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 pineapple is an example of a CAM plant. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night. In a plant using full CAM, the stomata in the leaves ...
Deamination. 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. In situations of excess protein intake, deamination is used to break down amino acids for energy.
Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding. Proteins are made from amino acids. In humans, some amino acids can be synthesized using already existing intermediates.
Partial denaturation actually improves hemocyanin's PPO activity by providing greater access to the active site. [46] Aureusidin synthase is homologous to plant polyphenol oxidase, but contains certain significant modifications. [citation needed] Aurone synthase [47] catalyzes the formation of aurones.
Acid-growth hypothesis. The acid-growth hypothesis is a theory that explains the expansion dynamics of cells and organs in plants. It was originally proposed by Achim Hager and Robert Cleland in 1971. [1][2] They hypothesized that the naturally occurring plant hormone, auxin (indole-3-acetic acid, IAA), induces H + proton extrusion into the ...
DNA unwinding at the DUE, allowing for formation of replication fork for DNA replication to occur. A DNA unwinding element (DUE or DNAUE) is the initiation site for the opening of the double helix structure of the DNA at the origin of replication for DNA synthesis. [1] It is A-T rich and denatures easily due to its low helical stability, [2 ...
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. This is in accordance with Justus von ...
