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]
The perhydroxyl anion then attacks the activator, forming a peroxy acid: HO 2 − + RC(O)X → X − + RC(O)O 2 H The overall reaction of TAED ( 1 ) with 2 equivalents of hydrogen peroxide gives diacetylethylenediamine ( 2 ) and 2 equivalents of peracetic acid ( 3 ):
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. This white solid is commonly used as a bleach activator in laundry detergents and for paper pulp. It is produced by acetylation of ethylenediamine.
[3] [1] [4] [5] NV-5138 works by binding to and modulating sestrin2, a cellular sensor protein for the amino acid leucine, which is a natural activator of mammalian target of rapamycin complex 1 (mTORC1) signaling pathway.
Activator may refer to: Activator (genetics) , a DNA-binding protein that regulates one or more genes by increasing the rate of transcription Activator (phosphor) , a type of dopant used in phosphors and scintillators
N,N′-Dicyclohexylcarbodiimide (DCC or DCCD) [1] is an organic compound with the chemical formula (C 6 H 11 N) 2 C. It is a waxy white solid with a sweet odor. Its primary use is to couple amino acids during artificial peptide synthesis. The low melting point of this material allows it to be melted for easy handling.
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 the N-terminal region at amino acid position 55-61 the cdh1 protein contains a C-Box motif, which is required for the association with the APC/c complex. Especially the residue R56 seems to be important for the binding to APC/c in vitro and Cdh1 function in vivo. [9] [10] Cdh1 contains multiple phosphorylation sites for the kinase cdc28 ...
