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.

The hydrophobicity or hydrophilicity of the amino acids in a protein is quantitatively analysed using a hydrophilicity plot. It is used to describe or pinpoint a protein's potential structure or domains.
-The plot's x-axis represents the amino acid sequence of a protein, and the y-axis represents the degree of hydrophobicity and hydrophilicity.
- The degree of interaction between particular amino acids and polar solvents like water can be determined using a variety of techniques. For instance, the Hopp-Woods scale assesses hydrophilic residues while the Kyte-Doolittle scale identifies hydrophobic amino acids.
Hopp-Woods scale - The Hopp-Woods hydrophilicity scale of amino acids is a technique for ordering amino acids in a protein according to their water solubility in order to look for surface locations on proteins, particularly those locations that tend to form strong interactions with other macromolecules like proteins, DNA, and RNA.
