I
organic synthesis:how chemists create molecules

first synthesized molecule by Friedrich Wohler (1828) was Urea


now almost every molecule can be synthesized
taxol (anti-cancer drug) can now be synthesized in 51 steps

supramolecular chemistry:
molecular chemistry/organic synthesis creates molecules through covalent bonding
supramolecular chemistry (1960s) creates by noncovalent bonds
complex

new properties & powerful tool to make large structures


supramolecular chemistry:'chemistry beyond the molecule

held together by reversible intermolecular forces

supramolecular chemistry usuallyin thermodynamic control, organic synthesis
predominantly Kinetic control
supramolecular chemistry inspired by nature


enzymes:catalyze organic reactions by bind
-




ing 2 different
molecules

lowers transition state, accelerating
the organic reaction


breakdown reaction:One molecule is bound


by the enzyme into a new components
and is split

lock and key principle:enzymes are extremely selective (act as a


lock only to be 'openedby its key moleculel

there's a complimentarity between 'lock' and 'Key'
sterically:shape-wise

electronically:sites of electron richness in a molecule is

in the
complemented with low electron density enzyme

Host:ligand, enzyme, receptor, antibody (lock)
Guest:metal substrate, drug, antigen (key)

proteins (folding peptides (
primary structure of a protein:different amino acids forming
a polymer

secondary structure:polymer is folded

can be folded in a helix
or sheats (both stabilized

by hydrogen bonds


Quatemary structure:hemaglobin

double helix
DNA

basepairs:(adenine & thyminel &

(guanine & cytosinel
With it-T and hydrogenbond interactions

valinomycin:
ions are transported through a membrane (apolar) with macro-

cycles like valinomycin
valinomycin is a polar outside, and inside able to bindions


very selective for calcium (binds 1000x
better to potassium than

Sodium)

non-covalent bonds

in supramolecular chemistry, several non-covalent bonds

often operate simultaneously
