oxidatiivisia

Oxidatiivisia is a Finnish term that translates to "oxidative" in English. It refers to processes involving oxidation, which is a chemical reaction that results in the loss of electrons or an increase in oxidation state of an atom, molecule, or ion. In biological contexts, oxidative processes are fundamental to cellular respiration, where glucose is broken down in the presence of oxygen to produce energy (ATP). These reactions involve the transfer of electrons through a series of protein complexes.

Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species (ROS) and the body's ability to detoxify them or repair the resulting damage. ROS are highly reactive molecules that can damage cellular components like DNA, proteins, and lipids. While ROS play a role in normal cellular signaling and immune responses, excessive levels can lead to various diseases, including cardiovascular disease, cancer, neurodegenerative disorders, and aging.

Antioxidants are compounds that can inhibit oxidation. They work by neutralizing ROS, thereby protecting cells from oxidative damage. The body produces its own antioxidants, such as superoxide dismutase and glutathione, and also obtains them from dietary sources like vitamins C and E, and various phytochemicals found in fruits and vegetables. Maintaining a healthy balance between oxidative processes and antioxidant defenses is crucial for overall health and well-being.
