a metal complex with the EDTA anion Aspartic acid is an aminodicarboxylic acid and precursor to other ligands.. An aminopolycarboxylic acid (sometimes abbreviated APCA) is a chemical compound containing one or more nitrogen atoms connected through carbon atoms to two or more carboxyl groups.
Carboxylic acids are organic acids characterized by a carboxyl (-COOH) functional group. The naming of these compounds is governed by IUPAC nomenclature, which ensures systematic and consistent naming of chemicals. Numerous organic compounds have other common names, often originating in historical source material thereof.
Carbamic acid is a planar molecule. [3]The H 2 N− group of carbamic acid, unlike that of most amines, cannot be protonated to an ammonium group H 3 N + −.The zwitterionic form H 3 N + −COO − is very unstable and promptly decomposes into ammonia and carbon dioxide, [6] yet there is a report of its detection in ices irradiated with high-energy protons.

Many carboxylic acids are produced industrially on a large scale. They are also frequently found in nature. Esters of fatty acids are the main components of lipids and polyamides of aminocarboxylic acids are the main components of proteins. Carboxylic acids are used in the production of polymers, pharmaceuticals, solvents, and food additives.
The double cyanomethylation of β-alanine as starting material provides with methanal and alkali cyanides and subsequent hydrolysis of the intermediately formed bis-methyl cyanides followed by acidification with mineral acids β-ADA (N-(2-carboxyethyl)iminodiacetic acid) in yields of only 80%, but very high purity of 99.8%.
1-Aminocyclopropane-1-carboxylic acid (ACC) is a disubstituted cyclic α-amino acid in which a cyclopropane ring is fused to the C α atom of the amino acid. It is a white solid.
The Schöllkopf method or Schöllkopf Bis-Lactim Amino Acid Synthesis is a method in organic chemistry for the asymmetric synthesis of chiral amino acids. [1] [2] The method was established in 1981 by Ulrich Schöllkopf. [3] [4] [5] In it glycine is a substrate, valine a chiral auxiliary and the reaction taking place an alkylation.
