Sentences with phrase «more reactive oxygen»

So, not only does the human body have difficulty metabolizing them, but these F&O's tend to produce more Reactive Oxygen Species (ROS / Free Radicals)

Under the hypoxic conditions, the body might produce more reactive oxygen species (ROS), harmful compounds that can damage DNA.

The damaged mitochondria become increasingly dysfunctional, producing even more reactive oxygen species and creating an undesirable cycle.

Not exact matches

«There was a concept that reactive oxygen species are bad,» he says, «but they can do more than harm cells.»

They found that soluble iron in the earliest oceans quickly combined with oxygen to form rust — forming reactive oxygen molecules, which damage biological tissue and make the cyananobacteria grow more slowly and produce less oxygen.

More research produced the answer: Vitamin C induced what is known as a Fenton reaction, causing iron to react with other molecules to create reactive oxygen species that kill the TB bacteria.

Among the most interesting ones identified were those associated with 1) the large category of transport, and the more specific categories of carbohydrate transport and cation: amino acid symport; 2) several related to calcium, including calcium ion binding, calmodulin binding, and voltage gated calcium channel activity; 3) DNA damage response and signal transduction; 4) response to oxidative stress; and 5) oxygen and reactive oxygen species metabolism.

The finding suggests that microbes with the ability to produce oxygen were prolific at least locally around 3.46 billion years ago, releasing large quantities of this reactive molecular gas into the oceans and eventually the atmosphere by the end of this period (more).

So while it's true that organisms living deep in the Earth are not exposed to the high - energy radiation found when you travel between planets or more hypothetically between stars, the systems that cells have evolved to repair damage done by reactive oxygen species will be useful whether they arise from rocks or from cosmic rays.

A child's heart is more sensitive to injury caused by interrupting blood flow during surgery, and excess reactive oxygen species are a key source of this damage.

«Past studies have shown that having low antioxidant levels and increased reactive oxygen species — chemical products that bind to body cells and cause damage — is related to more severe PAD,» said Matthew Muller, postdoctoral fellow in Larry Sinoway's lab at Penn State College of Medicine, and lead author of the study.

More than one hundred vitamin B6 - dependent enzymes have been identified, mostly involved in amino acid metabolism: for oxygen transport via hemoglobin synthesis; in blood sugar regulation via conversion of stored carbohydrate to energy; in the development of the myelin sheath surrounding nerve cells; in the conversion of alphalinoleic acid to the essential long - chain fatty acid DHA; 28 and in the synthesis of neurotransmitters, phospholipids and sphingolipids, the vitamin niacin from tryptophan, and other vital metabolites.5 In addition to its role in enzyme reactions, B6 appears to moderate the action of some steroid hormones such as the glucocorticoid hormones, which in turn influence the metabolism of protein, carbohydrate and lipids.5, 9 B6 also is a potent antioxidant, rivaling carotenoids and vitamin E in its ability to quench reactive oxidants in the body.29

As a general rule, the shorter the carbon chain, the more efficiently the MCT will be turned into ketones, which are an excellent source of energy for your body — far preferable to glucose, as ketones produce far less reactive oxygen species (ROS) when they are metabolized to produce ATP.

When your body is able to burn fat for fuel, your liver creates water - soluble fats called ketones that burn far more efficiently than carbs, thereby creating fewer reactive oxygen species (ROS) and secondary free radicals.
