Vitamins, Minerals, and Nucleic Acids
Definition
Vitamins, minerals and nucleic acids are chemically different substances that all play essential roles in maintaining life, metabolism and cellular function.
Formula / Key Relation
Vitamins:
organic micronutrients.
Minerals:
inorganic micronutrients.
Nucleic acids:
large nucleotide-based biomolecules.
Examples of important roles:
Vitamin D → bone-related calcium regulation.
Iron → haemoglobin.
DNA → genetic information.
RNA → protein synthesis and gene expression.
Vitamins:
`small organic micronutrients`
Minerals:
`inorganic nutrients`
Nucleic acids:
`nucleotide polymers`
Vitamins, Minerals, and Nucleic Acids — Advanced
These categories illustrate the chemical diversity of life.
Small organic molecules such as vitamins can act in regulatory biochemical roles.
Inorganic ions such as Fe, Ca²⁺ and I-containing nutrients support structure or metabolism.
Large nucleotide polymers preserve and express biological information.

Vitamins, minerals and nucleic acids differ chemically but all perform essential biological functions.
Vitamins, minerals and nucleic acids represent three very different but essential biological chemical categories. Vitamins are organic micronutrients used in many regulatory processes. Minerals are inorganic nutrients such as calcium, iron and iodine. Nucleic acids are large polymers of nucleotides; DNA stores genetic information while RNA helps cells use it. Understanding their differences helps connect nutrition with cellular biochemistry.
