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.

Deamination is the removal of an amino group from a molecule. [1] Enzymes that catalyse this reaction are called deaminases.. In the human body, deamination takes place primarily in the liver; however, it can also occur in the kidney.
Chemical denaturation [ edit ] In the less extensive technique of equilibrium unfolding , the fractions of folded and unfolded molecules (denoted as p N {\displaystyle p_{N}} and p U {\displaystyle p_{U}} , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the ...
Transamination is a chemical reaction that transfers an amino group to a ketoacid to form new amino acids.This pathway is responsible for the deamination of most amino acids. This is one of the major degradation pathways which convert essential amino acids to non-essential amino acids (amino acids that can be synthesized de novo by the organism).
An acid-base diagram for human plasma, showing the effects on the plasma pH when P CO 2 in mmHg or Standard Base Excess (SBE) occur in excess or are deficient in the plasma [23] Acid–base imbalance occurs when a significant insult causes the blood pH to shift out of the normal range (7.32 to 7.42 [ 16 ] ).
Biological processes are those processes that are necessary for an organism to live and that shape its capacities for interacting with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms. [1]
For example, Δ9-desaturase creates a double bond between the ninth and tenth carbon atom from the carboxyl end. Omega - indicating the double bond is created at a fixed position from the methyl end of a fatty acid chain. For instance, ω3 desaturase creates a double bond between the third and fourth carbon atom from the methyl end.
Hemoglobin A in humans can form hemichromes even under physiological conditions as a result of pH and temperature alterations, and the autoxidation of oxyhemoglobin. Hemichrome formation, followed by a band 3 clustering and the formation of Heinz bodies , can take place during the physiological clearance of damaged red blood cells. [ 4 ]
