Week 2 Flashcards
if pH < pKA
we protonate, add an H+
proline has a
imino bond
non spont require
input of energy
spontaneous
increase in disorder, increase in S. doesnt require input of energy
going from 2 reactants to 3 products
increasing disorder. delta S is positive, so delta G is negative.
__ and ___ fundamental to life
genetic information and free energy
cell requires
free energy, imported from surroundings
polar covalent bond
unequal sharing of electrons.
dideoxynucleotide
cant form another nucleotide
out of a reaction comes out
condensation reaction (water) and ppi (pyrophosphate
most structurally complex molecules?
proteins
protein has
three dimensional structure
two types of beta sheet structures in proteins
antiparallel and parallel b sheets.
amino acids are joined by
peptide bonds. bw carboxyl group of one amino acid and the amino group of another amino acid.
non covalent bond
NO SHARING OF ELECTRONS
form leads to
function
pH of human body
7.2-7.4
pKA means
equilibrium bw reactants and products
OH groups
can be phosphorylated
o linked
OH group (Ser, Thr) site for attachment of carbohydrates
non polar molecules found where?
phospholipid bilayer. they are integral proteins-proteins in membrane.
Met (M) is (almost always)
first amino acid translated (AUG codon = Met)
Cys can form
covalent disulfide bond by oxidation ( -C-S-S-C- ). only covalent linkage that creates tertiary structure.
