The hydroxyl radical, Lewis structure shown, contains one unpaired electron. Lewis dot structure of a Hydroxide ion compared to a hydroxyl radical. In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron.
The hydroxyl radical can damage virtually all types of macromolecules: carbohydrates, nucleic acids , lipids (lipid peroxidation) and amino acids (e.g. conversion of Phe to m-Tyrosine and o-Tyrosine). The hydroxyl radical has a very short in vivo half-life of approximately 10 −9 seconds and a high reactivity. [5]
This new house was partly an elected body: the mid-level local governments (counties) and some corporative, cultural and scientific associations (such as, e.g., the universities or the chamber of commerce) got the right to co-opt deputies from their own members. From 1945 on, the Hungarian Parliament is a unicameral legislative body. Upper House

Specific examples include stroke and heart attack. [ citation needed ] In general, the harmful effects of reactive oxygen species on the cell are the damage of DNA or RNA, oxidation of polyunsaturated fatty acids in lipids ( lipid peroxidation ), oxidation of amino acids in proteins, and oxidative deactivation of specific enzymes by oxidation ...
The radical-pair, however, is not simply two radicals. This is because radical-pairs (specifically singlets) are quantum entangled , even as separate molecules. [ 1 ] More fundamental to the radical-pair mechanism, however, is the fact that radical-pair electrons both have spin, short for spin angular momentum , which gives each separate ...
Second law: The acceleration of an object of constant mass is proportional to the net force acting upon it. Third law: Whenever one body exerts a force upon a second body, the second body exerts an equal and opposite force upon the first body. Nielsen's law: A high-end user's internet connection speed grows by 50% per year.
