Some organisms thrive at pH 2; other organisms thrive at 65°C. Yet mammals cannot tolerate either environment in their tissues. Explain why in terms of the structure and function of proteins under different environmental conditions
Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.

Protein structures are produced by the condensing of amino acids into peptide bonds. The arrangement of amino acids in a protein is referred to as its fundamental structure. The secondary structure is governed by the dihedral angles of the peptide bonds, and the tertiary structure is by the packing of protein chains in spaces. The interaction of folded polypeptide molecules with complex functional protein molecules results in a quaternary structure. The structure of the protein is affected by a variety of external factors which mainly involve pH and temperature.
