Turkesterone
Turkesterone is a phytoecdysteroid found in numerous plant species, including '' Ajuga turkestanica'', various ''Vitex'' species, ''Triticum aestivum'', and ''Rhaponticum acaule''.

Ecdysterone
20-Hydroxyecdysone (ecdysterone or 20E) is a naturally occurring ecdysteroid hormone which controls the ecdysis (moulting) and metamorphosis of arthropods. It is therefore one of the most common moulting hormones in insects, crabs, etc. It is also a phytoecdysteroid produced by various plants, including ''Cyanotis vaga'', ''Ajuga turkestanica'' and ''Rhaponticum carthamoides'' where its purpose is presumably to disrupt the development and reproduction of insect pests. In arthropods, 20-hydroxyecdysone acts through the ecdysone receptor. Although mammals lack this receptor, 20-hydroxyecdysone may affect mammalian (including human) biological systems ''in vitro'', but there is uncertainty whether any ''in vivo'' or physiological effects occur. 20-Hydroxyecdysone is an ingredient of some supplements that aim to enhance physical performance. In humans, it is hypothesized to bind to the estrogen receptor beta (ERβ) protein-coding gene. Sources in arthropods The primary sources of 20-h ...

Phytoecdysteroid
Phytoecdysteroids are plant-derived ecdysteroids. Phytoecdysteroids are a class of chemicals that plants synthesize for defense against phytophagous (plant eating) insects. These compounds are mimics of hormones used by arthropods in the molting process known as ecdysis. When insects eat the plants with these chemicals they may prematurely molt, lose weight, or suffer other metabolic damage and die. Chemically, phytoecdysteroids are classed as triterpenoids, the group of compounds that includes triterpene saponins, phytosterols, and phytoecdysteroids. Plants, but not animals, synthesize phytoecdysteroids from mevalonic acid in the mevalonate pathway of the plant cell using acetyl-CoA as a precursor. Over 250 ecdysteroid analogs have been identified so far in plants, and it has been theorized that there are over 1,000 possible structures which might occur in nature. Many more plants have the ability to "turn on" the production of phytoecdysteroids when under stress, animal attack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ajuga Turkestanica
''Ajuga turkestanica'' is a herbaceous flowering plant native to Central Asia. It was first described in 1894. Description ''A. turkestanica'' is a perennial herbaceous plant reaching heights between 40 and 60 cm. The plant is typically found in populations between 10 and 300, and appear more frequent within ''Artemisia'' complexes. The leaves are an elliptical oblong shape, straight-edged and with a pointed tip. It will flower between May and June. The flowers are small, pink, and located within the axil of two leaves. The fruit consists of four nuts, a characteristic of the Lamiaceae family. Fruit is born by the end of May. Distribution ''A. turkestanica'' is native to the Pamir-Alay mountain ranges of Central Asia, notably within the Surxondaryo Region of Uzbekistan. The species has also been observed within the low mountain regions of southern Tajikistan. It grows in rocky clay conditions up to elevations of approximately 2500 metres.

Triticum Aestivum
Common wheat (''Triticum aestivum''), also known as bread wheat, is a cultivated wheat species. About 95% of wheat produced worldwide is common wheat; it is the most widely grown of all crops and the cereal with the highest monetary yield. Taxonomy Numerous forms of wheat have evolved under human selection. This diversity has led to confusion in the naming of wheats, with names based on both genetic and morphological characteristics. List of common cultivars * Albimonte * Manital Phylogeny Bread wheat is an allohexaploid (an allopolyploid with six sets of chromosomes: two sets from each of three different species). Of the six sets of chromosomes, two come from ''Triticum urartu'' (einkorn wheat) and two from a species related to ''Aegilops speltoides''. This spontaneous hybridisation created the tetraploid species ''Triticum turgidum'' (an ancestor of wild emmer wheat and durum wheat) 580,000–820,000 years ago. The last two sets of chromosomes came from wild goat-gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anabolic Steroid
Anabolic steroids, also known more properly as anabolic–androgenic steroids (AAS), are steroidal androgens that include natural androgens like testosterone (medication), testosterone as well as synthetic androgens that are structurally related and have similar effects to testosterone. They increase protein within cell (biology), cells, especially in skeletal muscles, and also have varying degrees of virilization, virilizing effects, including induction of the development and maintenance of male, masculine secondary sexual characteristics such as the growth of facial hair, facial and body hair. The word ''anabolic'', referring to anabolism, comes from the Greek ἀναβολή ''anabole'', "that which is thrown up, mound". Androgens or AAS are one of three types of sex hormone agonists, the others being estrogen (medication), estrogens like estradiol (medication), estradiol and progestogens like progesterone (medication), progesterone. AAS were synthesized in the 1930s, and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
