- Alangium chinense — A species of small to medium-sized deciduous tree or shrub in the genus Alangium, native to a wide region spanning China, the Caucasus, South Asia, and parts of tropical Africa; a plant structurally characterized by variable leaf shapes (often lobed) and creamy-white flowers with recurved petals. In traditional Chinese medicine (known as Ba Jiao Feng), its roots and bark are empirically used for their analgesic and anti-inflammatory effects in treating rheumatism, although the plant contains potent alkaloids (such as alangine) that impart high toxicity and require rigorous processing.
- Alangium platanifolium — A species of large shrub or small tree in the genus Alangium, native to the temperate and subtropical regions of East Asia, particularly in Japan, Korea, and eastern China; an ornamental plant structurally remarkable for its large, palmate-lobed leaves that strikingly resemble those of the plane tree (Platanus). The species produces fragrant white flowers with long, linear petals that open during the summer, followed by dark blue drupe fruits, being valued in landscape design for its exotic appearance and decorative foliage.
- Alanine — A non-essential, structurally aliphatic amino acid with the chemical formula CH3-CH(NH2)-COOH, which is a constituent of most proteins in living organisms; it plays a fundamental role in glucose metabolism through the glucose-alanine cycle, allowing muscles to convert amino acids into energy and transport residual nitrogen to the liver for elimination as urea. This organic compound actively participates in protein synthesis, immune system support, and blood sugar regulation.
- Allanto- — A combining form or structural prefixoid used in international medical and biological terminology to introduce references to the allantois (a sac-like embryonic membrane), to allantoic acid, or to anatomical structures shaped like a sausage or an elongated sac. This lexical element serves to construct complex neologisms within the disciplines of embryology, urology, and histology.
- Allantoid — Pertaining to the allantois, or having the shape of a sausage or an elongated sac; allantoidian. In structural medical and biological terminology, the term describes the morphological configuration of certain embryonic appendages, fetal membranes, or elongated cavitary structures that appear during the early development phases of amniote vertebrates.
- Allantois — A sac-like, highly vascular embryonic membrane characteristic of reptiles, birds, and mammals, developing as a diverticulum of the fetal hindgut; a structural organ with vital functions in embryonic respiration, excretion, and nutrition, actively participating, in placental mammals, in the formation of the umbilical cord and placenta through its dense network of blood vessels.
- Allantoin — An organic compound with the chemical formula C4H6N4O3, resulting from the oxidation of uric acid in purine metabolism in most mammals (except higher primates and humans) or extracted from plants such as comfrey (Symphytum officinale); an active substance structurally recognized for its keratolytic, healing, anti-irritant, and intense moisturizing properties. Due to its capacity to stimulate cell proliferation and rapid regeneration of skin tissues, it is widely used in the dermatocosmetic industry for formulating creams, lotions, and ointments intended for sensitive or damaged skin.
- Alkalemia — The physiological or pathological state characterized by an increase in blood alkalinity beyond normal limits, resulting in an arterial pH value greater than 7.45. This structural acid-base imbalance can be caused by the accumulation of bases or the excessive loss of acids from the body, being closely correlated with severe metabolic or respiratory disorders.
- Alkalize — To make or become alkaline; to alter the chemical reaction of a solution, soil, or organic environment by increasing the proportion of bases and raising the pH above the neutral value of 7. In medicine and dietetics, it refers to the process of reducing acidity in the body through the consumption of specific foods or substances.
- Alkalinized — Having undergone the process of alkalinization; a medium, solution, soil, or organic substance whose chemical reaction has been altered by adding bases, raising its pH above the neutral value of 7. In the food industry, the term describes specific products, such as cocoa powder treated to reduce bitterness and improve solubility.
- Alkaline therapy — A medical therapeutic method consisting of the internal or external administration of alkaline substances (such as sodium bicarbonate or alkaline mineral waters) for the purpose of neutralizing gastric hyperacidity, altering urinary pH, or correcting metabolic acidosis in the body. This structural treatment helps restore fluid homeostasis in various chronic diseases.
- Alkalize — To make or become alkaline; to alter the chemical reaction of a medium by increasing the concentration of bases and raising the pH above the neutral value of 7. The term functions as a direct and frequent synonym of the verb 'alkalinize', being widely utilized in chemistry, medicine, agronomy, and industrial neutralization processes.
- Alkalized — Having undergone the process of alkalization or alkalinization; a medium, soil, liquid, or product whose acidity has been neutralized or reduced by adding bases, raising its pH above the value of 7. In the food industry, it specifically applies to cocoa powder obtained through the Dutch process to improve its solubility and tone down its astringent taste.
- Alkalosis — A disturbance of the acid-base balance in the body, characterized by an increase in plasma pH above the normal value of 7.45, resulting from the accumulation of alkaline substances (bases) or excessive loss of acids. It can be metabolic (triggered by severe vomiting or bicarbonate ingestion) or respiratory (caused by hyperventilation).
- Aldosterone — A mineralocorticoid steroid hormone secreted by the zona glomerulosa of the adrenal cortex, playing an essential role in regulating fluid-electrolyte balance and blood pressure. It acts upon the distal tubules of the kidneys, stimulating sodium and water reabsorption while promoting potassium and hydrogen excretion.
- Almglocke — An idiophonic percussion musical instrument derived from traditional cattle bells worn in the Alpine region; a set of chromatically or diatonically tuned bells made of forged metal, used in modern and avant-garde orchestral music to produce clear, resonant sounds with a unique pastoral quality.
- Alpinia calcarata — The scientific Latin designation for a perennial herbaceous plant species within the Alpinia genus, Zingiberaceae family, native to India and Sri Lanka. This aromatic and medicinal plant stands out structurally due to its long, narrow leaves and decorative greenish-white flowers with a red and yellow striped labellum, intensely utilized in traditional medicine (Ayurveda) as an anti-inflammatory and digestive remedy.
- Alpinia galanga — The scientific Latin designation for greater galangal, a perennial herbaceous plant species in the Zingiberaceae family, native to Southeast Asia. This remarkable aromatic plant develops structurally from a fleshy, robust, and knotty rhizome, featuring tall pseudostems and large, lanceolate leaves. It is widely cultivated for its culinary qualities as an essential spice in Thai and Indonesian cuisines, as well as for its antioxidant and digestive therapeutic properties in traditional medicine.
- Alseuosmia — A genus of perennial woody plants, small shrubs native to the temperate and subtropical regions of New Zealand and Australia, representing the type genus of the Alseuosmiaceae family. These shrubs stand out structurally due to their glossy alternate leaves and axillary tubular flowers, often intensely fragrant, studied in botanical taxonomy due to their isolated evolutionary position.
- Alseuosmia macrophylla — The scientific Latin designation for the most representative shrub species within the Alpinia genus, Alseuosmiaceae family, endemic to the moist forests of New Zealand, popularly known as toropapa. This shade-loving plant stands out structurally due to its large, glossy, and lanceolate leaves (macrophylla) and its highly fragrant, reddish or yellowish tubular flowers, utilized as an ecological indicator of intact forest ecosystems.
