Answer:
Here's what I get
Explanation:
Most of the common amino acids have the general formula RCH(NH₂)COOH.
We call the R groups the side-chains.
They account for the properties of the different amino acids, and we classify the amino acids according to the nature of the side chains.
1. Leucine
Leucine contains a four-carbon sidechain — an isobutyl group.
Alkyl groups are nonpolar and hydrophobic, so leucine is a hydrophobic amino acid.
2. Lysine
Lysine contains four carbon atoms and an NH₂ group.
Amino groups are basic, so lysine is a basic amino acid.
