Chemistry for Biology (structure of matter (elements (Atoms: smallest part…

- - - - electrons
        
        Bonding - to fill valence shells
        
        octet rule: 1st shell fills w/ 2 and the rest w/ 8
        
        valence electrons: participate in bonding
        
        bonding forms molecules- smallest particle of a compound w/ same properties of a compound (polar molecules- weakest)
        
        Compounds: combos of elements w/ different properties
        
        Covalent: (strongest) electrons shared, go around both atoms
        
        Ionic: (medium) electrons given/taken causes ions
      - nuetrons
        
        atomic mass of 1, no charge, in nucleus
      - protons
        
        in nucleus, +, have mass
- - - - fossilized
    - - short/medium term energy storage, structural parts of plants (cellulose), (chitin) in animals
    - - C, H, O, N
        
        structure of animals, enzymes, fast acting hormones, immune system
    - - genetic info storage, use DNA and RNA
    - - longterm energy storage, steroid hormones, cell membrane insulation
    - - dehydration synthesis: take H from 1 monomer and OH from another, allowing the monomers to join and make water
        
        necleic mono: nucleotides
        
        protein mono: amino acids
        
        all amino acids have an amine and carboxyl group
        
        20 amino acids are distinguished by R group
        
        carbohydrate mono: monosaccharides (simple sugrs)
        
        lipid mono: glyerol, cholesterol, fatty acids
        
        saturated fatty acids: not healthy (all C bonded w/ single covalent bond)
        
        unsaturated fatty acids: at least 2 Cs are double covalent bonded (healthy)
