What feature distinguishes minerals from vitamins?

Minerals are characterized as inorganic substances, meaning they do not contain carbon and are typically derived from the earth or water. This classification is fundamental since it distinguishes them from vitamins, which are organic compounds and contain carbon. The inorganic nature of minerals allows them to play crucial roles in various physiological processes, including bone formation, fluid balance, and nerve transmission. For example, minerals such as calcium, potassium, and iron are essential for maintaining health and must be obtained from dietary sources. Understanding this distinction is vital for recognizing the different roles that minerals and vitamins play in nutrition and overall health.
