Food and Food Tests | Definitions
Structural Role of Biomolecules
The function/job/involvement of carbohydrates, lipids, proteins and vitamins in making various parts of an organism.
Trace Element
Minerals needed in small amounts in the body, e.g. iron, zinc and copper.
Biomolecule
A chemical substance made in the cells of a living organism.
Monosaccharide
A single sugar molecule.
Disaccharide
A carbohydrate consisting of two monosaccharides joined together.
Polysaccharide
Many monosaccharide molecules joined together.
Anabolic Reaction
A reaction that absorbs energy to make bigger molecules from smaller ones.
Catabolic Reaction
A reaction that releases energy to break down bigger molecules into smaller ones.
Fats
Lipids that are solids at room temperature.
Metabolic Role of Biomolecules
The function/job/involvement of carbohydrates, lipids, proteins and vitamins in the chemical reactions that occur in cells that make various substances organisms require.
Metabolism
The sum of all the chemical reactions that occur in an organism.
Oils
Lipids that are liquids at room temperature.
Qualitative Test
A test that records the presence or absence of a substance. It is a yes or no question.
Vitamins
Biomolecules that are essential organic catalysts of metabolism.
