BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Explanation: Amino acids contain aliphatic R groups that are non-polar or hydrophobic. Glycine, alanine, valine, leucine, isoleucine, and proline are among the amino acids in this category.

Detailed explanation-2: -Aliphatic R groups are nonpolar and hydrophobic. Hydrophobicity increases with increasing number of C atoms in the hydrocarbon chain. Although these amino acids prefer to remain inside protein molecules, alanine and glycine are ambivalent, meaning that they can be inside or outside the protein molecule.

Detailed explanation-3: -Hydrophobic-aliphatic amino acids There are four amino acids in this class, as shown below. Their side chains consist of non-polar methyl-or methylene-groups. These amino acids are usually located on the interior of the protein as they are hydrophobic in nature.

Detailed explanation-4: -Phenylalanine, tyrosine and tryptophan all contain non-polar aromatic rings. Tyrosine and tryptophan are slightly less hydrophobic and slightly more reactive than phenylalanine because they contain an-OH and-NH group, respectively. Another amino acid that is actually hydrophobic is proline.
