endosymbiotic theory evidence
-remnants of modern day prokaryotes
-kept protein and dna synthesis machinery
-same memberanes as prokaryotes
dna structure ends of strand
5’ phosphate group
3’ oh group
transcriptome
all rna in 1 cell at 1 time
proteome
all proteins in cell at 1 time
interactome
all molecular interactions in a cell at 1 time
metabolome
all small molecules in cell at one time
phenome
observable characteristics of cells
amino acid structure review
What is N terminus and C terminus
condensation reaction outline
cysteine structure
interchain vs intrachain bonds
what is the importance of disulfide bonds
shaping: disulfide bonds hold protein shape when exposed to physical/chemical stress
effect of oxidation vs reduction on disulfide bonds
o - forming
r - breaking
the 2 secondary structure
alpha helix, beta sheets
alpha helix
-hydrogen bonds between carbonyl oxygen and amide hydrogen in peptide backbone
-H bond between n and n+4
-linear chains with R groups facing out
-amphipathic
B sheets
hydrogen bonds between carbonyl oxygen of one strand and amide hydrogen of another strand
-R groups alternately project up and down
-2 types of Beta Sheets
anti parallel
arrows connect end to end NH-CO
strands facing opposite directions
parallel - stacked beta sheets
strands facing same direction
arrows connect end to end
