Kief (from Arabic كيف kīf, "Joy, pleasure" [1] [2]), sometimes transliterated as keef, also known as "Dust" and "Chief" a.k.a cannabis crystals among other names, refers to the pure and clean collection of loose cannabis trichomes, which are accumulated by being sifted from cannabis flowers or buds with a mesh screen or sieve.
The plant is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. Cannabis has long been used for hemp fibre, hemp seeds and their oils, hemp leaves for use as vegetables and as juice. Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre.
[9] [10] Inside the transcriptomes of glandular trichomes in the cannabis plant, the pathway for cannabinoid production takes place. [9] Beginning with the formation of 3,5,7-trioxododecaneoyl-COA by the condensation reaction between hexanoyl-CoA and malonyl-CoA , catalyzed by type III polyketide synthase (PKS), the product is then used to form ...
Hashish is a cannabis concentrate product composed of compressed or purified preparations of stalked resin glands, called trichomes, from the plant. It is defined by the 1961 UN Single Convention on Narcotic Drugs (Schedule I and IV) as "the separated resin, whether crude or purified, obtained from the cannabis plant".
Cannabis plants can exhibit wide variation in the quantity and type of cannabinoids they produce. The mixture of cannabinoids produced by a plant is known as the plant's cannabinoid profile. Selective breeding has been used to control the genetics of plants and modify
THCA synthase is expressed in the glandular trichomes of Cannabis sativa. THCA synthase may contribute to the self-defense of Cannabis plants by producing THCA and hydrogen peroxide, which are both cytotoxic. Because these products are toxic to the plant, THCA synthase is secreted into the trichome storage cavity. [7]
Datura stramonium also features leaf trichomes as a defensive trait to prevent herbivory. [ 42 ] The physiology of the plant itself is important for understanding patterns of defense as its status as an annual plant limits opportunities for biomass regrowth post-destruction, due to its inability to engage regrowth meristems .
