1 Organic Chemistry

2 What is Organic chemistry?
Historical “Organic” – derived from living organisms Compounds such as sugar, urea, starch Vitalism: natural products needed a “VitalForce” to create them Wöhler (1828) synthesis of urea Inorganic Organic

3 Organic Chemistry Today
The study of compounds and reactions involving carbon, regardless of source (Kekulé, 1861) Organic Chemistry: The chemistry of carbon and carbon-based compounds

4 Why should we care? Biochemistry Pharmaceuticals Industry Polymers
Explosives

5 Organic Chemistry in everyday life:
Smells & tastes: fruits, chocolate, fish, mint Medications: Aspirin, Tylenol, Decongestants, Sedatives Addictive substances: Caffeine, Nicotine, Alcohol, Narcotics Hormones/Neurotransmitters: Adrenaline, Epinephrine Food/Nutrients: Carbohydrates, Protein, Fat, Vitamins Genetics: DNA, RNA Consumer products: Plastics, Nylon, Rayon, Polyester

6 Organic Molecules

7 the brain dopamine

8 Synaptic neurotransmission
Dopamine neuron Target Neurons terminal dendrite cell body axon postsynaptic receptor presynaptic dopamine transporter vesicles tyrosine l-dopa synapse

9 a neurotransmitter present in the brain
Dopamine a neurotransmitter present in the brain a space filling model

10 a neurotransmitter present in the brain
Dopamine a neurotransmitter present in the brain nitrogen hydrogen oxygen carbon a ball and stick model

11 Dopamine

12 Dopamine. Dash Molecular formula
two lines = 4 electrons one line = 2 electrons Condensed molecular formula = C8H11NO2

13 Dopamine. Line-Angle Molecular formula
all nodes are carbon add hydrogens until there are 4 bonds to each carbon atom

14 Both structures represent the molecule dopamine but the bottom structure is simpler to draw.

16 Chemical Formulae Empirical formula Molecular formula Example:
Smallest integer ratio between atoms of different types in a molecule. Molecular formula Actual number of atoms of each type in a molecule. Example: Ethene (C2H4) and cyclohexane (C6H12) both have the empirical formula (CH2)
