Organic Molecules

Molecules of LifeMolecules of our Food

organic food molecules
Organic (Food) Molecules
  • Found in and produced by living organisms
  • Large and complex
  • Carbon to carbon “backbones” - C – C – C - C
organic molecules3
Organic Molecules
  • Proteins
  • Carbohydrates (sugars and starches)
  • Nucleic Acids (DNA & RNA)
  • Lipids (Fats & cholesterol)
proteins
Proteins
  • Polymers of amino acids
  • Polymer –
  • Monomer –
proteins5
Proteins
  • Build an amino acid:

Proteins

Q: How do amino acids combine to form proteins?

A: Dehydration Synthesis

Proteins
  • Q: Are cow proteins identical to human proteins?
  • Q: Are cow amino acids identical to human amino acids?
who makes amino acids
Who makes Amino Acids?

Answer:

  • What simple inorganic molecules do they use?

proteins10
Proteins
  • FUNCTIONS OF(How are proteins used in living organisms?)
  • Silk of spider web
  • Enzymes (protein catalysts; “helper” molecules
  • Animals: hemoglobin (blood protein, carries O2)
  • Some hormones are proteins (e.g. insulin)
  • Some structures are proteins (hair, nails)
carbohydrates
Carbohydrates
  • Monosaccharides, a.k.a
  • Disaccharides, a.k.a
  • Polysaccharides, a.k.a
carbohydrates13
Carbohydrates
  • Monosaccharides

ex: GLUCOSE!

Carbohydrates

GLUCOSE

  • Who makes glucose?
  • By what process?

Carbohydrates

GLUCOSE

  • Who uses glucose? Why?
  • By what process?
  • Where is it broken down?

Carbohydrates

Disaccharides

carbohydrates disaccharides
Carbohydrates(Disaccharides)

SUGAR MATH!

Lactose = Glucose + Galactose

Maltose = Glucose + Glucose

Sucrose = Glucose + Fructose

Carbohydrates
  • Polysaccharides

Extension to Carbohydrates:

And now, what about insulin?
