bcm1 extras Flashcards
typical length of a protein
30kda
what is the bohr model?
bdige between the planetry model and full quantum model, suggests electrons as waves
what is the wavelenth of an electron proportional to?
inversely proportional to their momentum
what is the de brogue equation?
shows that wavelength is inversely proportiona lt ot momentum
lambda= h/p
h= plancts constant
p = mass x velocity
what did the double split experiment show?
a wavelike interferance pattern
what is the principle quantum number of a 1s orbital?
n=1
what is the azimuthal quantum number of 1s?
represented by s no. (curvy bottom) L
what does the principle quantum number tell you?
how large the orbital is
how far the nucleus is from the outer most antinode
what does the asmithual quantum number tell you?
how nodes are distributed
doesnt exist for 1d string
what is the probability density?
how likely you are to find electrons from nucleus
in 1s probability decreases exponentially with distance from nucleus
what is the radial distribution function?
probability of finding an electron in spherical shell
what are spdfg?
common names for orbitals with particularly l values
what happens to solubulity of alcohols as chain lengh increases?
solubility decreases
what is lysergic acid?
alkaloid
what is an alkaloid
contain mostly basic nitrogen atoms
what are hemiketals and hemiacetyls?
ketones and aldehyes with addition of OH to carbonyl group
what group does chitin contain?
acetyl groups
where can quaternary ammonia be found?
choline phospholipid
where can primary ammonia be found?
alanine
where can secondary ammonia be found?
spermidine
where can tertiary ammonia be found?
trimethylamine
why are aromatic N’s weaker?
as lone pairs interact with annular pi bound in aromatic withdraw negative change, harder for proton to atttch
what are thiols properties compared to alcohols?
more acidic
reducing
reactive than alcohols
what is an example of an amino acid thiol?
cysteine
give an exampole of a thioeseter co enzyme?
acetyl coa
what is an imine?
a functional group or chemical compound containing a c=N bound
= basic
amine + aldehyde
what is an ether bond?
an oxygen atom connected to acyl or aryl group
what is an aryl group?
derived from aromatic ring
