Essential amino acids: Saraya so amino acids ya agnayarin gawaen na laman na too (odino arum nin vertebrates) ya bukor to odino say synthesis rate to et arawi ed pankaukolan na laman tan kaukolan ya iter na naakan ed paway. Say pankaukolan na essential amino acids parad saray adulto et manga 20% anggad 37% na pankaukolan na protina. Walay 8 a klase, tan saray gagala ra et onia:
Lysine: Makatulong ed itatakken na utek, sakey a kabiangan na altey tan gallbladder, mamaaligwas ed metabolismo na taba, mangireregula ed pineal gland, mammary gland, corpus luteum tan ovary, tan mangaamper ed inkagba na selula;
Tryptophan: Makatulong ed pakawala na gastric juice tan pancreatic juice;
Phenylalanine: Ontutulong ed pangekal na pakaandi na kidney tan pantog;
Methionine: Mibibiang ed komposisyon na hemoglobin, tisyu tan serum, tan walay kimey ton mamaaligwas ed pali, pancreas tan lymph;
Threonine: Walay gagala ton manguman ed pigaran amino acid pian nawalaan na balanse;
Isoleucine: Mibibiang ed regulasyon tan metabolismo na thymus, spleen tan pituitary gland;
Leucine: Manbalanse na isoleucine;
Valine: Onkikiwas ed corpus luteum, mammary gland tan ovary. Semi-essential tan conditionally essential amino acids: Saray amino acid ya sarag ya i-synthesize na laman na too balet ta ag to nasumpal so normal ya pankaukolan et tatawagen ya semi-essential odino conditionally essential amino acids. Saraya so manunan arginine tan histidine, ya importantin amino acid legan na ibabaleg na ugaw. Say pankaukolan na laman na too parad amino acids et onbabawas legan ya ontatakken, tan say pankaukolan na laman na too et onbabawas no ikompara ed saray ugugaw. Saray kimey da et singa onggendan:
Arginine: Say arginine tan deoxycholic acid compound ya preparasyon (minoxline) et epektibon tambal parad syphilis, viral jaundice, tan arum nira.
Histidine: Nayarin usaren bilang biochemical reagent tan pharmaceutical agent, tan nayarin usaren met ed panagtambal na sakit ed puso, anemia, rheumatoid arthritis, tan arum nira.
Non-essential amino acids: Saraya so amino acids ya nayarin gawaen na totoo (odino arum nin vertebrate) manlapud simplin precursors tan agla kaukolan ya naala ed naakan. Saray alimbawa et say glycine tan alanine.
