"Chelicera" Natural Recordings by Native Speakers
Chelicera refers to the pincer-like structures that are used for grasping and tearing food or other materials by certain arachnids, such as spiders and scorpions.
Chelates are compounds that contain a central metal ion, such as calcium or iron, surrounded by a organic molecule or ion, typically an amino acid or a sugar molecule. The central metal ion is bonded to the surrounding molecule through coordinate covalent bonds, creating a ring-shaped structure. Chelates are often used in biochemistry and nutrition to facilitate the absorption of essential metals and minerals by the body. Examples of chelates include EDTA (ethylenediaminetetraacetic acid) and citrate, which are commonly used in dietary supplements to enhance the bioavailability of minerals such as calcium, magnesium, and iron.
Chelation refers to the process of forming a stable complex between a metal ion and a ligand, which is a molecule or ion that can donate electrons to bind with the metal ion. This complex, known as a chelate, is typically more stable than the original metal ion because of the increased electrostatic attraction between the ion and the ligand. Chelation is often used in medicine to treat heavy metal poisoning, remove excess metals from the body, and reduce the risk of disease associated with certain metals.
Chelerythrine is a chemical compound and an alkylpyrrolizine alkaloid found in the plant Chelidonium majus, also known as greater celandine. It has been found to have immunosuppressive and anti-inflammatory properties, and has been researched for its potential use in the treatment of various diseases, including cancer, allergic reactions, and inflammatory disorders.
