Sentences with phrase «reactive compounds known»

Ionizing radiation damages cells by producing very reactive compounds known as free radicals.

One possibility for how that happens, says Hekimi, is that slow cellular metabolism delays the normal buildup of metabolic byproducts, such as reactive compounds known as free radicals, that are toxic to cells.

Not exact matches

Air monitoring by researchers in 2000 found levels of volatile organic compounds — highly reactive ozone precursors such as benzene, known as VOCs — were 10 to 100 times higher than what had previously been estimated.

For example, early global chemical modelling results argued that global tropospheric ozone, a greenhouse gas, was controlled by emissions of the highly reactive gases nitrogen oxides (NOx), carbon monoxide (CO) and non-methane hydrocarbons (NMHC, also known as volatile organic compounds, VOC).
