UNIT 1 Flashcards
(19 cards)
definition of biochemistry?
chemical application to biological processes, cellular +molecular level
what are the 3 types of biochemistry?
- structural
- metabolism
- molecules+processes store and transmit information
what is structural biochem?
study of relationship between structure+ function in life molecules
what is metabolic biochem?
study of total chemical reactions in living organism
what is .molecules+processes store and transmit information biochem?
study of transmission of genetic information
flow of dna + atp in living organisms is?
dna>rna>protein + atp the same in all living organisms
what is vitalism?
organic chemicals ONLY MADE by living organisms
what did Avery discover? (2)
nucleic acids = info
catalytic action of enzymes
what did Watson + crick discover?
3d DNA
what is a sythentic pathway?
route taken to build product = anabolic
what is the order of biochem?
Atoms
Biomolecules
Macromolecules
Cellular structures
How the cell synthesizes these
macromolecules?
modular approach= monomers–> polymers
MONOMERS>MACROMOLS>MACROMOL COMPLEX?
Monomers (sugars, aminoacids, nucelotides) COV BONDS-> (macromol e.g RNA)–> NON COV macromolcomplex
why is biochemistry important for dental students? (3)
- teeth composition
- saliva= de/remineralisation, amylase, ph (water)
- bacteria in oral cavity =bibofilms using sugars in food
which top biomolecules encode+ transmit info? (3)
- nucleic acids - dna
- proteins= hormones + immunoglobulins
- Neurotransmitters -between cells
Wöhler in 1825 demonstrated what?
that urea, could be
synthesized in the lab from an
inorganic compound.
Eduard Buchner (1897) observed what?
yeast extracts could ferment sugar to ethanol
Frederick Kühne gave the name to what?
enzymes to the molecules detected by
Buchner.
4 types of macromolecules?
- lipds
- proteins
- carboydrates
- nucelic acids
