This is the list of Schedule II controlled substances in the United States as defined by the Controlled Substances Act. [ 1] The following findings are required for substances to be placed in this schedule: [ 2] The drug or other substance has a high potential for abuse. The drug or other substance has a currently accepted medical use in ...
The Schedule 2 list is one of three lists. Chemicals that can be used as weapons, or used in their manufacture, but that have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 3 is used for chemicals that also have widespread industrial uses. The use of Schedule 1, 2, or 3 chemicals as weapons is banned ...
water hemlock, cowbane, wild carrot, snakeweed, poison parsnip, false parsley, children's bane, death-of-man. Apiaceae. The root, when freshly pulled out of the ground, is extremely poisonous and contains cicutoxin, a central nervous system stimulant that induces seizures. [citation needed]
Definition. Phytochemicals are chemicals of plant origin. [ 1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [ 2][ 3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators.
Flowering Plant. Secondary metabolism produces a large number of specialized compounds (estimated 200,000) that do not aid in the growth and development of plants but are required for the plant to survive in its environment. Secondary metabolism is connected to primary metabolism by using building blocks and biosynthetic enzymes derived from ...
Morphine is produced most predominantly early in the life cycle of the plant. Past the optimum point for extraction, various processes in the plant produce codeine, thebaine , and in some cases negligible amounts of hydromorphone , dihydromorphine , dihydrocodeine , tetrahydro-thebaine, and hydrocodone (these compounds are rather synthesized ...
The Schedule 3 list is one of three lists. Chemicals which can be used as weapons, or used in their manufacture, but which have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 2 is used for chemicals which have legitimate small-scale applications. The use of Schedule 1, 2, or 3 chemicals as weapons is ...
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants. Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds. Plants synthesize phytochemicals for many ...
