Lesson: Chapter 1 — The Chemical Basis of Life

1.7. Vitamins 2 of 4

Water-soluble vitamins: B and C

There are two water-soluble vitamins: B and C. Because they are not stored in the body, they have to come from food regularly.

Vitamin B

What it is for

  • The proper condition of nerve tissue
  • A component needed for forming red blood cells
  • Keeping skin healthy
  • Fat metabolism
  • Forming bone marrow
  • Maturation of red cells and formation of antibodies

Deficiency symptoms

  • Beriberi
  • Sores at the corners of the mouth
  • Anaemia
  • Dry skin and changes in its colour

Extra knowledge — B is not one vitamin

Vitamin B is a complex vitamin. It has variants: B1, B2, B6, B12. These reach the body through food, and some of them are produced by bacteria living in the human intestine.

Vitamin C

What it is for

  • The health of the skin
  • Forming the enamel of teeth
  • Taking part in the synthesis of collagen fibres

Deficiency symptoms

  • Weakening of the gums
  • Internal bleeding
  • Slow healing of illness
  • Scurvy

Follow the connection

Vitamin C's main job is making collagen — the protein holding skin, gums and blood vessels together. What happens when it is not made shows up directly in the deficiency symptoms: weak gums, bleeding, and wounds that will not heal.
