Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and ...

New research by Penn State researchers reveals how several molecular roadblocks slow the breakdown of cellulose for biofuels. Here, Daguan Nong, assistant research professor of biomedical engineering, ...

Jason Boock and Jason Berberich, both professors of Chemical, Paper, and Biomedical Engineering at Miami University, are researching methods to produce an enzyme that has large potential to change how ...

Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

Nearly two centuries ago, scientists discovered bilirubin, a yellow pigment produced by the breakdown of red blood cells that turns the skin and whites of the eyes yellow if it accumulates in the body ...

Chemical digestion occurs when the body uses enzymes to break down certain molecules, such as carbohydrates. This process allows the bloodstream to absorb smaller molecules to transport around the ...

For much of nutrition science history, trace minerals were discussed almost exclusively in the context of deficiency diseases ...

Tracking individual enzymes during the breakdown of cellulose for biofuel production has revealed how several roadblocks slow this process when using plant material that might otherwise go to waste.
