Ch 1 - Bio Chemistry Flashcards
What elements do Carbohydrates and proteins have in common?
What element separates out proteins from carbs?
C H N O
C H N O S - Sulfur
What are the polysacharrides of starch
amylose - 1-4 glycosidic linkages of Glucose
amylopectin - 1-4 glycosidic linkages and 1-6 glycosidic linkages (Like Glycogen but less branched)
What is a nucleon?
Proton or Neutron
Are soluble protein’s electrostatic interactions stronger internally or externally?
Internally - The water hydrogen bonds create an solvent shell that weaken the electrostatic interactions
-ΔG means?
Spontaneous reaction (exergonic)
+ΔG means?
Non-Spontaneous reaction (endergonic)
ΔG = 0 means?
The reaction is at equilibrium
Are almost all exothermic reactions spontaneous or non-spontaneous?
Spontaneous
-ΔH and +ΔS means what?
The reaction will be spontaneous regardless of temperature
ΔG = ΔH - T ΔS
Open System
mass and energy can exchange
Closed System
allows energy to transfer, but not mass
Isolated System
Neither energy nor mass can transfer
Chemotroph
Derive free energy from the oxidation of fuel molecules
Biotin
Biotin is a cofactor involved in carboxylation and decarboxylation reactions.
Transfers CO2
Used in Glycolysis
S-Adenosylmethionine (SAM)
CoFactor involved in CH3 (methyl) group transfers
