Sia metabolism: na asali matakai na mai metabolism

Sia metabolism - shi ne metabolism na fats da mai-kamar abubuwa. Exchange sia kunshi matakai huɗu: tsagawa, sha, tsaka-tsaki da kuma karshe mu'amala.

Sia metabolism: narkewa. Mai lipids, wanda wani bangare ne na abinci samamme ta jiki ne kawai bayan kafin narkewa. A karkashin mataki na narkewa kamar juices, su ne hydrolyzed (cleaved) cikin sauki mahadi (glycerol, mafi girma m acid, sterols, phosphoric acid, nitrogenous sansanonin, mafi girma alcohols, da dai sauransu) suna tunawa mucous membrane na alimentary canal.

The baka abinci dauke da lipids, mechanically yanka, gauraye, wetted da yau da kuma canza kama zuwa com abinci. Shredded abinci taro ta cikin esophagus shiga ciki. Ga su Mix da kuma infiltrate da na ciki da ruwan 'ya'yan itace. Na ciki ruwan ya ƙunshi wani lipolytic enzyme - lipase, wanda zai iya karya saukar kitsen emulsification. Abinci daga ciki to talakawa a kananan rabo shigar da duodenum, jejunum, sa'an nan a cikin ileum. Ga ƙare aiwatar da tsagawa da lipids ana tunawa da su hydrolysis kayayyakin. A sia tsagawa shiga bile, pancreatic ruwan 'ya'yan itace da na hanji da ruwan' ya'yan itace.

Bile - yana da wani asiri, wanda aka hada da hepatocytes. A abun da ke ciki na bile hada da bile acid, kuma pigments, ƙasƙanci kayayyakin na haemoglobin, mucin, cholesterol, lecithin, fats, wasu enzymes, hormones, da dai sauransu Bile yana shan kashi a cikin emulsification na lipids, su narkewa da sha; inganta al'ada hanji suna da hanji. farfado bactericidal sakamako a kan hanji microflora. Bile acid an hada ne daga cholesterol. M acid runtse da surface tashin hankali na mai droplets Emulsifying su ta da mugunya pancreatic ruwan 'ya'yan itace, kazalika da kunna aikin enzymes masu yawa. A cikin kananan hanji da abinci taro seep pancreatic ruwan 'ya'yan itace, wanda qunshi sodium hydrogencarbonate da lipolytic enzymes: lipase, esterase, phospholipase, phosphatase, da dai sauransu

Sia metabolism: sha. Mafi yawa daga lipids tunawa a cikin ƙananan ɓangare na duodenum da kuma na sama jejunum hanjinsu. abinci sia narkewa kayayyakin tunawa da epithelium na villi. A tsotsa surface na epithelial Kwayoyin karu da microvilli. A karshe sia hydrolysis kayayyakin kunshi kananan barbashi na kitse, di- da monoglycerides na mafi girma m acid, glycerol, glycerophosphate, nitrogenous kwasfanta, cholesterol, mafi girma alcohols da phosphoric acid. A cikin manyan hanji lipolytic enzymes ne mãsu fakowa ba. ciwon gamsai ƙunshi kananan adadin phospholipids. Cholesterol, wanda aka ba sucked, rage wa koprosterina tumbi.

Sia metabolism: matsakaici musayar. A lipids yana da wasu siffofin da cewa karya a gaskiyar cewa kananan hanji kawai bayan da tsotsa fission kayayyakin auku resynthesis lipids muhimmi a cikin mutum.

Sia metabolism: karshe musayar. Manyan karshen kayayyakin na sia metabolism ne carbon dioxide da kuma ruwa. A karshen tsaye a waje a matsayin wani ɓangare na fitsari da kuma gumi, jera tumbi, exhaled iska. Carbon dioxide da aka saki farko cikin huhu. A karshe musanya ga wasu kungiyoyin na lipids yana da halaye.

Cuta na sia metabolism. Sia metabolism an gaji da damuwa da yawa a cikin cututtuka, cin zali da kuma wadanda ba communicable cututtuka. A Pathology na sia metabolism lura a take hakkin neurohumoral tsari na narkewa matakai na sha, biosynthesis da lipolysis. Daga cikin cuta da lipid metabolism mafi sau da yawa rajistar kiba.

Kiba - a predisposition zuwa wuce kima karuwa a jikin nauyi saboda matsanancin mai shaida a subcutaneous nama da kuma sauran jikin kyallen takarda da intercellular sarari. Fats aka ajiye a ciki kitsen Kwayoyin a cikin nau'i na triglycerides. Yawan kitsen Kwayoyin bã ya ƙãra, amma ƙãra su fãce da ƙarfi.
