module 5

• Carbohydrates

  good source of energy
• Components of Carbohydrates

  • Carbon
  • Hydrogen
  • Oxygen
• Functions of Carbohydrates

  • Give the body energy

  • Provide stored energy

  • Help preserve muscles

  • Promote digestive health

  • Influence heart health
• Monosaccharide

  end with the suffix -ose.

  they may be known as:

  • trioses (three carbon atoms),

  • pentoses (five carbon atoms),

  • hexoses (six carbon atoms).
• Disaccharides

  Two monosaccharide molecules “double sugar” bonded together through a dehydration synthesis reaction
• Polysaccharide

  A long chain of monosaccharide “poly means many” linked by covalent bonds.
• Lipids

  insoluble in water but are soluble in oil
• Function

• Functions of Proteins

  • motion
  • metabolism
  • movement of substances
  • regulation
  • defense
• Component of Protein

  • Amino Acids - organic compounds considered to be the building blocks of proteins
• Deoxyribonucleic Acid (DNA)

  Encodes and transmits inherited genetic information from one generation to the next

  Ribonucleic Acid (RNA)

  Translates the information encoded in DNA for the production of proteins and help in their synthesis
• Factors Affecting Enzyme Activity
