Question 4 (1 point) The amino acid Glutamine has a region of its R-group has a double-bonded O with a partial negative charge. What best explains the existence of this partial charge? H H3N-C-C=O CH2 CH2 C NH2 Glutamine (Gln / Q) O The positive charge of the amino group has to come from somewhere. O It has a significantly higher electronegativity then the C that it's bound to. O The electrons that the C and O share spend more time around the C atom. O It picked up an extra electron from another amino acid's R-group.

Step 1
This means that oxygen attracts electrons more strongly than carbon. In a double bond between carbon and oxygen, the electrons are shared between the two atoms, but they spend more time around the oxygen atom due to its higher electronegativity. This results in a Show more…

Question 7.7. All amino acids have a central carbon with four components attached to it. One of these components is called the R-group. Which of the following best describes the R-group? The R-group helps the amino acid replicate. The R-group gives the amino acid unique characteristics. The R-group is the same in all amino acids. The R-group is what stabilizes the amino acid.

Which amino acid takes on a positive charge when the R-group gains a proton? a. Glutamic Acid b. Tyrosine c. Histidine d. Glutamine e. Glycine
Rupsa S.
For amino acids with neutral R groups, at any pH below the pI of the amino acid, the population of amino acids in solution will have: A. no net charge. B. a net positive charge. C. a net negative charge. D. no charged groups. E. positive and negative charges in equal concentration.
