Kuyambitsa kwa Amino Ads

Kodi amino acid ndi chiyani?
Ma amino acid omwe ali m'chilengedwe amatchedwa α-amino acid. Izi mamolekyulu ali ndi mitundu inayi yolumikizidwa ndi malo ophatikizika a carbon atomu (yotchedwa α-C):
Amino (NHE₂, makalata atatu ofupikitsidwa ngati "h-").
Carboxtylic acid Gulu (Cooh, adaduleni ngati "--Oh" mu nambala itatu).
Maunyolo(R, zomwe zimasinthika kwambiri ndikuzindikira zomwe Amakonda komanso peptide komaliza).
Hydrogen atomu (H).
Kulumikizana kwa ma atomu a α

Ntchito zachilengedwe za amino acids
Amino Acids imatha kuwonetsa zochitika zachilengedwe monga:
Tryptophan (trp) ndi glutamic acid (glu) amatenga mbali yofunika kwambiri pakupanga metabolic.
Gulu la R gulu (kapena mbali ya mbali) limafotokoza zomwe amapeza za amino acid. Magulu awa amatha:
M'mawu osavuta:Atom hydrogen ngati glycine (gly).
Acid ena amaphatikizidwa: monga aspartic acid (asp) ndi glutamic acid (glu).
Kunyamula magulu oyambira:Arlinine (arg), lysine (LYS) kapena Ristadine (Wake).
Muli magulu a polar: monga Serine (Ser) kapena chisokonezo).
Ma hydrocarbons:Alanine (Ala), phenylalanine (phesi) kapena ma vanine (Val).
Sulfur Zokhudza:Monga taonera mu Cysteine ​​(CYYS) ndi Methionine (adakumana).
Udindo wa L-amino acids ndi d-amino acid
Mitundu inayi ya atomu ya α-C yakonzedwa m'makona a tetravedron, yokhala ndi α-c atomu pakati (onani Chithunzi 3). Dongosolo ili limalola mitundu iwiri ya amino acid kuti akhale pagalasi lagalasi, ofanana ndi manja a kumanzere ndi manja. Mafomu agalasi awa amadziwika kuti "stereaoomers" kapena "othandizira".
Kufunikira kwachilengedwe kwa reantiomers
Ngakhale othandizira ali ndi vuto lofanana ndi thupi, zinthu zomwe zimachitika zachilengedwe zimatha kusiyanasiyana. Mawonekedwe a molecular ndi ofunikira kwambiri kuti azigwirizana ndi zomwe zikuchitika zachilengedwe. Winantiomer wina akhoza kumangirira bwino ku chandamale, wina sangatero, kapena nthawi zina amakhala ndi vuto. Mu njira, anintioteri amazungulira ndege yowala yowala mbali inayo.
