These are energetic and structural substances found in many foods that we eat daily. There are two groups:

Simple Carbohydrates

  • Monosaccharides: They are the simplest ones.
  • Disaccharides: They are formed by two monosaccharides joined together.

Complex Carbohydrates (Polysaccharides)

They are neither sweet nor crystalline and they are not soluble in water. They include:

  • Starch: It is made up of glucose molecules.
  • Cellulose: It makes up vegetal fibre and forms the plant cellular wall. It is also made up of glucose molecules.

Inorganic Substances

These are small inorganic substances with variable composition. In solid state, they are structural. In dissolution, they are regulatory and allow our organs to function correctly and intervene in the regulation.
