  1. 1. Nutrition<br />
  2. 2. The food that we eat contains ……<br />Carbohydrates<br />Proteins<br />Fats / Lipids<br />Vitamins<br />Minerals<br />Water<br />
  3. 3. Carbohydrates<br />The basic structure of all carbohydrates is the same. They are made up of carbon, hydrogen and oxygen.<br />
  4. 4. Types of carbohydrates<br />There are three main groups of carbohydrates, depending on the complexity of the molecules.<br />monosaccharides<br />disaccharides and <br />polysaccharides<br />
  5. 5. Monosaccharides<br />Glucose<br />Fructose<br />Galactose<br />Ribose sugar <br />De-oxy ribose sugar<br />
  6. 6. Disaccharides<br />Disaccharides are made up of two monosaccharides joined together.<br />Two monosaccharides join in a condensation reaction.<br />The link between two monosaccharides results in a covalent bond known as glycosidic bond.<br />
  7. 7. Condensation Reaction<br />Monomers are joined by condensation reactions, which release a molecule of water for each bond formed. <br />
  8. 8. Hydrolysis<br />Hydrolysis reactions use water to break polymers into monomers.<br />
  9. 9. Disaccharides<br />Maltose = Glucose + Glucose<br />(Found in germinating seeds such as barley)<br />Sucrose = Glucose + Fructose<br />(Stored in plants such as sugar cane)<br />Lactose = Glucose + Galactose<br />(Carbohydrate found in milk)<br />
  10. 10. Polysaccharides<br />Made up of many monosaccharide units<br />Starch<br />Cellulose<br />Glycogen<br />
  11. 11. Activity<br />What did we learn ?<br />Construct a table with types of carbohydrates and examples for each<br />
  12. 12. Activity<br />What did we learn ?<br />Make a chart showing condensation reaction<br />
  13. 13. Proteins<br />
  14. 14. Proteins<br />Proteins are formed by joining amino acids.<br />Two amino acids are connected by a peptide bond<br />There are 20 amino acids found in humans. <br />Examples of proteins<br />Enzyme<br />Hormones<br />Antibodies<br />
  15. 15. Hemoglobin<br />
  16. 16. Proteins are denatured by <br />heat, <br />alterations in pH<br />They lose their shape and won’t be able to do their functions<br />
  17. 17. Lipids<br />Lipids are water insoluble macromolecules.<br />Fats and oils are triglycerides, composed of three fatty acids covalently bonded to a glycerol molecule by ester linkages.<br />
  18. 18. Saturated lipids<br />Saturated fatty acids have a hydrocarbon chain with no double bonds. <br />
  19. 19. Unsaturated lipids<br />The hydrocarbon chains of unsaturated fatty acids have one or more double bonds that bend the chain, making close packing less possible.<br />
  20. 20. Phospholipids<br />Phospholipids have a hydrophobic hydrocarbon "tail" and a hydrophilic phosphate "head." <br />
  21. 21. Activity<br />What did we learn ?<br />Write down the three major food components and what will we get when we digest them<br />
  22. 22. Activity<br />What did we learn ?<br />Write down what are the following<br />
