Lipid metabolism: mekhahlelo motheo ea metabolism mafura

Lipid metabolism - e ke metabolism ea mafura le mafura a-joaloka dintho. Phapanyetsano lipid na le mehato e mene: petsoha, absorption, lipakeng le fapanyetsana ho qetela.

Lipid metabolism: tshilo ya dijo. lipids ho fetisisa, e leng ke e le karolo ea lijo tsa ananelang 'mele feela ka mor'a tshilo ya dijo pele. Tlas'a bohato la dijusi tshilong ya dijo, ba hydrolyzed (khomaretse) e be metsoako e bonolo (glycerol, phahame mafura acid, sterols, acid phosphoric, makalana nitrogenous, alcohols phahameng, joalo-joalo) li ananelang mucous lera la kanale alimentary.

Lijo ka molomo e nang le lipids, mechanically khaola, e tsoakiloeng, wetted ka mathe le ho fetoloa Song lijo. Shredded lijo boima ka metso ho kena ka mpeng. Mona ba kopanya le kena ka lenyele ka lero gastric. lero Gastric na le lipolytic potlakisang tsebetso ea lik'hemik'hale - lipase, e leng se ka heletsa mafura emulsification. Lijo ho tswa ho mala ho batho ba tloaelehileng ka likarolo tse nyenyane kena duodenum, jejunum, 'me joale ka ileum ena. Mona e fella ka tshebetso ya ho petsoha le lipids ba ananelang le lihlahisoa tsa bona hydrolysis. The lipid petsoha seabo bile, lero pancreatic le lero mala.

Bile - ho e le lekunutu, e leng e tsa maiketsetso ke hepatocytes. The ka bophara bile kenyeletsa bile acid, le ka mebala, ho senyeha ha lihlahisoa tsa haemoglobin, mucin, k'holeseterole e, lecithin, mafura, tse ling enzyme, li-hormone, joalo-joalo Bile e nkang karolo e emulsification tsa lipids, tshilo ya dijo ea bona 'me absorption; kgothaletsa peristalsis tloaelehileng ea mantle a ka; hlahisa phello e bactericidal ka microflora le mala. Bile acid ba tsa maiketsetso tloha k'holeseterole. Tse mafura acid e fokotsa tsitsipano holim 'a marotholi mafura emulsifying ba susumelletsa ho secretion ea lero pancreatic, hammoho le ebe o kenya tshebetsong le bohato ba enzyme tse ngata. Ka intestine tse nyenyane boima lijo seep lero pancreatic, e kenyelletsa ditokiseletso sodium hydrogencarbonate le lipolytic enzyme: lipase, esterase, phospholipase, phosphatase, joalo-joalo

Lipid metabolism: absorption. Boholo ba lipids kena karolong e ka tlaase ea e duodenum le ka holimo jejunum mala. lijo lipid tshilo ya dijo lihlahisoa ananelang le epithelium tsa villi ena. The fire holim 'a lisele tse epithelial eketseha ka microvilli. Ho qetela lipid hydrolysis lihlahisoa bopilwe likaroloana tse nyenyane tsa mafura, di- le monoglycerides ea acid e phahameng tse mafura, glycerol, glycerophosphate, makalana nitrogenous, k'holeseterole e, alcohols phahameng le asiti phosphoric. Ka intestine kgolo enzyme lipolytic ke le siyo. mala mucus na le e nyenyane ea phospholipids. K'holeseterole, o sa antseng, fokotswa ho mantle koprosterina.

Lipid metabolism: lipakeng phapanyetsano. Ka lipids ho e na le tse ling tse tse larileng ka ka 'nete ea hore intestine nyane feela ka mor'a lihlahisoa fire fission le hlaha resynthesis lipids tlholeho ho motho.

Lipid metabolism: qetela phapanyetsano. The kgolo qetellong lihlahisoa tsa metabolism lipid ke carbon dioxide le metsi. Ea bobeli lia ikhetha ka ho ba karolo ea moroto le mofufutso, karolo e 'ngoe mantle, exhaled moea. Carbon dioxide e lokolloa ka sehloohong matšoafo. Phapanyetsano ho qetela bakeng sa lihlopha tse itseng tsa lipids na le litšobotsi tse ba lona.

Mafu a ea metabolism lipid. Lipid metabolism e tšoenngoa ka mafu a mangata a tšoaetsanoang, itaolang le batho bao e seng tshwaetsaneng. The bolwetse ea metabolism lipid hlokometse ka tlōla molao oa tsamaiso neurohumoral tsa dithulaganyo tshilo ya dijo ea absorption, biosynthesis le lipolysis. Har'a mafu a ea metabolism lipid hangata ka ho fetisisa ngodisa botenya.

Botenya - e predisposition ho keketseho ea ka tsela e feteletseng ka boima ba 'mele ka lebaka la ho ka tsela e feteletseng mafura deposition ea dinama tse nyenyane tse subcutaneous le lisele tse ling tse' mele le sebaka intercellular. Fats li beha ka hare ho lisele tse mafura ka mokgwa wa triglycerides. palo ea lisele tse mafura ha eketseha, empa ho eketsa feela bophahamo ba modumo tsa bona. Ho hypertrophy ena ea lisele mafura ke Ntlha e ka sehloohong e botenya.
