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.

Soil pH and texture are both factors that can moderate denitrification, with higher pH levels driving the reaction more to completion. [22] Nutrient composition, particularly the ratio of carbon to nitrogen, is a strong contributor to complete denitrification, [ 23 ] with a 2:1 ratio of C:N being able to facilitate full nitrate reduction ...
The enzyme alkaline phosphatase (ALP, alkaline phenyl phosphatase) is a phosphatase with the physiological role of dephosphorylating compounds. The enzyme is found across a multitude of organisms, prokaryotes and eukaryotes alike, with the same general function, but in different structural forms suitable to the environment they function in. Alkaline phosphatase is found in the periplasmic ...
The higher sulfuric acid content of rain also may not release as much Al 3+ from soils as does nitric acid, in part due to the retention (adsorption) of SO 4 2-by soils. This process releases OH − into soil solution and buffers the pH decrease caused by the added H + from both acids. The forest floor organic soil horizons (layers) that are ...
Protein precipitation is widely used in downstream processing of biological products in order to concentrate proteins and purify them from various contaminants. For example, in the biotechnology industry protein precipitation is used to eliminate contaminants commonly contained in blood. [1]
However, drying surface soil and rising temperatures as spring progresses increases the probability of ammonia volatilization. [1] Ideally, a manager should attempt to apply nitrogen immediately before a moderate rain event (0.1 inch), allowing urea to dissolve and move into the soil. However, this is not always possible.
RuBisCO is important biologically because it catalyzes the primary chemical reaction by which inorganic carbon enters the biosphere.While many autotrophic bacteria and archaea fix carbon via the reductive acetyl CoA pathway, the 3-hydroxypropionate cycle, or the reverse Krebs cycle, these pathways are relatively small contributors to global carbon fixation compared to that catalyzed by RuBisCO.
Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life ...
