Biochemistry
Study of properties of individual molecules within a living system & how they interact with one another
What is the purpose of biochemistry?
It seeks to describe the organization & function of living matters in molecular terms
What are the 3 disciplines of Biochemistry?
1. Structural
2. Metabolism
3. Genetic / Molecular Genetic
Explain the Structural discipline.
Focus on components & relationship of biological function to chemical structures
Explain the Metabolism discipline.
Totality of chemical reaction in living matter.
Explain the Genetic / Molecular Genetic discipline.
Chemistry of storage and transmission of biological information.
What are the 3 properties that makes a collection of molecules a living system?
1. highly organized set of complex molecules that result in complicated structures with intricate internal structure
2. each component of a living organism has a specific purpose
3. ability to extract, transform, & utilize energy from the environment to build & maintain structures, work, move, reproduce, ect
Of the 3 properties of a living system which is the most important?
3. ability to EXTRACT, TRANSFORM, UTILIZE ENERGY from environment to BUILD, MAINTAIN STRUCTURES, WORK, MOVE, REPRODUCE, ect
What are viruses considered as?
biological entities = parasite
what are the 4 basic groups of biomolecules?
nucleic acid / proteins/ lipids / carbohydrates
Of the 4 basic groups of biomolecules which actually carry information?
protein, nucleic acid, and some times carbohydrates
What are the 4 basic structures of a cell?
plasma membrane / cytoplasm / genetic material / ribosomes
Adenine; purine
Guanine; purine
Uracil; pyrimidine
Thymine; pyrimidine
Cytosine; pyrimidine
Ribose
Deoxyribose
what are the 3 types of systems in thermodynamics?
open / closed / isolated
What are the difference between the 3 different types of thermodynamic systems?
Open allows for both matter & energy to be exchanged; Closed allows only energy; Isolated does not allow matter nor energy to be exchanged
State function
thermodynamic variable use to describe the thermal dynamics state of the system
How is a state function determined?
by initial & final state of the system and independent of the pathway in between the 2 states
What are some examples of state function? What is not a state function?
Temperature / pressure / [solute]/ gibbs free energy / enthalpy / entropy

Not state function = work done
Spontaneous reaction (favorable)
irreversible process that is far from equilibrium
What are the 1st and 2nd law of thermodynamics?
1. law of conservation
2. total disorder of universe increase in every process
What are the 7 non-covalent interactions?
h-bond / charge-charge / charge-dipole / dipole-dipole / charged-induced dipole / dipole-induced dipole / London
Hydrogen bond (3 requirements)
1. N/O/F/S
2. must have lone pair of e-
3. strongest is linear 180 degrees +/-45 exist
Charge - charge interaction

electrostatic / ionic interaction between molecules/atom with permanent charge; nondirectional
Charge - dipole interaction
between a charged species and 1 dipole; directional
between a charged species and 1 dipole; directional
dipole-dipole
interactions between 2 molecules with a permanent dipole; directional
interactions between 2 molecules with a permanent dipole; directional
charged-induced dipole
polarizable molecule (e- are displaced to give momentary charge) placed near a charge molecule; a dipole will be induced with charge; non-directional
polarizable molecule (e- are displaced to give momentary charge) placed near a charge molecule; a dipole will be induced with charge; non-directional
