Definitions

Cyclol

Cyclol , mainly because it eliminates the resonance stabilization of the peptide bond . This reaction was the basis of Dorothy Wrinch's cyclol model of proteins. The cyclol hypothesis is the first structural model of a folded , globular protein . The same studies appeared to show that the mo more

Enzyme kinetics

Enzyme kinetics from E. coli with its two substrates, dihydrofolate (right) and NADPH (left), bound in the active site. The protein is shown as a ribbon diagram , with alpha helices in red, beta sheets in yellow and loops in blue. Generated from 7DFR . Enzyme kinetics is the study of the chemic more

Exosome complex

Exosome complex below. The exosome complex (or PM/Scl complex, often just called the exosome) is a multi-protein complex , capable of degrading various types of RNA s. Exosome complexes can be found in both eukaryotic cells and archaea , while in bacteria a simpler complex called the degradosom more

Black pepper

Black pepper Black pepper (Piper nigrum) is a flowering vine in the family Piperaceae , cultivated for its fruit , which is usually dried and used as a spice and seasoning . The same fruit is also used to produce white pepper, red/pink pepper, and green pepper. Black pepper is native to South more

Oxidative phosphorylation

Oxidative phosphorylation in the mitochondrion is the site of oxidative phosphorylation in eukaryote s. The NADH and succinate generated in the citric acid cycle is oxidized, releasing energy to power the ATP synthase . Oxidative phosphorylation is a metabolic pathway that uses energy released b more
