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.

Answer:
Endocardium
Explanation:
The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.
The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.
One of the main differences between eukaryotic cells and prokaryotic cells is the presence of a nucleus and other membrane-bound organelles. ... Because of this, scientists believe that both of these organelles originated through endosymbiosis when one small cell began to live inside a larger one.
