|
What are the branched chain amino acids (that are not degraded in MSUD syndrome)?
What are the two negatively charged amino acids? |
Valine, Isoleucine, Leucine
Aspartate and Glutamine |
|
|
What three amino acids are positively charged (hint: two of them are ideal for binding negatively charged DNA to help it condense)?
What is the smallest amino acid? What amino acids creates kinks in 3D conformation because of it's odd side chain? |
Arginine, Histidine, and Lysine (note: Lysine and arginine are main parts of Octamer)
Smallest = Glycine (also an inhibitory NT), Proline has strange side chain so it can create kinks in side chain |
|
|
What three amino acids have aromatic side groups?
Which amino acids are frequently phosphorylated? What amino acid is an INTEGRAL part of the inuslin molecule structure? |
Aromatic = phenylalanine, Tryptophan, tyrosine
Phosphorylation= Serine, Threonine, Tyrosine (all have OH and can also undergo O-glycosylation). Insulin- has disulfide bonds --> Cysteine |
|
|
6 amino acids with NONPOLAR side chains?
Which amino acid is critical for the NE to Epinephrine transition? |
Glycine, Proline, Alanine, Valine, Isoleucine, Methionine
Methionine! Helps donate the CH3 that is used to make epinephrine. |
|
|
Glutamine vs. Glutamate?
|
Glutamine = Glutamate + an NH3 (note: it is a POLAR uncharged side group and can happily float through the blood without fear of changing pH)
vs. Glutamate = a negatively charged side group which can also contribute to pH change so it does not get passed through the blood |
