Huahana Huahana
ʻO ka Valine (i hoʻopau ʻia ʻo Val a i ʻole V) he ʻakika α-amino me ke ʻano kemika HO2CCH(NH2)CH(CH3)2. ʻO L-Valine kekahi o 20 proteinogenic amino acids. ʻO kona codons ʻo GUU, GUC, GUA, a me GUG. Hoʻokaʻawale ʻia kēia waikawa amino pono ma ke ʻano he nonpolar. ʻO nā kumu meaʻai kanaka he mau meaʻai proteinaceous e like me ka ʻiʻo, nā huahana waiu, nā huahana soy, nā pīni a me nā legumes. Me ka leucine a me ka isoleucine, ʻo valine kahi lālā amino acid. Ua kapa ʻia ma hope o ka mea kanu valerian. I ka maʻi sickle-cell, ua hoʻololi ʻo valine i ka hydrophilic amino acid glutamic acid i ka hemoglobin. No ka mea hydrophobic ka valine, hiki i ka hemoglobin ke hoʻohui like ʻole.
