1.Qhov pom ntawm cov amino acids
Kev tshawb pom cov amino acids tau pib hauv Fabkis xyoo 1806, thaum cov kws kho mob Louis Nicolas Vauquelin thiab Pierre Jean Robiquet sib cais cov khoom sib xyaw los ntawm asparagus (tom qab paub tias yog asparagine), thawj cov amino acid tau pom. Thiab qhov kev tshawb pom tam sim ntawd tau txhawb kom cov zej zog tshawb fawb txaus siab rau tag nrho lub neej kev tiv thaiv, thiab ua rau tib neeg tshawb nrhiav lwm cov amino acids.
Hauv ob peb xyoos tom ntej no, cov kws tshawb fawb pom cystine (1810) thiab monomeric cysteine ​​(1884) hauv cov pob zeb pob zeb. Xyoo 1820, cov kws tshuaj rho tawm leucine (ib qho tseem ceeb tshaj plaws cov amino acids) thiab glycine los ntawm cov leeg nqaij. Vim tias qhov kev tshawb pom no hauv cov leeg nqaij, leucine, nrog rau valine thiab isoleucine, tau txiav txim siab tias yog ib qho amino acid tseem ceeb rau kev tsim cov protein protein. Los ntawm 1935, tag nrho 20 cov amino acids sib xyaw tau tshawb pom thiab cais tawm, uas ua rau tus kws tshuaj lom neeg thiab kws noj zaub mov William Cumming Rose (William Cumming Rose) ua tiav txiav txim siab yam tsawg kawg nkaus txhua hnub cov amino acid xav tau. Txij thaum ntawd los, cov amino acids tau dhau los ua qhov tseem ceeb ntawm kev lag luam qoj ib ce muaj zog.

2. Qhov tseem ceeb ntawm cov amino acids
Amino acid nthuav dav hais txog cov organic sib xyaw uas muaj ob qho yooj yim amino pab pawg thiab cov kua qaub carboxyl pab pawg, thiab hais txog cov txheej txheem uas tsim cov protein. Hauv ntiaj teb kev lom neeg, cov amino acids uas tsim cov protein ntuj muaj lawv cov yam ntxwv tshwj xeeb.
Hauv ntej, amino acids yog qhov tseem ceeb rau tib neeg lub neej. Thaum peb tsuas yog tsom mus rau cov leeg nqaij hypertrophy, nce lub zog, ua kom muaj kev tswj hwm, thiab ua kom lub cev qoj ib ce thiab rov zoo, peb tuaj yeem pom cov txiaj ntsig ntawm cov amino acids. Hauv ob peb xyoos dhau los, cov kws tshawb fawb biochemists tau tuaj yeem cais cov qauv thiab feem ntawm cov sib xyaw hauv tib neeg lub cev, suav nrog 60% dej, 20% protein (amino acids), 15% rog thiab 5% carbohydrates thiab lwm yam khoom. Qhov xav tau ntawm cov amino acids tseem ceeb rau cov neeg laus yog kwv yees li 20% txog 37% ntawm qhov xav tau ntawm cov protein.

3. Lub zeem muag ntawm cov amino acids
Yav tom ntej, cov kws tshawb fawb tseem yuav nthuav qhia qhov paub tsis meej ntawm cov khoom siv hauv lub neej no los txiav txim siab tias lawv tau koom nrog txhua qhov txheej txheem cuam tshuam nrog tib neeg lub cev.
