Room: E300
Chapter 1 through 3
Electronegativity and Equilibrium are atoms affinity one attraction.
Table 3.2
A summary of protein structure: Primary, Secondary, Tertiary, and Quaternary...description and stabilized by?
Primary is a Peptide bonds that has a chain of "Gly--Ser--Asp--Cys".
Secondary (looks like a plateau with rail lines across of it is denatured (unfolded).
Tertiary is unable to function normally.
Quarternary's molecular chaperones.
Table 3.3
A summary of protein functions.
Protein types are Antibodies and compliment protein; contractile protein and motor protein; enzymes; peptide hormones (insulin); receptor protein; structural protein; transport protein.
Also, their "roles in cell or organism.
Between Peptide and Steroid hormones.
Intro to Catalysis:
Catalysis lowers the activation.
Catalysts do not change DeltaG and are not consumed in the reaction. DeltaG, a free energy.
Activation energy E (Subscript A) Ea. (Provides a barrier).
Transition (something in between).
A - B - C
Transition State
Protein becomes enzyme which becomes amino acid.
A model of enzyme action.
Termination
Cofactors Coenzyme
Substitute sets in before heading home.
Make Allostar. (Damn I was probably sleeping in class that's why have no idea what I wrote here.)
Nucleotides (nt) are monomers.
DNAs 1 degree structure = sequence of nitrogenous bases, which contain info. DNA's 2 degree structure running in oppositve directions. Complimentary base pairing double helix.
RNAs 1 degree structure also consists of a sequence. 2 degree structure includes short double.
What is Nucleic Acid?
It is the RNA world of the ability to reproduce and the metabolism polymer of nucleutides.
Ribose
Sugar difference, instead it has Ribose.
Deoxyribose
Nitrogen containing basis.
Cytosine
Nucleotide, a phosphate group. 5 Carbon Sugar. Nitrogenous base.
How do Nucleotides polymerize to form Nucleic Acids?
Condensation reaction
Phosphodiester linkage.
Ribonucleic Acid (RNA) is made from ribonucleotides.
DNA, Deoxyribonucleic Acid is made from deoxyribonucleotides.
Table 4.2 Using Rosalind Franklin's data.
DNA structure and function. Watson and Crick Model. Two anti parallel DNA strands double.
Purine - Pyrimidine.
Hydrogen Bonds?
Guanine and Cystosine: 3 Hydrogen Bonds
Adenine and Thymine: 2 Hydrogen Bonds
Hydrogen is keeping these two together. Guanine needs higher temperature to break because it has too much double helix and double hydrogen bonding.
DNA contains thymine.
RNA contains uracil.
If denatured, how can it be renatured?
What kind of molecule is it? Stable Molecule.
What came first RNA or DNA?
RNA because it's a single stranded. RNA contains uracil, not thymine. RNA can take entriquet structure. RNA can replicate. DNA is double cannot replicate.
Chapter 5: Carbohydrate
Glucose + Glucose = Maltose
Glucose + Galactose = Lactose
Glucose + Fructose = Sucrose
Amylose is in saliva.
Starch is a1.4
a1.4 glucosidic linkage.
Polysacharide
Glycogen is highly branched.
Cellulose: A structural polysacharide in plants.
Alternate flipping of glucose monomers allows extensive hydrogen bonding.
Chitinnacetyl glucosamine is Fungi + Algae.
Mono, poly, disaccharides.
Glycolipids
Glycoprotein
CHO (Carbohydrate) as Electron Donors.
Carbondioxide + Water + Sunlight gives Carbohydrates + Oxygen. Carbon was reduced.
If reversed, we can make ATP.
Polar interacts with water.
