Question

Please help me, I am deeply confused in this class and trying so hard to understand. Please give detailed answers. I know some of these might be confusing but your help will really help me learn. The teacher requires very very detailed answers and he gives nearly no (and I mean literally nearly zero) partial credit so I'm dying here. Thank you sooooooo much, you have no idea.

Also, I am nearly leaglly blind and I am dyslexic so if you could please write clear it would help so much. I just want to learn like everyone else. SUPER SUPER THANK YOU

1. For each of the amino acids listed below, pick two of the three groups of terms and indicate which option applies to the side chains (R groups) of each. For example: Positively charged and hydrophobic. Another example: hydrophilic and small (4.5 pts total) Group 1 Positively charged/Negatively charged Group 2 Hydrophilic/Hydrophobic Group 3 Bulky/Rigid/Small [0.5 pt each] A. Pro B. Glycine C. K For the next two, also indicate and label the parts of the molecule that confer the two attributes you have listed [1.5 pts each] NH2 COO NH3 ??

Explanation / Answer

Ans.

A. Proline - hydrophobic and rigid

B. Glycine - hydrophobic and small

C. K (Lysine) - Positively charged and hydrophillic

D. Leucine - hydrophobic and bulky (the alkyl side chain consisting of 4 carbon atoms is bulky and gives the amino acid a hydrophobic nature as it does not have any polar group)

E.Tyrosine - hydrophillic and bulky (the phenyl group in the side chain is bulky and the hydroxyl group confers the hydrophillic properties to this amino acid).
