Thread of Life Flashcards
What does a rate equation look like?
Rate = k[A]m[B]n
How do you work the overall order of a reaction?
m+n
On a graph that shows the rate of reaction plotted against A, what would zero, first and second order look like?
Zero order = horizontal line showing rate is independent with respect to A
First = rate is proportional to A
Second = a curved line that would appear straight if plotted against A2
What is a rate determining step
The slowest step in a reaction
What is an isomer?
Same molecular formula be different arrangements of their atoms in space
Are natural animo acids L of D shaped?
L
What is an enantiomer?
A single optical isomer
In TLC what types of compounds does UV light show?
Aromatic rings
How would you show up amino acids in TLC
Add ninhydride and heat
Explain the term the zwitterion
contains a positive charge and a negative charge
Why will one stereoisomer of a drug work but not another
only one with correct shape bind to the active site
explain how a compound is chiral
4 different groups around a C atom
so that they are not superimposable on their mirror image
what two structure prevents the rotation leading to cis-trans isomeristaion
rings and double bonds
What is secondary structure
Folding of polypeptide chains
What is tertiary structure
3D structure
