"Aglycones" Natural Recordings by Native Speakers
Aglycones are the non-sugar parts of glycosides, which are compounds formed when a sugar molecule is chemically bonded to another compound, such as a hormone or a toxin. In other words, aglycones are the active compounds that remain after the removal of the sugar moiety from a glycoside. They can have various biological activities and are found in different natural sources like plants, where they often contribute to the plant's color, flavor, or medicinal properties.
1. Aglycones are the sugar-free forms of glycosides, which are compounds found in various plants. They play a crucial role in the pharmacological properties of natural products.
markdown
Example: The aglycone of quercetin, a flavonoid found in fruits and vegetables, exhibits strong antioxidant activity.
2. In the process of hydrolysis, glycosides are broken down to release their corresponding aglycones, making them more bioavailable for absorption in the body.
markdown
Example: When consumed, steviol glycosides from stevia are hydrolyzed in the gut, releasing the active aglycone steviol, which has a sweet taste.
3. Aglycones can have diverse chemical structures, such as phenols, alkaloids, or terpenoids, and their biological activities often differ from their glycosidic precursors.
markdown
Example: The aglycone form of genistein, a tyrosine kinase inhibitor, has stronger anticancer effects than its glycosylated version found in soybeans.
4. Some dietary supplements and functional foods are enriched with aglycones to enhance their health benefits, like improving cardiovascular health or supporting weight management.
markdown
Example: Resveratrol aglycone, a polyphenol found in red wine, is often used in supplements due to its potential anti-inflammatory and cardioprotective properties.
5. The stability and bioactivity of aglycones can be influenced by factors such as pH, enzymes, and intestinal microbiota, affecting their absorption and efficacy in the human body.
markdown
Example: The bioavailability of anthocyanidin aglycones, responsible for the color of berries, can be enhanced by the presence of specific gut bacteria that help break down their glycosidic bonds.
"Agley" is an old-fashioned or dialectical term that means "in disorder," "askew," "amiss," or "out of line." It typically suggests something is not in its proper place or is functioning incorrectly.
"Aglio" is an Italian word that refers to garlic. It is a bulbous plant with a strong, pungent flavor commonly used in cooking to add taste and aroma to dishes.
Agliophobia refers to an abnormal or irrational fear of pain. It is a specific phobia characterized by a strong and persistent avoidance of anything that may cause physical pain or discomfort. People with this phobia may experience severe anxiety, panic attacks, or even avoidance behavior when faced with situations or objects that they associate with potential pain.
Aglossal refers to the condition of not having a tongue or a deficiency in the development of the tongue. It is often used in medical contexts to describe individuals with先天性无舌或舌发育不全, which can affect speech, eating, and other functions involving the tongue.
Aglossia is a medical condition characterized by the absence or severe impairment of speech production, often due to brain damage or developmental issues. It is also known as mutism or inability to speak. People with aglossia may understand language but have difficulty forming words or producing vocalizations.
Aglow refers to a state of emitting or reflecting light, often with a gentle or warm glow. It can also describe a feeling of excitement, happiness, or contentment that is visible on someone's face or in their demeanor.
Agglutination refers to the process of joining or sticking together of small particles or elements, often forming a cluster or mass. In linguistics, it specifically denotes a linguistic process where one word is formed by adding multiple affixes or morphemes together, resulting in a long complex word. For example, in Turkish, the word "kitabımız" means "our book," where "kitab" means "book," and the suffixes "-ı" (possessive), "-nın" (second person plural), and "-ız" (first person plural) are agglutinated.
Aglycone refers to a sugar-free compound that remains after a glycoside is hydrolyzed or cleaved. It is typically a sterol, terpenoid, or other organic compound that was previously bonded to a sugar molecule (glycone) in a glycosidic bond. In other words, it is the non-sugar part of a glycoside.
