Umzimba lipid: amazinga ayisisekelo fat umzimba

umzimba lipid - kuba umzimba amafutha kanye amafutha-like izinto. Exchange lipid siqukethe izinyathelo ezine: eqhekeza, ukumuncwa, Lesisemkhatsini kanye Ukuhwebelana sokugcina.

umzimba lipid: ukugaya. lipids Iningi, okuyiwona ayingxenye ebaluleke kakhulu ukudla amuncwa wumzimba kuphela emva ukugaya ngaphambi. Ngaphansi isenzo ayo wokugaya ukudla, zingabantu hydrolyzed (wajinge wanamatsela) ibe izakhi elula (glycerol, ephakeme acid okunamafutha, sterols, wali band acid, lezisekelo nitrogen, alcohols ephakeme, njll) esikuthola ulwelwesi lwamafinyila we-canal alimentary.

Ukudla ngomlomo equkethe lipids, athutha usike, exubile, wetted ngamathe futhi uguqulwe com ukudla. Imibengo ukudla mass ngokusebenzisa kuqhoqhoqho kuya esiswini. Lapha uhlanganise futhi ngesinyenyela ijusi esiswini. juice esiswini iqukethe enzyme lipolytic - lipase, okungase sokudiliza amafutha emulsification. Ukudla kusukela esiswini uquqaba izingxenyana ezincane faka duodenum, jejunum, sabe ileum. Lapha uphela inqubo yehlukanise lipids esikuthola kanye nemikhiqizo yabo hydrolysis. Wokuqhekeka lipid iqhaza Bile, juice pancreatic juice emathunjini.

Bile - kuyimfihlo, okuyinto kuhlelwe umqondo ngu hepatocytes. I yokwakheka Bile zihlanganisa Bile acid, nama-zombala, imikhiqizo nokwehliswa kwesithunzi elithwala umoya-mpilo, mucin, cholesterol, lecithin, amafutha, ezinye enzyme, ama-hormone, njll Bile kuthatha iqhaza emulsification of lipids, ukugaya yabo futhi ukumuncwa; ikhuthaza peristalsis evamile wamathumbu; ubukisa umphumela amagciwane phezu microflora emathunjini. Bile acid kuthiwa umqondo kusuka cholesterol. Okunamafutha acid wehlise amaphaphu kobuso amaconsi amafutha emulsifying kubo sikhuthaze uketshezi juice pancreatic, kanye kusebenze isenzo enzyme eziningi. Emathunjini amancane mass ukudla seep juice pancreatic, okuyindawo ehlanganisa sodium hydrogencarbonate futhi lipolytic enzyme: lipase, esterase, phospholipase, phosphatase, njll

umzimba lipid: ukumuncwa. Iningi lipids angena engxenyeni engezansi duodenum kanye engenhla jejunum namathumbu. ukudla lipid imikhiqizo ukugaya ithathe epithelium we villi. Ebusweni ukuncela of amaseli EPITHELIAL kukhuphuke ngo microvilli. Yokugcina imikhiqizo lipid hydrolysis aqukethe izinhlayiya ezincane fat, thini futhi monoglycerides of acid ephakeme okunamafutha, glycerol, glycerophosphate, lezisekelo nitrogen, cholesterol, alcohols ephakeme futhi wali band acid. Emathunjini ezinkulu enzyme lipolytic bengekho. ikholoni isikhwehlela iqukethe esincane phospholipids. Cholesterol, okungasekelwe ukusivumela, sehliselwe indle koprosterina.

umzimba lipid: exchange Lesisemkhatsini. Esikhathini lipids ke inezici ezithile abalele yokuthi emathunjini amancane nje ngemva imikhiqizo ukuncela ukuqoqwa kwenzeka resynthesis lipids esivela indoda.

umzimba lipid: exchange sokugcina. Imikhiqizo ezinkulu ekupheleni lipid umzimba kukhona i-carbon dioxide futhi amanzi. Lesi sakamuva ivelele njengengxenye umchamo nomjuluko, ngokwengxenye endleni, emoyeni ngamakhala. Carbon dioxide ukhululeka ngokuyinhloko emaphashini. Ukushintsha sokugcina amaqembu athile lipids has izici zayo siqu.

Iziyaluyalu lipid umzimba. umzimba lipid kuyaphazamiseka yezifo eziningi ezithathelwanayo, koda futhi ezithelelanayo. I zokugula of lipid umzimba waphawula ayephuli isiqondiso neurohumoral of ukugaya izinqubo ukumuncwa, biosynthesis futhi lipolysis. Phakathi iziyaluyalu lipid umzimba avame ukubhalisa ukukhuluphala.

Ukukhuluphala - nezici ezithile ukuze ukwanda ngokweqile e esisindo ngenxa ngokweqile amafutha sebethule e nezicubu ongama nezinye izicubu zomzimba futhi isikhala intercellular. Amafutha imali ngaphakathi amaseli fat ngesimo triglyceride. Isibalo amaseli fat ayikhuphuki, kodwa kuphela kwandisa umthamo wabo. Kuyinto lokhu hypertrophy amaseli fat kuyisici esiyinhloko akhuluphale ngokweqile.
