"Lanthionine" Natural Recordings by Native Speakers
Lanthionine is a type of organic compound that is formed from the condensation of a molecule of lanthionine acid with an amino group of a protein. It is a modified amino acid and is found in certain proteins, such as wool keratin and hair keratin. Lanthionine is known to have antioxidant properties and has been researched for its potential therapeutic uses, including the treatment of certain skin disorders and the prevention of cancer.
Lanthanite is a mineral of the type known as silicate mineral. It is a rare earth element, specifically a member of the group of minerals known as cerium group minerals, which get their name from the presence of the element cerium. Like other rare earth elements, lanthanites have unique properties that make them useful for a variety of applications. They are often used in the production of electronics, batteries, and catalysts.
Lanthanoid refers to a series of chemical elements with atomic numbers 57 through 71, also known as the “inner transition metals”. These elements are located in the bottom-left corner of the periodic table and include lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, and yttrium. They are often referred to collectively as the "rare earth" elements, although not all rare earth elements are lanthanoids.
Lanthanotus refers to a genus of reptiles commonly known as flat-tailed swifts or gliding lizards.
Lanthionization is a process in which an amino acid is converted into a lanthionine residue, which is a type of disulfide bond. This occurs when the amino acid cysteine is cyclized and condensed with another cysteine residue, forming a characteristic four-membered ring structure. Lanthionization is a common post-translational modification found in some peptides and proteins, and plays a role in their structural and functional properties.
The adjective "lanuginous" means covered with fine soft hair, like wool or down. It can be used to describe an animal's fur or feathers that is soft, fluffy, and usually gray or white in color. For example, a lanuginous mole is a type of small mammal that has a soft, woolly coat. The word is often used in biological or scientific contexts to describe the physical characteristics of an animal or plant.
Lanugo is a fine, soft, and downy hair that is present on the skin of a fetus or a newborn baby. It is a normal and temporary feature of fetal development, and it usually falls off or is shed shortly after birth. The term "lanugo" is derived from the Latin word "lanugo," which means "wool" or "fleece."
