Kojic acid is an organic compound with the formula HOCH 2 C 5 H 2 O 2 OH. It is a derivative of 4-pyrone that functions in nature as a chelation agent produced by several species of fungi, especially Aspergillus oryzae , which has the Japanese common name koji .
The human protein acid transporter (hPAT1) is 5585 base pairs long and codes for a protein 476 amino acids long. The transporter has nine transmembrane regions where the amino terminus faces the cytoplasm. The rat protein acid transporter (rPAT1) has been widely studied and an 85% amino acid sequence match was found between hPAT1 and rPAT1.
It is a spontaneous reaction and a type of post-translational modification of proteins meaning it alters their structure and biological activity. It is the covalent attachment between the carbonil group of a reducing sugar (mainly glucose and fructose) and the amino acid side chain of the protein. In this process the intervention of an enzyme ...
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 .
An electron transport chain (ETC [1]) is a series of protein complexes and other molecules which transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occurring simultaneously) and couples this electron transfer with the transfer of protons (H + ions) across a membrane.
Numerous exported proteins form disulfide bonds—covalent bonds that stabilize the protein structure in harsh extracellular environments. A classic example are the disulfide-linked heavy and light chain polypeptides of antibodies secreted by B-cells of the immune system. Another key event that takes place in the ER is N-linked glycosylation.
Intracellular transport is the movement of vesicles and substances within a cell. Intracellular transport is required for maintaining homeostasis within the cell by responding to physiological signals. [1] Proteins synthesized in the cytosol are distributed to their respective organelles, according to their specific amino acid’s sorting ...
A membrane transport protein is a membrane protein involved in the movement of ions, small molecules, and macromolecules, such as another protein, across a biological membrane. Transport proteins are integral transmembrane proteins ; that is they exist permanently within and span the membrane across which they transport substances.
