- Cells can divide, grow, convert energy, respond to stimuli, evolve
- Macromolecules: carbohydrates, proteins, lipids (covalent bonds between
monomers)
Lecture 2:

- No. of electrons in the first 3 shells: 2, 8, 8
- Bonds that join atoms:
1. Covalent: involves the sharing of electron pairs between atoms
= Non-polar: same electronegativity
= Polar: different electronegativity
2. Non-covalent
= Ionic bonds
= Dipole-dipole: uneven sharing of e
= Hydrogen bonds: with oxygen or nitrogen
= Va der aal’s: e i rado otio
= Hydrophobic interactions
= Coordinate links: metal ion and metal atoms
