Me ka inoa o protein ʻIke ʻia nā molecule i haku ʻia o nā amino acid, i hoʻopili ʻia e kekahi ʻano paʻa i ʻike ʻia ʻo nā paʻa peptide. Hana ʻia nā Proteins ma kahi o ka hapalua o ke kaupaona maloʻo o nā kino (a me 20% o ke kaumaha o ke kino o ke kanaka), a ʻaʻohe hana olaola e hoʻopili ʻole iā lākou.

ʻO ke ʻano o kēia mau mole kalapona, hydrogen, oxygen a me nitrogen. ʻO ke kauoha a me ka hoʻonohonoho ʻana o nā amino acid i loko o ka protein e pili ana i ka code genetic o ke kanaka, ʻo ia hoʻi ka DNA.

He aha ka hana a lākou e hoʻokō ai?

He kuleana ko nā protein e pono ai no ka ulu ʻana, a hoʻoikaika nui ʻia ia e ka ʻikepili nitrogen i ʻole i loko o kekahi o nā mole ʻē aʻe i hoʻohui ʻia ma o ka meaʻai: ʻākoʻakoʻa a ʻo ka nā momona.

ʻAʻole like me kēia mau mea ʻelua, ka protein ʻAʻohe o lākou hana mālama ikehu, akā he kuleana nui ko lākou i ka synthesi a me ka mālama ʻana o kekahi mau aʻa a i ʻole nā ​​ʻāpana o ke kino e like me nā wai gastric, hemoglobin, nā wikamina a me kekahi nā ʻenekema. Pēlā nō, kōkua lākou hāpai i nā kinoea like ʻole i loko o ke koko, a hana me he mea hoʻopūʻiwa.

Mawaena o ka hana protein, ma ka ʻaoʻao ʻē aʻe, na lākou e hoʻolako i nā amino acid pono nui no ka synthes kiko, a hana pū kekahi e like me nā mea hoʻoheheʻe olaola hoʻonui i ka wikiwiki o nā hopena kemika o ka metabolism. ʻO ka mea hope loa, hiki ke ʻōlelo ʻia nā proteins e hana me kahi ʻano pale, ʻoiai ʻo nā antibodies he protein pale kūlohelohe i nā maʻi a i ʻole nā ​​ʻākena haole.

E nānā pū: He aha nā mea kumumea?

Waiwai

E pili ana i nā waiwai o nā protein, hiki ke ʻōlelo ʻia ka kūpaʻa ʻO ia ka mea nui loa no ka mea e kūpaʻa nā protein i ke kaiapuni kahi e mālama ʻia ai a i ʻole hoʻomohala i kā lākou hana, i kahi ala e hoʻolōʻihi ai i ko lākou ola ke hiki ke pale i ka hanauna o nā pilikia i loko o ke kino.

Ma ka ʻaoʻao ʻē aʻe, he a mahana a me kahi pH e mālama ai e hōʻoia i ke kūpaʻa, no laila ua ʻōlelo ʻia ʻo ka waiwai waiwai ʻelua ka o ka solubility.

ʻO kekahi mau waiwai ʻē aʻe e like me ʻike kikoʻī, ka pākuʻi pH nalu hiki electrolytic ʻano like pū lākou me kēia papa o nā molaki.

Hoʻokaʻina

Hana ʻia ka hoʻohālikelike maʻamau o nā protein e like me kā lākou hanana kemika, i waena o nā nā polokina maʻalahi hana wale ia i nā amino acid ke hydrolyzed ʻia; ka nā albumins a ʻōpala soluble lākou i ka wai a hoʻoheheʻe i nā hopena; ka glutelins a prolanins soluble i loko ʻakika; ka albuminoids ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai; ka nā protein i hoʻopili ʻia nona nā ʻāpana protein ʻole a proteinnā kūpuna nā huahana o ka hydrolysis.

Ka mea nui i ka papaʻai

ʻO ke kumu nui o ka protein i ke kino kaʻai. ʻO ka mea nui o ka hoʻopili ʻana i nā protein i ka papaʻai he koʻikoʻi koʻikoʻi i nā keiki i ka wā ulu a me nā wahine hāpai, e pono ai ka hana ʻana o nā hunaola hou.

Ke hānai nā kānaka huaʻai mea ʻai a i ʻole ʻiʻo ʻai Hoʻohui lākou i kahi nui o nā protein i loko o ke kaʻina i kapa ʻia ʻo protein digestion, kahi i loko o ka decomposition o ka huahana a hiki i ka hoʻololi ʻana i nā waikawa amino maʻalahi, a laila e hoʻākoakoa iā lākou i mau protein no ke kino, i ke kaʻina i kapa ʻia hoʻohuihui protein. Ma hope wale o kēia ua hoʻohui ʻia i loko o ke kino.

Nā laʻana o nā protein

E nānā pū: Nā laʻana o nā Digestive Enzymes

Nā meaʻai protein kiʻekiʻe

Hiki iā ia ke lawelawe iā ʻoe:

• Nā laʻana o Carbohidrat
• Nā laʻana o Lipids (Fats)
• Nā laʻana o nā Element Trace (a me kā lākou hana)
