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 cellular process that builds macromolecules by linking monomers is ?
Cellular process that builds macromolecules by linking monomers through covalent bonds is called Dehydration synthesis because water molecules are released as byproducts.
This reaction is also considered to be a condensation reaction because two molecules are condensed into one larger molecule with loss of smaller molecule(water).
key points
- In dehydration synthesis combination occurs through two ways.Either hydrogen of one monomer combine with hydroxyl group of another monomer (which releases a molecule of water) or two hydrogen from one monomer combine with one oxygen from other monomer releasing a molecule of water
- Monomers that are joined by this reaction share electron and form covalent bonds with each other.
- As more and more monomers are joined ,this chain begins to form a polymer.
- Examples-Complex carbohydrate,nucleic acids, protein are all macromolecules that are formed by dehydration synthesis.
- An acid catalyst can be used during a dehydration synthesis reaction.
