Tutorial to help answer the question
Which amino acid has a hydrophobic side chain?
Tutorial
The hydrophobic amino acids|
There are 20 different amino acids found in proteins. The side chains (R-groups) differ in chemical properties. Some are polar, but uncharged. Some are polar and normally have a positive or negative charge in solution.
The eight amino acids shown below have distinctly hydrophobic side chains. Note that the side chains are composed almost entirely of C-C and C-H chemical bonds, being either entirely hydrocarbons, or mostly hydrocarbons with a single polar atom. |
