In their role as healers, witches had access to and knowledge of plants such as deadly nightshade and mandrake which containedalkaloids, chemicals with a powerful effect on the nervous system. Often they would mix these plants with grease or oil to create ointments known asflying salves. When ...
Tomatoes are triggered to turn red bya chemical called ethylene. Ethylene is odorless, tasteless, and invisible to the naked eye. When the tomato reaches the proper green mature stage, it starts to produce ethylene. ... Consistent winds can carry the ethylene gas away from the fruit and slow...
Function; Why it is Recommended Goldenseal, like barberry and Oregon grape root contains significant amount of berberine alkaloids like berberine, hydrastine and canadine. These berberine alkaloids are excellent, non-specific, anti-microbial and anti-fungal agents. Goldenseal has been shown to have po...
plants may be difficult to eat because they contain poisonous chemicals (such as the alkaloids in ragwort). Indeed, 40 years ago Janzen (1975, p. 39) described the herbivores’ view of plants thus: “The world is not coloured green to the herbivore’s eyes, but rather is painted morphine...
How do I get rid of bindweed? As the stems of bindweed typically weave their way round other plants, unfortunately it's often difficult to apply spray weedkiller or you would kill off your plant. Aspot weedkiller such as Round Up Gel can be used. Dab it onto as many leaves as you...
These are nitrogen-based chemical compounds that plants, fungi, and bacteria make to defend themselves against attacks from things like parasites, pathogens, and animals that might eat them. Alkaloids are a big group of chemicals, and have all kinds of different effects. They can be: ...
Anthony's poison arrow frog (Epipedobates anthonyi) (Credit: blickwinkel/Alamy) Batrachotoxin belongs to a large group of chemicals known as alkaloids, which are found in many animals and plants. With the exception of a few non-poisonous species, all other poison dart frogs also use alkaloi...
If so, how do they work? Why are phosphates considered to be environmentally unsafe? Why does refrigerated food take longer to spoil? Explain why ethics and peer review are important to science. What are alkaloids and why do animals in nature stay away from these organic...
David Craik’s work also shows that plants provide not only small GPCR agonists such as alkaloids or terpenoids but also complex peptides such as the cyclotide Kalata B7, a vasopressin/oxytocin receptor agonist [39,40]. Let us stop here without mentioning bacteria and fungi as sources of ...
