In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

In biochemistry, a zymogen (/ ˈ z aɪ m ə dʒ ən,-m oʊ-/ [1] [2]), also called a proenzyme (/ ˌ p r oʊ ˈ ɛ n z aɪ m / [3] [4]), is an inactive precursor of an enzyme.A zymogen requires a biochemical change (such as a hydrolysis reaction revealing the active site, or changing the configuration to reveal the active site) for it to become an active enzyme.
Unrelated enzymes that have the same enzymatic activity have been called non-homologous isofunctional enzymes. [23] Horizontal gene transfer may spread these genes to unrelated species, especially bacteria where they can replace endogenous genes of the same function, leading to hon-homologous gene displacement.
Denitrification can lead to a condition called isotopic fractionation in the soil environment. The two stable isotopes of nitrogen, 14 N and 15 N are both found in the sediment profiles. The lighter isotope of nitrogen, 14 N, is preferred during denitrification, leaving the heavier nitrogen isotope, 15 N, in the residual matter.
Enzymes are critical to our survival, but human enzymes have different properties than enzymes found in the things we eat, including all plant-based and animal foods.
Phosphorylation occurs when a PO 3 (phosphoryl) group is added to a protein. [3] This chemical modification is the most extensively studied and is reversible. The result of those studies has shown that phosphorylation acts as a regulator for proteins in two ways: the addition or removal of phosphoryl group can impact enzyme kinetics by turning on or off the enzymatic function via ...
The 'Old Farmer's Almanac' Christmas weather predictions are here, and it looks like it will be a mild holiday. Here's what to expect on December 25 in 2024.
Meanwhile, United Airlines continues to see premium cabin revenue outperform the rest of its travel tiers during the third quarter and record levels of spending among co-branded credit cardholders.
