«Our modifications allow this material to entrap glucose oxidase molecules, which effectively amplifies the signal,» Prasad said.

Not exact matches

When a target molecule such as glucose binds to its recognition group (in this case an enzyme called glucose oxidase), the resulting pair carries a net electric charge.

Galactose oxidase achieves this configuration by forcing the copper atom to bind to five compounds — four amino acids and one water molecule — in a pyramid - shaped arrangement that keeps it a bit unsatisfied, looking for more action.

When a drop of blood is added to the device, the glucose oxidase splits glucose molecules, swiping electrons in the process.

The study, Lysyl oxidase and adipose tissue dysfunction, found that this molecule is more prevalent in fat tissue of obese people and that it was increased by inflammation and oxygen deprivation.

The research published in the journal Metabolism, examined a molecule called Lysyl oxidase (LOX) which regulates scarring by making tissue stiffer.

Unfortunately, researchers haven't had much luck in tweaking this approach to detect other molecules, in part because there aren't many enzymes like glucose oxidase that are tailored to work on a specific compound.

In studies in the laboratory, researchers from Baylor and the University of Geneva found that sentinel cells in the multi-cellular social amoeba slug use a form of toll - like receptor (that recognizes molecules from the microbes), as well as an enzyme called NADPH oxidase, in order to form these extracellular nets.

Certain particle compounds may directly generate ROS in vivo because of their surface chemistry (eg, metals, organic compounds, and semiquinones) or after bioactivation by cytochrome P450 systems (eg, polycyclic aromatic hydrocarbon conversion to quinones).6, 290 a, 290 b A particle surface or anions present on otherwise more inert particles may disrupt iron homeostasis in the lung and thereby also generate ROS via Fenton reactions.291 Other PM constituents may do so indirectly by the upregulation of endogenous cellular sources (eg, nicotinamide adenine dinucleotide phosphate [NADPH]-RRB- oxidase) 292,293 or by perturbing organelle function (eg, mitochondria) by taken - up PM components.261 Particle stimulation of irritant and afferent ANS fibers may also play a role in local and systemic oxidative stress formation.294 Given the rich antioxidant defenses in the lung fluid, secondarily generated oxidization products of endogenous molecules (eg, oxidized phospholipids, proteins) or a reduction in endogenous antioxidants per se may be responsible at least in part for the state of oxidative stress in the lungs (along with instigating the subsequent cellular responses) rather than ROS derived directly from PM and its constituents.

In your mitochondria, there's also a specific molecule called cytochrome c oxidase, which is involved in the energy production within the mitochondria.
