<span>Cellular life forms have been divided into a three domain system. This system divides cellular life forms in archaea, bacteria and eukaryote domains. While studying the r RNAs of the organisms from these 3 domains, scientists came to the conclusion that all the organisms have a common ancestor due to the many similarities found. This common ancestor is not the first living organism in the Earth. This common ancestor is referred to as Last Universal Common Ancestor.</span>

What type of amino acids would you expect to find at the core of a water-soluble globular (solid-spherical) protein
PIT_PIT [208]

Hydrophobic amino acids are buried at the core of a water-soluble globular protein.

<h3>What makes globular proteins water soluble?</h3>

Numerous hundreds to thousands of amino acids are used to make proteins. The arrangement of amino acids within a protein molecule determines its ultimate form. A protein molecule is classified into two classes—fibrous proteins and globular proteins—based on its final shape.

The structure of globular proteins resembles a ball or a globe. A globular structure is created by the folding of different amino acid chains. The two most significant globular proteins present in the human body are hemoglobin and myoglobin. The hydrophobic side chains of the amino acids are hidden inside the cores of the domains whereas the hydrophilic side chains are located on the surface of the molecule thanks to the arrangement of the amino acids.

The hydrophobic amino acids can be buried in the center of globular proteins due to interactions between the hydrophobic groups in their side chains. This is the fundamental property of globular proteins that makes them water soluble.

Examples of hydrophobic amino acids are phenylalanine,  alanine, valine, etc.
