What are nutrients?
Any substance that is used in the body for growth, energy and survival
What is metabolism?
The building and breaking down the various nutrients that animals ingest
The six categories of nutrients are…
Water Carbohydrates Lipids Proteins Vitamins Minerals
What is an essential nutrient
Nutrients that must be added from an external source
Four categories of essential nutrients
Essential amino acids
Essential fatty acids
Essential vitamins
Essential minerals
Where do carbohydrates come from?
Plants and milk
What is an important aspect of metabolizing carbohydrates?
To form glucose
What is glucose?
A monosaccharide fuel that cells need to generate ATP
What two cells exclusively use glucose as fuel?
Erythrocytes and neurons
True or False: Canines and felines need to ingest large amounts of carbohydrates
False
Canines and felines can receive an adequate amount of sugar from proteins and fats
What can glucose be converted into when not used as energy or stored as glycogen?
Glycerol and fatty acids
Characteristics of lipids
Poor water solubility
Cannot bind to polar ends
Lipoproteins
Utilized by the body to transfer lipids in the blood
Can easily carry free triglycerides and cholesterol in the bloodstream
What is the main structure that absorbs lipids in the small intestine?
Lacteals
Neutral fats
Stores energy and fat-soluble vitamins
Cushions and insulates organs
What vitamins are water-soluble?
Vitamins B and C
What are the fat-soluble vitamins?
Vitamins A, D, E, K
Phospholipids
Forms the phospholipid bilayer of cell membranes
