Looking Closer

This collection contains a wide variety of resources and information about Digestion Chemistry, which supports the resources in the other collections.

  • Hormonal control of digestion – Article

    The gut is the body’s largest hormone-producing organ, releasing more than 20 different peptide hormones, some of which have a key role in controlling food intake and energy expenditure.

  • Healthy gut bacteria – Article

    It has been estimated that there are more bacteria in the large intestine than there are cells in the body. Maintaining a healthy bacterial population in the large intestine plays a key role our sense of wellbeing.

  • Mitochondria – cell powerhouses – Article

    Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. Keeping them functioning well is key to avoiding premature ageing and degenerative diseases.

  • Digestive enzymes – Article

    Enzymes are globular proteins that control biological reactions. Digestive enzymes speed up the breakdown (hydrolysis) of food molecules into their ‘building block’ components. These reactions occur outside of the cells lining the gut.
