2 Biochemistry (Lecture) Flashcards
Atoms
Fundamental unit of matter made of sub atomic particles
Protons
In the neucleous always have posative charge
Neutons
in the neucleous no charge
Electrons
orbit the neucleus always have negative charge
Elements
Determineid by the number of protons
Ions
an atom that has gained or lost an electron
Cation
lost and electron posative
Anion
gained an electron negative
Electrolytes
an ion in water
Natrium =
Sodium
Kalium =
Potassium
Hyper Kalemia =
High potassium
Elements of the Body “CHOPNS”
Carbon, Hydrogen, Oxygen, Potassium, Nitrogen, Sodium
XXX Isotopes
Atom that has gained or lost an electron
Radioisotopes are used in medicine 2 ways
Imaging and Chemotherapy
Molecules
IE; CO2 H2O
Macromolecules
billions of molecules IE; DNA
XXX Acids
any component that releases Hydrogen ions is an acid H+
Bases
Releases hydroxide ions OH-
Neurtal pH
7.0
Normal body pH
7.4 blood
Buffers
anything that removes acid
Major organic compounds
Lipids, Carbohydrates, Protiens, Nucleic Acids
What is the most abundant organic compound
Carbohydrates
Where are carbohydrates produced
in photosynthesis
Fuel source for most cells
carbohydrates
suffix “ose”
means sugar (glucose, maltose, lactose)
