Origin of Biochemistry



The Historical Background of Biochemistry



Biochemistry is the study of chemical processes and compounds that occur within living organisms. Its history can be traced back to ancient times when observations of biological phenomena began. However, it emerged as a distinct scientific discipline in the 19th century. Early studies focused on the chemical composition of biological substances like proteins, carbohydrates, and fats.

In the late 19th and early 20th centuries, notable advancements were made, such as the discovery of enzymes and their role in catalyzing biochemical reactions.



























The understanding of metabolism and energy transfer also progressed during this time.

The mid-20th century saw a significant surge in biochemistry with the elucidation of the structure of DNA and the central dogma of molecular biology. Techniques like X-ray crystallography and advancements in spectroscopy greatly contributed to understanding molecular structures.

Over subsequent decades, research in biochemistry expanded to encompass topics such as genetics, cell biology, molecular biology, and biotechnology. Advances in technology, such as recombinant DNA and sequencing, revolutionized the field, allowing for deeper insights into the molecular mechanisms of life processes. Today, biochemistry continues to evolve with breakthroughs in areas like genomics, proteomics, and systems biology.


Certainly! Let's delve deeper into the historical development of biochemistry.

Early Foundations (Ancient to 18th Century): Biochemistry traces its roots back to ancient civilizations where people observed and began to document aspects of life processes. The Greeks, for instance, recognized the importance of substances like blood and various organs in sustaining life.


























Alchemy, an ancient precursor to chemistry, also played a role in the understanding of substances and their transformations.

Emergence as a Distinct Discipline (Late 18th to 19th Century): The late 18th and early 19th centuries marked the emergence of chemistry as a scientific discipline. Antoine Lavoisier, known as the "Father of Modern Chemistry," conducted foundational work in chemical reactions and the conservation of mass. His work laid the groundwork for understanding chemical processes within biological systems.

Discovery of Organic Compounds and Proteins (Early to Mid-19th Century): During the 19th century, significant discoveries were made in organic chemistry. Friedrich Wöhler synthesized urea, previously thought to only originate from biological sources, challenging vitalism. This highlighted the connection between chemical processes in living organisms and those in non-living matter. In the mid-1800s, the discovery and understanding of proteins as essential biological molecules further contributed to the growth of biochemistry.

Enzymes and Biochemical Reactions (Late 19th to Early 20th Century): The late 19th and early 20th centuries saw the discovery of enzymes and their crucial role in biochemical reactions.

























Eduard Buchner's discovery of cell-free fermentation in 1897 demonstrated that biological processes could occur outside living organisms, paving the way for enzymology.

Central Dogma and Molecular Biology (Mid-20th Century): The mid-20th century brought about a revolution with the discovery of the structure of DNA by James Watson and Francis Crick in 1953. This discovery, along with the formulation of the central dogma of molecular biology, provided a foundational understanding of genetic information transfer and paved the way for modern biotechnology.

Technological Advancements and Modern Biochemistry (Late 20th Century to Present): Advances in technology, including X-ray crystallography, nuclear magnetic resonance (NMR), mass spectrometry, and various molecular biology techniques, propelled biochemistry into a new era. Techniques like PCR (Polymerase Chain Reaction), DNA sequencing, and recombinant DNA technology significantly advanced the understanding of genes, proteins, and molecular mechanisms within cells.

Integration with Other Fields (Late 20th Century to Present): Modern biochemistry has become an interdisciplinary field, integrating knowledge from genetics, cell biology, microbiology, and more.






















Genomics, proteomics, metabolomics, and systems biology are areas of active research, allowing for a comprehensive understanding of the molecular basis of life, diseases, and the development of new therapies.

Throughout its evolution, biochemistry has continuously adapted and expanded, deeply impacting our understanding of life at the molecular level and driving advancements in medicine, agriculture, and biotechnology.

Nanoparticles Made From Plant Viruses


A new form of agricultural pest control could one day take root—one that treats crop infestations deep under the ground in a targeted manner with less pesticide.

Engineers at the University of California San Diego have developed nanoparticles, fashioned from plant viruses, that can deliver


Pesticide inside the nanoparticles, rather than chemically binding it to the surface, this method preserves the original chemical structure of the pesticide.

“If we had used a traditional synthetic method where we link the pesticide molecules to the nanoparticles, we would have essentially created a new compound, which will need to go through a whole new registration and regulatory approval process,” said study first author Adam Caparco, a postdoctoral researcher in Steinmetz’s lab.

























“But since we’re just encapsulating the pesticide within the nanoparticles, we’re not changing the active ingredient, so we won’t need to get new approval for it. That could help expedite the translation of this technology to the market.”

Moreover, the tobacco mild green mosaic virus is already approved by the Environmental Protection Agency (EPA) for use as an herbicide to control an invasive plant called the tropical soda apple. This existing approval could further streamline the path from lab to market.

The researchers conducted experiments in the lab to demonstrate the efficacy of their pesticide-packed nanoparticles. The nanoparticles were watered through columns of soil and successfully transported the pesticides to depths of at least 10 centimeters.

The solutions were collected from the bottom of the soil columns and were found to contain the pesticide-packed nanoparticles.





























When the researchers treated nematodes with these solutions, they eliminated at least half of the population in a petri dish.

While the researchers have not yet tested the nanoparticles on nematodes lurking beneath the soil, they note that this study marks a significant step forward.

“Our technology enables pesticides meant to combat nematodes to be used in the soil,” said Caparco. “These pesticides alone cannot penetrate the soil. But with our nanoparticles, they now have soil mobility, can reach the root level, and potentially kill the nematodes.”

Future research will involve testing the nanoparticles on actual infested plants to assess their effectiveness in real-world agricultural scenarios. Steinmetz’s lab will perform these follow-up studies in collaboration with the U.S. Horticultural Research Laboratory. Her team has also established plans for an industry partnership aimed at advancing the nanoparticles into a commercial product.

Paper title: “Delivery of Nematicides Using TMGMV-Derived Spherical Nanoparticles.” Co-authors include Ivonne Gonzalez-Gamboa, Samuel S. Hays and Jonathan K. Pokorski, UC San Diego.
