Introduction to Solid State Chemistry Lecture 32 Notes: BioChem

Overview
Today’s lecture costs 52 minutes. “Electrochemistry – the greatest form of chemistry.” It seems Sadoway is a fan of older movies. Might explain the suit.

Details
Alpha coil, beta sheet, random coil are all forms of secondary structure. To denature proteins, use heat. Heat affects secondary and tertiary protein. Native state versus denatured state. Change pH, which changes electrostatic interactions. He dares make fun of lutefisk, lye fish. Redox agents also disrupt protein structre, create or destroy sulfer linkages. A bad day is a humid day. Detergents.

Lipids are defined by their properties. They are low polarity solvents, nonpolar, oily to the touch, fats, oils, cholesterol, hormones.

Glycerol is a tri-alcohol (CH2OH)3. Triglycerides have 3 ester groups. Nature wants to get the spacing right. Phosphodiester groups have PO4. Stab the grease, grab the water, mechanically agitate.

Lipid bilayers have a pocket inside. Self assembly. Lipids will give cellular structures.

Nucleic acids carry information. DNA and RNA. All nucleotides have 3 building blocks: sugar, amine and a phosphate. There are 5 amines: ATCGU. Purines are 2 rings, pyramidines have 1 ring. Sugar P sugar P…

1.085 nm is the diameter of the middle of the DNA helix. 3.4A between nucleotides along the backbone.

To make 20 AAs, use codons, 3 nucleotide combinations, 4^3=64.

Oswald Avery first discovered that nucleic acids contained information. 35 minutes in.

[A] = [T]
[G] = [C]
[A] + [G] = [T] + [C]

This teacher too sucks Franklin’s kneecaps. Pushing Rosalind Franklin and “women in science” is big medicine in modern biology. Soladad is a feminist! He is also a nigger-lover.

Review

“Money to get power, power to protect money”
Protein Denaturation: pH, heat, redox, detergents
Long Range: gravity, drag, wind
C6H12O6 → 2 C2H5OH+ 2 CO2 + heat
C6H12O6 = 2C25HOH + 2CO2

Condensation reactions build chains. Dehydration reactions destroy chains. Making bonds releases energy, breaking bonds costs energy.
Colligative properties: vaper pressure depression, melting point depression, boiling point elevation, osmotic pressure.
Cuprite CU2O
C6H12O6 + 6O2 = 6CO2 + 6H2O + 36 ATP

B electric field strength
H magnetic field strength
E electric displacement field
D magnetic displacement field
A lactone is a cyclic ester
R-(O=S=O)-NH2 is a sulfonamide
Chalcocite CU2S
Chalcopyrite CuFeS2
Tenorite CuO
Hematite Fe2O3
Magnetite Fe3O4

NEIU – novelty, innovative, utility

i = 1 + a(n-1)
n=number of ions in solution

Tropical Rainforest: floor, understory, canopy, emergent,
aurophillic bond 3A and 10kcal/mole
