Phenylalanine zwitterion
Web페닐알라닌(영어: phenylalanine) (기호: Phe or F) 은 단백질의 생합성에 사용되는 α-아미노산이다. 페닐알라닌은 α-아미노기(생물학적 조건에서 양성자화된 −NH 3 + 형태), α-카복실기(생물학적 조건에서 탈양성자화된 −COO − 형태) 및 곁사슬인 벤질기를 포함하고 있다.페닐알라닌은 곁사슬인 벤질기의 ... Phenylalanine (symbol Phe or F) is an essential α-amino acid with the formula C 9H 11NO 2. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The L-isomer is used to bioche…

WebBetaine is a permanent zwitterion. The molecular betaine anion has been generated in a hybrid, infrared desorption-electron photoemission source and its photoelectron spectrum recorded. The photoelectron spectrum of the betaine anion is characteristic of a dipole bound anion, and its vertical detachment energy was measured to be 0.29±0.03 eV. WebA zwitterion is a molecule with functional groups, of which at least one has a positive and one has a negative electrical charge. The net charge of the entire molecule is zero. Amino acids are the best-known examples of zwitterions. They contain an amine group (basic) and a carboxylic group (acidic).
