Inorganic ions such as calcium, iron and magnesium needed for bones, blood, nerves and enzymes.
Calcium builds bones and triggers muscle contraction and clotting; iron is in haemoglobin and cytochromes; magnesium sits in chlorophyll and activates ATP; sodium and potassium set membrane potentials; iodine is needed for thyroid hormones; zinc is a cofactor in many enzymes.
Both deficiency and excess can be harmful.

Minerals in Biology is one of the 51 topics in Biomolecules & Biochemistry. It is rated Beginner, so it suits learners who are starting out in biology. Related topics in this area include Vitamins, Proteins, Tertiary Structure.
Iron deficiency causes anaemia, with fatigue due to reduced oxygen transport.
Minerals in Biology is a Beginner topic, so no earlier topic is required. Other Beginner topics in Biomolecules & Biochemistry that pair well with it include Water Properties, Carbon Chemistry, Carbohydrates.
The closest topics to Minerals in Biology are Vitamins, Proteins, Tertiary Structure, Cofactors and Coenzymes. Comparing them side by side is a good way to see how the ideas connect.
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Minerals in Biology. To practise the whole of Biomolecules & Biochemistry, use the Biomolecules & Biochemistry quiz.
Minerals in Biology: Inorganic ions such as calcium, iron and magnesium needed for bones, blood, nerves and enzymes. Vitamins: Organic micronutrients needed in small amounts, often serving as coenzymes in metabolic reactions. Read both side by side and note what each one explains.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Vitamins and explain the difference aloud. Finally, take the Biomolecules & Biochemistry quiz and come back to this page for any question you miss.
