Understand Meaning/Significance of Key Terms
significance of carbohydrates in physiology

Significance of Carbohydrates in Physiology




composition of carbohydrates
Composition of Carbohydrates
  • All of them, mono-, di- and poly- contain the elements C, H and O
  • The ratio of C:H:O is 1:2:1 or Cn(H2O)n OR CnH2nOn where “n” may be 5, 6 or …
  • If n=5 then a monosaccharide will most likely have the formula C5H10O5
classes categories of carbohydrates
Classes/Categories of Carbohydrates
  • Monosaccharides
  • Disaccharides
  • Polysaccharides
  • Examples of each?
  • Examples of monosaccharides
    • Glucose
    • Fructose
    • Galactose
  • They each have 6C, therefore called hexoses
  • What would be the chemical formula for each one?
  • Looking at the structural formula for Glucose, Would you expect it to be:
    • Hydrophilic? OR
    • Hydrophobic?
significance of monosaccharides in physiology
Significance of Monosaccharides in Physiology
  • They are fuels
  • Body cells “burn” or “Oxidize” these fuels in order to extract from them ENERGY
  • Cells burn fuels by a process called:
    • “Cellular Respiration”
  • A general formula for “cellular respiration”
    • Fuel+ nO2 nCO2 + nH2O + Energy
  • Energy will be in the form of
    • Heat plus a chemical called nATP
  • By what process do monosaccharides get into/out of cells? (Study Guyton Ch.4)
  • Examples of disaccharides
    • Sucrose
    • Lactose
    • Maltose
  • Composition of sucrose
    • Glucose + Fructose joined by a glycosidic bond
  • Composition of Lactose
    • Glucose + Galactose joined by a glycosidic bond
  • Compsition of Maltose
    • Glucose + Glucose joined by what?
dehydration synthesis
Dehydration Synthesis
  • The type of chemical reaction by which disaccharides are produced is called:

Dehydration synthesis

  • Formation of covalent bond requires participation of an enzyme and consumes energy
  • Questions?
    • Is dehydration synthesis an example of anabolic or catabolic metabolism?
    • Does it consume or yield energy?
significance of disaccharides in physiology
Significance of Disaccharides in Physiology
  • We get them in our diet when we
    • drink milk or malt,
    • or eat sugar cane or use table sugar or run on “Dunkin”
  • They are synthesized by cells BUT there are no mechanism/process by which they can enter body cells
  • So what happens to disaccharide when we consume them? (Study Guyton Ch. 65 p789-93; p793-97)
  • All chemical reactions that occur in cells

Examples: Dehydration Synthesis, Hydrolysis plus those in metabolic pathways (glycolysis & Krebs Cycle)

  • Types of metabolism
    • Anabolic
    • Catabolic
  • Anabolic:
    • For building up big and complex molecules
      • i.e., anabolic steroids are consumed by weight lifters
  • Catabolic: For breaking down big and complex molecule into simpler ones
anabolic vs catabolic metabolism
Anabolic vs Catabolic Metabolism
  • Anabolic
    • Net consumption of energy
    • Covalent bonds are synthesized
    • Example:???
  • Catabolic metabolism
    • Net yield of energy
    • Covalent bonds are broken
    • Example:???
  • Both require participation of enzymes
anabolic vs catabolic metabolism illustrated marieb ch 3
Anabolic vs Catabolic Metabolism: Illustrated (Marieb, Ch. 3)

Which one illustrates

catabolic metabolism:

a, b or c?

glycogen a polysaccharide
Glycogen: A Polysaccharide

What monosaccharide is the building block for glycogen?
