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.

Absorbed amino acids are typically used to create functional proteins, but may also be used to create energy. [3] They can also be converted into glucose. [4] This glucose can then be converted to triglycerides and stored in fat cells. [5] Proteins can be broken down by enzymes known as peptidases or can break down as a result of denaturation ...
Enzymes are not rigid, static structures; instead they have complex internal dynamic motions – that is, movements of parts of the enzyme's structure such as individual amino acid residues, groups of residues forming a protein loop or unit of secondary structure, or even an entire protein domain.
Pepsin / ˈ p ɛ p s ɪ n / is an endopeptidase that breaks down proteins into smaller peptides and amino acids.It is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.
Glycerol-3-phosphate dehydrogenase (GPDH) is an enzyme that catalyzes the reversible redox conversion of dihydroxyacetone phosphate (a.k.a. glycerone phosphate, outdated) to sn-glycerol 3-phosphate. [2] Glycerol-3-phosphate dehydrogenase serves as a major link between carbohydrate metabolism and lipid metabolism.
The glyoxylate shunt comprises two enzymes, malate synthase and isocitrate lyase, and is present in fungi, plants, and bacteria. Despite some reports of glyoxylate shunt enzymatic activities detected in animal tissues, genes encoding both enzymatic functions have only been found in nematodes, in which they exist as a single bi-functional enzyme.
Glucose + 2 ADP + 2 Pi → 2 ethanol + 2 CO 2 + 2 ATP + 2 H 2 O [38] Alcohol Dehydrogenase In yeast [ 39 ] and many bacteria , alcohol dehydrogenase plays an important part in fermentation: Pyruvate resulting from glycolysis is converted to acetaldehyde and carbon dioxide , and the acetaldehyde is then reduced to ethanol by an alcohol ...
Conversion of glucose to fructose by xylose isomerase was first patented in the 1960s. However, the process was not industrially practical as the enzymes were in solution, and recycling the enzyme was problematic. [7] An immobile xylose isomerase that was fixed on a solid surface was first developed in Japan by Takanashi. [7]
