Question
Functional group in al amino Found in some nonpolar? hydrophilic? amino acids? acids? -OH -CH2 Now -COOH -NH2 -SH PO. Twenty amino acids are commonly used in the synthesis of proteins. The chemical properties of their side chains (R groups) differ. What properties doeseach of the following R-groups have? Note that the structures are drawn different ways, some show all the bonds, cs, and Hs, some do not. Hydrophobic or Basic, acidic, or Polar or nonpolar? R group hydrophilic? neutral? Neon Polar hydro Problc CH2 H-C-OHExplanation / Answer
