- Dismutase - Superoxide dismutases (SOD, EC 188.8.131.52) are a class of enzymes that catalyze the dismutation of superoxide into oxygen and hydrogen peroxide. As such, they are an important antioxidant defense in nearly all cells exposed to oxygen. One of the exceedingly rare exceptions is Lactobacillus plantarum and related lactobacilli, which use a different mechanism.
- Chelation - Chelation (pronounced /kiːˈleɪʃən/) is the formation or presence of two or more separate bindings between a polydentate (multiple bonded) ligand and a single central atom. Usually these ligands are organic compounds, and are called chelants, chelators, chelating agents, or sequestering agents
- Sequester - to remove or withdraw into solitude or retirement; seclude
- Cytochrome P450 - The cytochrome P450 family (officially abbreviated as CYP) is a large and diverse group of enzymes. The function of most CYP enzymes is to catalyze the oxidation of organic substances. The substrates of CYP enzymes include metabolic intermediates such as lipids, steroidal hormones as well as xenobiotic substances such as drugs.
- Suberin - Suberin is a waxy substance found in higher plants. Suberin is a main constituent of cork, and is named after the Cork Oak, Quercus suber.
- Lignin - Lignin or lignen is a complex chemical compound most commonly derived from wood, and an integral part of the secondary cell walls of plants and some algae. The term was introduced in 1819 by de Candolle and is derived from the Latin word lignum, meaning wood. It is one of the most abundant organic polymers on Earth, exceeded only by cellulose, employing 30% of non-fossil organic carbon and constituting from a quarter to a third of the dry mass of wood. As a biopolymer, lignin is unusual because of its heterogeneity and lack of a defined primary structure. Its most commonly noted function is the support through strengthening of wood (xylem cells) in trees.
- Autofluorescence - Autofluorescence is the fluorescence of other substances than the fluorophore of interest. It increases the background signal.
- Prolyl - The univalent acid radical, C4H8NCO, of proline.
- Peat - Peat is an accumulation of partially decayed vegetation matter. Peat forms in wetland bogs, moors, muskegs, pocosins, mires, and peat swamp forests. Peat is harvested as an important source of fuel in certain parts of the world. By volume there are about 4 trillion m³ of peat in the world covering a total of around 2% of global land mass (about 3 million km²), containing about 8 billion terajoules of energy.
- Wet-ashing - A method for the decomposition of an organic material, such as resins or fibers, into an ash by treatment with nitric or sulfuric acids.
