Tyrosine and tryptophan are less hydrophobic than phenylalanine because . Tyrosine and tryptophan are less hydrophobic than phenylalanine because . Phenylalanine has an indole group Phenylalanine is a phenol Tyrosine and tryptophan have smaller R groups Phenylalanine has no polar group in the side chain

Phenylalanine has no polar group in the side chain

Explanation:

Unlike phenylanine with a nonpolar methyl benzyl group in its side chain, tryptothan and tyrosine on the other hand possesses a polar indole ring and hydroxyl group in their side chain respectively, which helps them form hydrogen bonds with water molecules.

Thus, both are less hydrophobic (water-hating) than phenylanine.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.
