;
In medicine, a precursor often refers to a substance or cell from which another, usually more active or mature substance or cell is formed. For example, in [[oncology]], a precursor lesion is an abnormal growth that is likely to become cancerous if not treated. Similarly, in [[hematology]], a precursor cell is a blood cell in an early stage of differentiation.&lt;br /&gt;
