Why are enzymes considered organic? Catalysts: Catalysts are key to many reactions both in chemistry and in biology. They speed up or lower the activation energy needed for a reaction to occur, without being used up in the process. Answer and Explanation: ...
Enzymes: Enzymes are proteins that possess catalytic activity. They are capable of accelerating chemical reactions that are needed for life. Mutations in the coding sequence of enzyme genes are often associated with disease. Answer and Explanation:1 ...
ENZyme KINetics is the study of the chemical reactions that are catalysed by enzymes. In enzyme kinetics the reaction rate is measured and the effects of varying the conditions of the reaction investigated. Studying an enzyme kinetics in this way can reveal the catalytic mechanism of this enzyme,...
Cholesterol is an essential component of cellular membranes regulating the structural integrity and fluidity of biological bilayers and cellular processes such as signal transduction and membrane trafficking. However, tools to investigate the role and dy
The protein and RNA composition of supermeres differs from small extracellular vesicles and exomeres. Supermeres are highly enriched with cargo involved in multiple cancers (glycolytic enzymes, TGFBI, miR-1246, MET, GPC1 and AGO2), Alzheimer’s disease (APP) and cardiovascular disease (ACE2, ...

The interest in the understanding of these reactions is thus unquestionable, and especially the role of enzymes in accelerating a chemical step that otherwise would not take place. Indeed, inositol phosphatase has the greatest catalytic effect ever found, accelerating a reaction by 21 orders of ...
5d). This behaviour suggests that PRC1 condensates serve as reaction crucibles, a finding that echoes those in a recent study where H2B ubiquitination enzymes were found to form a “reaction-chamber condensate,” possibly in a similar manner to PRC147. Consistent with this picture, even after ...
Given that rivaroxaban, apixaban and edoxaban are metabolised by liver enzymes, hepatic impairment can considerably affect the disposition of these anticoagulants [110]. Moderately impaired liver function is associated with 2.27-fold increase in rivaroxaban exposure, which is paralleled by an increase in...
