NOBS is the main bleach activator used in the U.S.A. and Japan. [4] Compared to TAED, which is the predominant bleach activator used in Europe, NOBS is efficient at much lower temperatures. At 20 °C NOBS is 100 times more soluble than TAED in water. [5]
Tetraacetylethylenediamine, commonly abbreviated as TAED, is an organic compound with the formula (CH 3 C(O)) 2 NCH 2 CH 2 N(C(O)CH 3) 2. It is a white solid commonly used as a bleach activator in laundry detergents and in the production of paper pulp. TAED is synthesized through the acetylation of ethylenediamine.
Alteplase, sold under the brand name Activase among others, is a biosynthetic form of human tissue-type plasminogen activator (t-PA). It is a thrombolytic medication used to treat acute ischemic stroke, acute ST-elevation myocardial infarction (a type of heart attack), pulmonary embolism associated with low blood pressure, and blocked central venous catheter.

Sirtuin-activating compounds (STAC) are chemical compounds having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. They are caloric restriction mimetic compounds that may be helpful in treating various aging -related diseases.
In phosphors and scintillators, the activator is the element added as dopant to the crystal of the material to create desired type of nonhomogeneities. In luminescence , only a small fraction of atoms, called emission centers or luminescence centers , emit light.
Carbamoyl phosphate synthetase (glutamine-hydrolysing) (EC 6.3.5.5) is an enzyme that catalyzes the reactions that produce carbamoyl phosphate in the cytosol (as opposed to type I, which functions in the mitochondria).
By inhibiting PAI-1, it increases activity of the enzymes tissue plasminogen activator and urokinase, which are involved in the blood clotting cascade. It has been researched for conditions such as hepatic steatosis and diabetic nephropathy, and while it has not been developed for medical use, it is widely used in scientific research. [1] [2 ...
D-glucose 6-phosphate + NADP + + H 2 O ⇌ 6-phospho-D-glucono-1,5-lactone + NADPH + H + This enzyme participates in the pentose phosphate pathway (see image), a metabolic pathway that supplies reducing energy to cells (such as erythrocytes ) by maintaining the level of the reduced form of the co-enzyme nicotinamide adenine dinucleotide ...
