He aha ka Peptide？

ʻO nā peptide nā pūhui i hoʻohui ʻia ʻelua a ʻoi aku ʻelua mau waikawa amino e nā paʻa peptide.He waiwai waena lākou ma waena o nā amino acids a me ka protein, a me ka meaʻai a me ka waiwai kumu o nā cell a me ke ola.

Mai ka loaʻa ʻana o ka protein i ka makahiki 1838, a hiki i ka ʻike mua ʻana o ka polypeptide i loko o ke kino o ke kanaka e ʻelua physiologists Bayliss a me Starling ma ke Kulanui o London School of Medicine ma 1902. Ua ʻike ʻia nā peptide ma mua o hoʻokahi haneli.

Lawe ʻia ka peptide collagen iʻa hohonu mai loko mai o ka iʻa kai me ka haumia manuahi.ʻOi aku ka maikaʻi o kona kūpaʻa ma mua o ka mole kolagen maʻamau.Me nā hiʻohiʻona o ka ʻoi aku o ka wela, ka waika a me ke kūpaʻa alkali, a me ke kūʻē ʻana i ka denaturation, hiki ke hoʻopili pololei ʻia e ke kino kanaka me ka ʻole o ka ʻeli ʻana a me ka haku ʻana ma o ka ʻōpū o ka ʻōpū.He aha'ʻOi aku ka maikaʻi o ka hōʻemi ʻana i ke kaumaha metabolic o nā puʻupaʻa a hāʻawi i ke kino o ke kanaka me ka ʻoi aku ka maikaʻi a me ka maʻalahi o ka lawe ʻana i ka protein kiʻekiʻe.

Hiki i ka peptide haʻahaʻa iʻa iʻa ke hana i ka calcium i hui pū ʻia me nā pūnaewele iwi, me ka ʻole o ka poho a me ka degeneration.

Hiki i ka peptide iʻa hohonu ke hoʻoikaika i ka absorption o ka calcium, he mea koʻikoʻi ka ʻōnaehana o ka collagen no ka mālama pono ʻana i ka ʻano iwi a me nā waiwai biomechanical iwi.Hiki i nā polypeptides i loko o ka collagen ke pale i ka hoʻokumu ʻana o nā stains ma o ka noho ʻana i ka hana o tyrosinase.
