UNIT 1 Flashcards
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
