Calcium Hydroxyapatite HAP CAS 1306-06-5
Hydroxyapatite, nke a na-akpọkwahydroxylapatite(HA), bụ ụdị ịnweta nke calcium apatite nke nwere usoro Ca5 (PO4) 3 (OH), mana a na-edekarị ya Ca10 (PO4) 6 (OH) 2 iji gosi na cell unit kristal nwere ihe abụọ. Hydroxyapatite bụ njedebe hydroxyl nke otu apatite dị mgbagwoju anya. Dị ọchahydroxyapatite ntụ ntụna-acha ọcha. Apatites na-emekarị nwere ike ịnwe agba aja aja, odo, ma ọ bụ akwụkwọ ndụ akwụkwọ ndụ, nke yiri ngbanwe nke fluorosis eze.
Ruo 50% site na olu na 70% site n'ịdị arọ nke ọkpụkpụ mmadụ bụ ụdị mgbanwe nke hydroxyapatite, nke a maara dị ka ọkpụkpụ ọkpụkpụ. A na-ahụkwa kristal hydroxyapatite n'ime obere calcifications, n'ime gland pineal na akụkụ ndị ọzọ, nke a maara dị ka corpora arenacea ma ọ bụ 'ụbụrụ ụbụrụ'.
Ngwa
1. Hydroxyapatite dị na ọkpụkpụ na ezé; Ọkpụkpụ bụ isi nke kristal HA gbakọrọ na matrix collagen - 65 ruo 70% nke oke ọkpụkpụ bụ HA. N'otu aka ahụ HA bụ 70 ruo 80% nke oke dentin na enamel na ezé. Na enamel, matrix maka HA bụ amelogenins na enamelins na-emepụta kama collagen.
Ndokwa Hydroxylapatite na akwara gburugburu nkwonkwo na-ebute ọnọdụ ahụike calcific tendinitis.
2. HA na-abawanye na-emeọkpụkpụ grafting iheyana prosthetics eze na nrụzi. A na-eji HA kpuchie ụfọdụ ihe etinyere, dịka ndochi hip, ihe nkwụnye eze na ihe nrụnye ọkpụkpụ. Dị ka ọnụ ọgụgụ mgbasa nke ala nke hydroxyapatite in-vivo, gburugburu 10 wt% kwa afọ, dị ntakịrị ala karịa mmụba nke ọkpụkpụ ọkpụkpụ ọhụrụ, na-eji ya dị ka ihe na-anọchi ọkpụkpụ, a na-achọ ụzọ iji welie ọnụ ọgụgụ ya solubility na. si otú a kwalite mma bioactivity.
3. Microcrystalline hydroxyapatite (MH) na-ere ahịa dị ka ihe mgbakwunye "ọkpụkpụ na-emepụta ọkpụkpụ" na ntinye dị elu ma e jiri ya tụnyere calcium.
