Tlhaloso ea Lihlahisoa
Glycerol (kapa glycerine, glycerin) ke motsoako o bonolo oa polyol (tahi ea tsoekere). Ke mokelikeli o se nang 'mala, o se nang monko, o nang le viscous o sebelisoang haholo mekhoeng ea meriana. Glycerol e na le lihlopha tse tharo tsa hydroxyl tse ikarabellang bakeng sa ho qhibiliha ha eona metsing le tlhaho ea eona ea hygroscopic. Mokokotlo oa glycerol o bohareng ba lipids tsohle tse tsejoang e le triglycerides. Glycerol e na le tatso e monate ebile e na le chefo e fokolang.Indasteri ea lijoLijong le linong, glycerol e sebetsa e le monko o monate, mokelikeli le monate, 'me e ka thusa ho boloka lijo. E boetse e sebelisoa e le setlolo lijong tse rekisoang tse nang le mafura a tlase (mohlala, likuku), hape e le ntho e matlafatsang liqueurs. Glycerol le metsi li sebelisoa ho boloka mefuta e itseng ea makhasi. E le sebaka sa tsoekere, e na le hoo e ka bang 27 kilocalories ka teaspoon (tsoekere e na le 20) 'me ke 60% e monate joaloka sucrose. Ha e fepe libaktheria tse etsang li-plaque 'me li baka mekoti ea meno. Joalo ka setlatsetso sa lijo, glycerol e ngotsoe joalo ka nomoro ea E422. E eketsoa ho icing (frosting) ho thibela ho beha ka thata haholo.Joalokaha e sebelisoa lijong, glycerol e arotsoe ke American Dietetic Association e le lik'habohaedreite. US Food and Drug Administration (FDA) lebitso la lik'habohaedreite le kenyelletsa li-macronutrients tsohle tsa caloric ntle le liprotheine le mafura. Glycerol e na le lik'halori tse ts'oanang le tsoekere ea tafoleng, empa index ea glycemic e tlase le tsela e fapaneng ea metabolism ka har'a 'mele, kahoo babuelli ba bang ba lijo ba amohela glycerol e le monate o lumellanang le lijo tse fokolang tsa lik'habohaedreite. litokisetso tsa tlhokomelo ea botho, haholo-holo e le mokhoa oa ho ntlafatsa boreleli, ho fana ka lubrication le e le humectant. E fumaneha ho allergen immunotherapies, li-syrups tsa ho khohlela, li-elixirs le li-expectorants, sesepa sa meno, se hlatsoang molomo, lihlahisoa tsa tlhokomelo ea letlalo, tranelate ea ho kuta, lihlahisoa tsa tlhokomelo ea moriri, sesepa le litlolo tsa botho tse thehiloeng metsing. Ka liforomo tsa litekanyetso tse tiileng joalo ka matlapa, glycerol e sebelisoa e le ntho e ts'oarang letlapa. Bakeng sa tšebeliso ea batho, glycerol e khetholloa ke US FDA har'a lino tse tahang tsa tsoekere e le caloric macronutrient.Glycerol ke karolo ea sesepa sa glycerin. Oli ea bohlokoa e eketsoa bakeng sa monko o monate. Sesepa sa mofuta ona se sebelisoa ke batho ba nang le letlalo le bobebe, le halefileng habonolo hobane se thibela ho omella ha letlalo ka lintho tsa lona tse mongobo. E hulela mongobo holim'a letlalo 'me e liehe kapa e thibela ho omella ho feteletseng le ho tsoa mouoane. Leha ho le joalo, ba bang ba bolela hore ka lebaka la thepa ea glycerin e monyang mongobo, e ka ba tšitiso ho feta molemo.Glycerol e ka sebelisoa e le laxative ha e kenngoa ka har'a rectum ka suppository kapa e nyenyane-volume (2-10 ml) (enema) sebopeho; e halefisa mucosa ea anal mme e etsa hore ho be le phello ea hyperosmotic.E nkoa ka molomo (hangata e kopantsoe le lero la litholoana ho fokotsa tatso ea eona e monate), glycerol e ka baka ho fokotseha ka potlako, ka nakoana khatellong ea ka hare ea leihlo. Ena e ka ba thuso ea pele ea kalafo ea tšohanyetso ea khatello ea mahlo e phahameng haholo.
