"Chelicerae" Natural Recordings by Native Speakers
Chelicerae refers to the appendages found in spiders, scorpions, and some arachnids that are used for capturing and manipulating prey, as well as for defense and sensory purposes. In spiders, the chelicerae are usually paired and are located on the anterior (front) part of the cephalothorax (the forefront part of the spider's body). The chelicerae are typically stout and hairy, and are used to inject venom into prey, as well as to manipulate and dismember it.
Chelating refers to the process of forming a strong chemical bond between a metal ion and an organic molecule, typically a ring-shaped one, which acts as a Lewis base. This binding strongly and reversibly holds the metal ion, rendering it unavailable for biochemical reactions. Chelating agents are often used in biochemistry and medicine to sequester metal ions, such as calcium, magnesium, or zinc, to regulate their availability in the body.
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.
Chelatometry is a noun that refers to the measurement of the ability of a substance to form a complex with a metal ion or ions, typically used to determine the affinity of a ligand for a metal ion.
Chelators are synthetic or naturally occurring molecules that have the ability to bind and remove metal ions from biological fluids or enzymes. They are used to treat metal toxicity, such as lead or mercury poisoning, and are also used in medical imaging and cancer treatment. Chelators can bind to metal ions in a specific conformation, called a chelate, which allows them to remove them from the body or prevent them from participating in enzymatic reactions.
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.
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.
Chelicerates is a subphylum of arthropods that includes arachnids, such as spiders and scorpions, and sea spiders (pantopods). The term "chelicerate" comes from the Greek words "chelē," meaning "claw," and "keras," meaning "horn." It refers to the distinctive pair of clbrowse-like structures called chelicerae, which are used for feeding, sensory perception, and defense by these arthropods.
Cheliceriform refers to a group of arthropods that includes arachnids, pseudoscorpions, and sea spiders. The term refers to the characteristic pincer-like appendages called chelicerae that are used for feeding and defense. Cheliceriforms also have a standardized body plan, which includes a cephalothorax (head- torso) and an abdomen, and they have a four-part circulatory system.
Chelicerous refers to something that is having chelicerae, which are appendages similar to mouthparts found in certain arthropods, such as spiders, scorpions, and ticks. Chelicerous organisms typically use their chelicerae to capture and inject venom into their prey. The term "chelicerous" can also describe the characteristics or features of these organisms, such as their simple eyes, segemented bodies, and jointed limbs.
