Ulwazi nokusebenza
I-enzyme wuhlobo lwamaprotheni olwenza ukusabela kwamakhemikhali emaqenjini omzimba. Ama-enzyme enza imisebenzi ebalulekile edingekayo ekusindeni kuhlanganise nalabo abathintekayo ekugayeni nasekuguleni umzimba. I-enzyme ngayinye inomsebenzi owodwa kuphela, futhi ichaza uhlobo lwama-chemical response reaction.
Ama-Enzyme atholakala ku-Breast Milk
Kunezinhlobo eziningi ze-enzyme ezitholakalayo esifubeni sesifuba somuntu .
La ma-enzyme adlala indima ebalulekile empilweni nasekuthuthukiseni ingane esanda kuzalwa. Ama-enzyme ebisi lwebele abesebenza ngemisebenzi ehlukahlukene, ezinye zazo esingazazi ngisho namanje. Amanye ama-enzyme ayadingeka ekusebenziseni amabele nasekukhiqizeni ubisi lwebele, ezinye ze-enzyme zisiza ingane ngokugaya, kanti ezinye zibalulekile ekuthuthukiseni kwengane. Nazi izinyimba ezibaluleke kakhulu ezitholakala ebisi lwebele.
Amylase
U-Amylase yiyona enzyme e-polysaccharide-digesting digesting. Igalela isitashi. Njengoba izingane zizalwa nge-amylase encane kuphela, zingathola le-enzyme ebalulekile yokugaya ngokusebenzisa ubisi lwebele. Ngemva kwezinyanga eziyisithupha ubudala, i-pancreas yengane iqala ukukhulula i-amylase.
Lipase
Izingane ezisanda kuzalwa zingagaya ngokugcwele futhi zisebenzise amafutha ebisi lwebele ngenxa ye-lipase. I-Lipase iphula amafutha obisi bese ihlukanisa ngamafutha acide nama-glycerol. Izinsana zithola amandla emafutheni ama-acids mahhala, futhi i-lipase yenza lawo mafutha akhululekile atholakala ngaphambi kokugaya kwenzeka emathunjini.
I-Lipase ibuye ibe nomthwalo wemfucumfucu, isiphuzo se-metallic esiqandishelwe ngefriji noma isifuba esidumile esineqhwa kanye ne- thawed ngezinye izikhathi. Ukushisa okubandayo kanye nobisi obisiqhwayo kanye nokuqothula ubisi oluphezulu e-lipase kungabangela amafutha ebisi ukuba aphule ngokushesha ashiye iphunga elimnandi. Kungase kungabi iphunga elihle, kodwa inani lokudla okunomsoco namanje lihle.
I-Protease
I-protease iqinisa ukuwohloka kwamaprotheni. Kunamazinga aphezulu e-protease ebisi lwebele. Kukholelwa ukuthi le enzyme ibalulekile ukugaya ikakhulukazi phakathi nenkathi nje ngemva kokuzalwa .
I-Lactoferrin
I-Lactoferrin iyiprotheni ebopha iron. Kuyasiza ingane ithole insimbi. Futhi, kanye namaseli amhlophe nama- antibodies , i-lactoferrin ibulala amabhaktheriya. I-Lactoferrin inqanda u- E. coli ekuxhumaneni namaseli futhi kusiza ukuvimbela isisu sohudo . I-Lactoferrin nayo ivimbela ukukhula kwe- Candida albicans , i-fungus. Amazinga e-Lactoferrin aphezulu kakhulu ebisini lwebele lesandulela ngculazi kanti amazinga awela phansi njengoba i-lactation iqhubeka.
Lysozyme
I-Lysozyme ivikela usana ngokumelene nama-bacteria anjengo- E. coli no- Salmonella . Amazinga we-lysozyme e-breastmilk akhuphuka ikakhulukazi nxazonke izingane ziqala ukudla ukudla okuqinile. Ukwanda kwe-lysozyme kusiza ukuvikela izingane ezigciwane ezingabangela ukugula nokuhuda.
Amanye ama-enzyme e-Breast Milk
Kukhona ama-enzyme angaphezu kuka-40 aboniswe ebelethweni. Amanye ama-enzyme asebenzayo afaka i-diastase, i-lactose synthetase, ne-lactoperoxidase.
Zikhona I-Enzyme In Formula Yomntwana?
Amafomula omntwana aqukethe ama-enzyme, kodwa eziningi ze-enzyme ezitholakala ebisi lwebele azikho ifomula.
Abakhiqizi be-Formula bengeza ezinye ze-enzyme, kanti ezinye zitholakala ngokwemvelo. Kodwa-ke, ama-enzyme atholakala ebisi aqondile ezilwaneni ezenza ukuthi ubisi. Isibonelo, ubisi lwebele lomuntu luqukethe ama-enzyme olwenzelwe abantwana, futhi ubisi lwezinkomo luqukethe ama-enzyme okwenzelwe ithole lenkomo. Ngakho-ke, uketshezi lwezinsana olusuka ngobisi lwezinkomo alukho amazinga afanayo we-enzyme njengobisi lwebele lomuntu. Ngisho nalapho izinkampani zengeza ama-enzyme ekufomeni usana, angeke zifanane nobisi lwebele.
