A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential – as the body can function without them – or because their actions are obscured by nutrients fulfilling the function.
Drosomycin, an example of a peptide. Peptides are short chains of amino acids linked by peptide bonds. [1] [2] A polypeptide is a longer, continuous, unbranched peptide chain. [3] Polypeptides that have a molecular mass of 10,000 Da or more are called proteins. [4]
Some prominent examples of biogenic monoamines include: Monoamine neurotransmitters. Imidazoleamines. Histamine – a substance derived from the amino acid histidine that acts as a neurotransmitter mediating arousal and attention, as well as a pro-inflammatory signal released from mast cells in response to allergic reactions or tissue damage.
This peptide consists of a core peptide segment which is typically preceded (and occasionally followed) by a leader peptide segment and is typically ~20-110 residues long. The leader peptide is usually important for enabling enzymatic processing of the precursor peptide via aiding in recognition of the core peptide by biosynthetic enzymes and ...
Due to their ability to break down proteins and peptides, they are used in to help digest proteins, regulate peptide-mediated effects, and break down bioactive peptides. [4] Aminopeptidase N (AP-N) is particularly abundant in the brush border membranes of the kidney, small intestine, and placenta, and is also rich in the liver. [4]
Bioactive agents are substances that can influence an organism, tissue or cell. Examples include enzymes, drugs, vitamins, phytochemicals , and bioactive compounds . Bioactive agents can be incorporated into polymers , [ 1 ] [ 2 ] which has applications in drug delivery and commercial production of household goods and biomedical devices. [ 2 ]
[16] [28] TOP, a ubiquitous cytosolic oligopeptidase, is a remarkable example of how this enzyme could play an essential role in immune defense against cancer cells. [27] It has also been successfully used as a hook to fish novel bioactive peptides from cytosol of cells. [31]
Nonribosomal peptides are also found in higher organisms, such as nudibranchs, but are thought to be made by bacteria inside these organisms. [1] While there exist a wide range of peptides that are not synthesized by ribosomes, the term nonribosomal peptide typically refers to a very specific set of these as discussed in this article.
