intro to biological molecules Flashcards
1
Q
5 important molecules in living things
A
carbohydrates (energy)
proteins (growth and repair)
fats (insulation)
water (metabolic reactions)
nucleic acids (form DNA/ RNA)
2
Q
what elements can carbon bond with
A
hydrogen, nitrogen, sulfur, oxygen
3
Q
what do organic compounds contain
A
carbon and hyrogen
e.g. carbs, lipids, proeins, nucleic acids
4
Q
3 types of bonds
A
covalent
ionic
hyrdrogen
5
Q
intramolecular
A
within the bonds (strong)
6
Q
intermolecular
A
connected to the other bonds (weak)
7
Q
condensation reaction
A
monomer + monomer = polymer + h20
8
Q
hyrolysis reaction
A
polymer + h20 = monomer + monomer
9
Q
macromolecules
A
very large molecules (1000+ atoms) so high molecular mass
