No, because “free” nitrogen is not combined with other kinds of atoms.
Most organisms can use nitrogen only once it has been "fixed" or combined with other elements to form nitrogen-containing compounds.
Feral rock pigeons were screened for neutralizing antibodies to West Nile virus during late winter/spring and summer of 2002 and 2003. Additionally, virus isolation from serum was attempted from 269 birds collected during peak transmission
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.

Consuming enough protein is important because the broken down protein is used for energy. Consuming relatively high or excess protein is still safe and healthy but too much of it can be associated with different complications in the body.
Some of the problems associated with the excess protein are: (1) weight gain, (2) reduced liver and brain function, and (3) high cholesterol.
