IGF-1 LR3 on modifitseeritud versioon, millel on struktuurilised muudatused, mis v\u00e4hendavad selle sidumisvalgu afiinsust insuliinisarnaseid kasvufaktoreid siduvate valkude (IGFBP-de) suhtes, et tagada loomulikust IGF-1-st pikemaajalisem aktiivsus.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">IGF-1 LR3-s on kolmas aminohape glutamiinhappe asemel arginiin ja peptiidil on N-terminuses 13 t\u00e4iendavat aminohapet. Need erinevused t\u00e4hendavad, et see on IGF-1 retseptori agonist, millel on mitmed eelised, sealhulgas kolm korda suurem tugevus v\u00f5rreldes IGF-1-ga. Samuti on selle poolestusaeg umbes 20 kuni 30 tundi \u2013 mis on palju pikem kui loodusliku hormooni 12 kuni 15 tundi \u2013, pakkudes looduslikust IGF-1-st pikemaajalisemat toimet. L\u00f5puks tagab IGF-1 LR3 t\u00e4nu oma ekstra aminohapetele parema metaboolse stabiilsuse.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Teiste s\u00f5nadega, IGF-1 LR3 modifikatsioonid suurendavad selle uurimispotentsiaali lihaste arengu ja kudede paranemise osas, muutes peptiidi kasulikuks esteetilise ja sportliku uurimist\u00f6\u00f6 mudelites.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">IGF-1 LR3 vs IGF-1 DES<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">IGF-1 teine modiifikatsioon on insuliinisarnane kasvufaktor 1 deletsioon (1-3), mida tavaliselt l\u00fchendatakse kui IGF-1 DES. Sarnaselt IGF-1 LR3-le on see s\u00fcnteetiline peptiid, mis on loodud loodusliku IGF-1 kasulike omaduste tugevdamiseks. IGF-1 DES-i puhul saavutatakse see esimese kolme N-terminaalse aminohappe eemaldamisega ilma lisanditeta. Selline modiifikatsioon leiab tegelikult aset ka looduslikult teatud keskkondades, mis viitab sellele, et sellel hormoonil v\u00f5ib teatud olukorras olla organismis oluline roll.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Aminohapete eemaldamine IGF-1 DES-ist v\u00e4hendab peptiidi sidumisafiinsust IGFBP-de suhtes ja suurendab afiinsust IGF-1 retseptori suhtes. Selles osas erineb see IGF-1 LR3-st, millel on v\u00e4henenud afiinsus IGF-1 retseptori suhtes. Just see v\u00e4henenud afiinsus viib pikema poolestusajani.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Teadlased valivad siledate lihasrakkude migratsiooni ja proliferatsiooni uuringuteks tavaliselt IGF-1 DES-i, mitte aga skeletilihaste arengu uurimiseks, nagu on sobilik IGF-1 LR3 puhul. Peptiidil v\u00f5ib olla roll ka neuroloogilistes uuringutes, seda peamiselt seet\u00f5ttu, et seda leidub looduslikult ajukoes.
