Video: A successful mission starts with nutrition

Centuries ago, large, wooden ships explored the seven seas. But often a ship that began its voyage with a crew of hundreds could return with tens. The silent killer? Scurvy, a disease that occurs when there's a lack of Vitamin ...

New research boosts antibiotic hope

Research carried out at the University of Exeter has advanced understanding of how some damaging bacteria behave and may pave the way for new and more targeted antibiotics.

New study sheds light on molecular machinery of nervous system

A University of Arkansas research team shed new light on the molecular properties that drive the nervous system. Their work was recently published in Biochemistry, one of the top journals in the field. Kelsey Sparks, an alumna ...

Researchers show fruit flies have latent bioluminescence

New research from Stephen C. Miller, PhD, associate professor of biochemistry and molecular pharmacology, shows that fruit flies are secretly harboring the biochemistry needed to glow in the dark—otherwise known as bioluminescence.

Computer-designed proteins recognize and bind small molecules

Computer-designed proteins that can recognize and interact with small biological molecules are now a reality. Scientists have succeeded in creating a protein molecule that can be programmed to unite with three different steroids.

Biochemists discover 'parking position' of fat-burning enzymes

Fat is a curse and a blessing at the same time. While we would rather not have any fat deposits on our body, especially in summer, accumulated fats in plants are desirable as they make them especially nutritious. Biochemists ...

Biochemistry

Biochemistry is the study of the chemical processes in living organisms. It deals with the structure and function of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules.

Although there are a vast number of different biomolecules many are complex and large molecules (called polymers) that are composed of similar repeating subunits (called monomers). Each class of polymeric biomolecule has a different set of subunit types. For example, a protein is a polymer whose subunits are selected from a set of 20 or more amino acids. Biochemistry studies the chemical properties of important biological molecules, like proteins, in particular the chemistry of enzyme-catalyzed reactions.

The biochemistry of cell metabolism and the endocrine system has been extensively described. Other areas of biochemistry include the genetic code (DNA, RNA), protein synthesis, cell membrane transport, and signal transduction.

Since all known life forms that are still alive today are descended from the same common ancestor, they have generally similar biochemistries. It is unknown whether alternative biochemistries are possible or practical.
