up HIV protease by binding to it (suicide inhibitor).
7) Merck chemists modified the structures to increase their water solubility by
introducing a side chain.
2.1 CARBON–CARBON COVALENT BONDS
- Carbon forms strong covalent bonds to other carbons, hydrogen, oxygen, sulfur,
and nitrogen.
- Provides the necessary versatility of structure that makes possible the vast
number of different molecules required for complex living organisms.
- Functional groups:
2.2 HYDROCARBONS: REPRESENTATIVE ALKANES, ALKENES,
ALKYNES, AND AROMATIC COMPOUNDS
- Saturated compounds: compounds contain the maximum number of H
atoms.
- Unsaturated compounds:
2.2A ALKANES
- The principal sources of alkanes are natural gas and petroleum.
- Methane is a major component in the atmospheres of Jupiter (木星), Saturn (土
星), Uranus (天王星), and Neptune (海王星).
- Methanogens, may be the Earth’s oldest organisms, produce methane from carbon
dioxide and hydrogen. They can survive only in an anaerobic (i.e., oxygen-free)
environment and have been found in ocean trenches, in mud, in sewage, and in
cow’s stomachs.
