The primary structure of a protein is an alpha helix or a pleated sheet. the amino acid sequence of the polypeptide chain. composed of two or more polypeptide chains. maintained by hydrogen bonds.
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.
There are four essential biomolecules present in the living world:
- Carbohydrates: sugars
- Proteins: made up of amino acids
- Fats: made up of fatty acids
- Nucleic acids: the DNA and the RNA
All these biomolecules have distinct structures, functions and bonds between their monomer units.
For example, the carbohydrates are made up of glycosidic bonds between the monomer units and are source of energy in the body while the nucleic acids have phosphodiester and hydrogen bonds and are the genetic material of the body.
