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. Proteins can denature in environmental conditions the protein is not made for. [6]
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.

The agr (accessory gene regulator) locus [a] is one of the key sites of positive regulation for many of the S. aureus genes, including TSST-1. [9] Additionally, alterations in the expression of the genes ssrB and srrAB affect the transcription of TSST-1. [7] Further, high levels of glucose inhibit transcription, since glucose acts as a ...
Whereas free glucose can easily diffuse in and out of the cell, the phosphorylated form (glucose-6-phosphate) is locked in the cell, a mechanism by which intracellular glucose levels are controlled by cells. The final step in gluconeogenesis, the formation of glucose, occurs in the lumen of the endoplasmic reticulum, where glucose-6-phosphate ...
The HD gene [8] is found in all human genomes. In the event that a slippage event occurs there can be a large expansion in the tandem repeats of the HD gene. [8] An individual who is not affected by Huntington's disease will have 6-35 tandem repeats at the HD locus. However, an affected individual will have 36- 121 repeats present. [7]
In humans this protein is encoded by the SORD gene. [1] Sorbitol dehydrogenase is an enzyme in carbohydrate metabolism converting sorbitol, the sugar alcohol form of glucose, into fructose. [2] Together with aldose reductase, it provides a way for the body to produce fructose from glucose without using ATP.
Furthermore, one can assess whether the folding proceeds according to a two-state unfolding as described above. This can be done with differential scanning calorimetry by comparing the calorimetric enthalpy of denaturation i.e. the area under the peak, A peak {\displaystyle A_{\text{peak}}} to the van 't Hoff enthalpy described as follows:
The schematic diagram indicates the roles of insufficient DNA repair in aging and cancer, and the role of apoptosis in cancer prevention. An excess of naturally occurring DNA damage, due to inherited deficiencies in particular DNA repair enzymes, can cause premature aging or increased risk for cancer (see DNA repair-deficiency disorder).
