1. Kupezeka kwa amino acid
Kupezeka kwa amino acid kunayamba ku France mu 1806, pomwe akatswiri amisili Louis Nicolas Vauquelin ndi Pierre Jean Robiquet adasiyanitsa kompositi ndi katsitsumzukwa (kenaka kadzatchedwa asparagine), amino acid woyamba adapezeka. Ndipo kupezeka kumeneku kudadzutsa chidwi cha asayansi pazinthu zonse zamoyo, ndikupangitsa anthu kufunafuna ma amino acid ena.
M'zaka makumi angapo zotsatira, asayansi adapeza cystine (1810) ndi monomeric cysteine ​​(1884) mu miyala ya impso. Mu 1820, akatswiri azamankhwala adatulutsa leucine (chimodzi mwazinthu zofunika kwambiri za amino acid) ndi glycine kuchokera minofu ya mnofu. Chifukwa cha kupezeka kwa minofu, leucine, pamodzi ndi valine ndi isoleucine, amadziwika kuti ndi amino acid wofunikira pakupanga mapuloteni am'mimba. Pofika 1935, ma 20 amino acid onse adapezeka ndikuwerengedwa, zomwe zidapangitsa kuti a William Cumming Rose (William Cumming Rose) azindikire zomwe amafunikira tsiku ndi tsiku. Kuyambira pamenepo, ma amino acid ndi omwe akhala akugwiritsidwa ntchito ndi makampani azolimbitsa thupi omwe akukula mwachangu.

2. Kufunika kwa amino acid
Amino acid amatanthauza chophatikiza chomwe chimakhala ndi gulu la amino komanso gulu la acidic carboxyl, ndipo limatanthawuza gawo lomwe limapanga mapuloteni. M'chilengedwe, ma amino acid omwe amapanga mapuloteni achilengedwe ali ndi mawonekedwe ake.
Mwachidule, amino zidulo ndizofunikira pamoyo wamunthu. Tikangoyang'ana pa hypertrophy ya minofu, kupindula mphamvu, kuchita masewera olimbitsa thupi, komanso kuchita masewera olimbitsa thupi komanso kuchira, titha kuwona zabwino zama amino acid. M'zaka makumi angapo zapitazi, asayansi ya zamoyo atha kusanja molondola kapangidwe ndi kuchuluka kwa mankhwala m'thupi la munthu, kuphatikiza 60% madzi, 20% mapuloteni (amino acid), 15% mafuta ndi 5% chakudya ndi zina. Chofunikira cha amino acid kwa akulu ndi pafupifupi 20% mpaka 37% yofunikira ya protein.

3. Chiyembekezo cha amino acid
M'tsogolomu, ofufuza apitiliza kuvumbula zinsinsi za zinthu zamoyozi kuti awone kuti akukhudzidwa ndi zochitika zonse zokhudzana ndi thupi la munthu.
