In most human disease, oxidative stress is merely a symptom.

People exposed to increased oxidative stress may have elevated antioxidant requirements.

So the link between oxidative stress and disease should not be overemphasized.

But it is not part of metabolism itself.

In thermodynamic terms, metabolism maintains order by creating disorder.

New York s metabolism filled me with its energy and its toxins.

They can also be damaged by the products of normal metabolism.

Many proteins are enzymes that catalyze the chemical reactions in metabolism.

The first pathways of enzyme based metabolism may have been parts of purine nucleotide metabolism, while previous metabolic pathways were a part of the ancient RNA world.

It is found in urine as a normal product of protein metabolism.

They ask if it should have reproduction in it, or metabolism, or evolution.

The relationship between epilepsy and glucose metabolism was established more than 85 years ago.

Within the OMZ, oxygen saturation is too low to support aerobic metabolism in most higher organisms.

Bacteria of the genus Propionibacterium produce propionic acid as the end product of their anaerobic metabolism.

Aging is a side effect of being alive in the first place, which is to say, metabolism.

The fly is also being used to study mechanisms underlying aging and oxidative stress, immunity, diabetes, and cancer, as well as drug abuse.

It also is unclear whether oxidative stress is a primary cause or a secondary phenomenon of chronic diseases, as well as of the aging process.

Extrinsic control involves a cell in a multicellular organism changing its metabolism in response to signals from other cells.

The biologists believe that a slow metabolism, which results in slower development, plays an important role in the shark's longevity.

For example, Narzan has anti inflammatory and immunomodulatory effects, and repairs the function of the gastrointestinal tract and the metabolism.

A vertical takeoff aircraft, like the hummingbird, has a very high metabolism, which means it requires a lot of energy.

It was initially assumed that the alkaloids are the final products of nitrogen metabolism in plants, as urea in mammals.

One of the most prolific of these modern biochemists was Hans Krebs who made huge contributions to the study of metabolism.

So basically, metabolism, which is defined as basically everything that keeps us alive from one day to the next, has side effects.

I'm going to use this word damage to denote these intermediate things that are caused by metabolism and that eventually cause pathology.

Which is the driving parameter which gives me a perceived temperature? And these parameters, these climatic parameters are related to the human metabolism.

Genes can be damaged by environmental factors, such as radiation or chemicals. They can also be damaged by the products of normal metabolism.

The most important processes for converting the energy trapped in chemical substances into energy useful to sustain life are metabolism and cellular respiration.

The main role of antioxidants is to prevent oxidative damage to cellular components, so it has been proposed that dietary antioxidants decrease such damage and with it the risk of disease.

Alright? So not only do we have this system that has a body, it has a metabolism, it can use energy, it moves around.

When the active component was purified from the liquid, it turned out to be a byproduct of tryptophan metabolism known as indole 3 lactic acid.

Enzymes carry out most of the reactions involved in metabolism, as well as manipulating DNA in processes such as DNA replication, DNA repair, and transcription.

The response is fuelled by stress hormones that flow through the body, altering every organ and biochemical function, with wide ranging effects on metabolism, growth, and reproduction.

Water bears several vital functions in a man's organism. It serves as a transport means for nutrients, regulates body temperature, and plays an important part in metabolism.

Some CNVs are also associated with genes involved in immune response and detoxification related metabolism (some of the human body s reactions to the environment that we live in).

Life also has a metabolism. Now this is a process by which life can convert resources from the environment into building blocks so it can maintain and build itself.

Okay? Oil droplet forms through self assembly, has a chemical metabolism inside so it can use energy, and it uses that energy to move itself around in its environment.

Depression thus leads to changes in the rest of the body, owing to long term chemical imbalances in the systems that control the heart, the immune system, and metabolism.

Overall, these studies give a good view of the structure and function of simple metabolic pathways, but are inadequate when applied to more complex systems such as the metabolism of a complete cell.

The proteins that are produced, their quantities, and their characteristics collectively form the proteome, and their activities, in combination or in response to signals from within the body or external to it, form our metabolism.

However, because neither species can survive long in the other's ecological niche, and because they have different morphology, metabolism, social and feeding behaviors, and other phenotypic characteristics, the two bears are generally classified as separate species.

Many chemical mediators are involved, including cortisol and adrenalin from the adrenal glands, other hormones and neurotransmitters (such as serotonin and noradrenalin), and responses from the autonomic and immune systems. Depression thus leads to changes in the rest of the body, owing to long term chemical imbalances in the systems that control the heart, the immune system, and metabolism.
