Nitrilotriacetic acid (NTA) is the aminopolycarboxylic acid with the formula N(CH 2 CO 2 H) 3. It is a colourless solid. It is a colourless solid. Its conjugate base nitrilotriacetate is used as a chelating agent for Ca 2+ , Co 2+ , Cu 2+ , and Fe 3+ .
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. Aminopolycarboxylates that have lost acidic protons form strong complexes with metal ions.

Nitrilotriacetonitrile reacts with methanal at pH 9.5 to give 2,2-dihydroxymethyl-nitrilotriacetonitrile, which is hydrolyzed with sodium hydroxide solution at 100 °C to give the trisodium salt of 2-hydroxymethylserine-N,N-diacetic acid, from which the free acid can be obtained by acidification in 51% yield.

Various carrier matrices bound to a solid resin support are on the market and these can be subsequently charged with a metal cation. Derivatives of iminodiacetic acid (IDA) and nitrilotriacetic acid (NTA) are most frequently used for this purpose, with differing matrices having certain advantages and disadvantages for various applications.

The different types of lipid-linked oligosaccharide (LLO) precursor produced in different organisms.. N-linked glycosylation is the attachment of an oligosaccharide, a carbohydrate consisting of several sugar molecules, sometimes also referred to as glycan, to a nitrogen atom (the amide nitrogen of an asparagine (Asn) residue of a protein), in a process called N-glycosylation, studied in ...
A large fraction of the chemical elements that occur naturally on the Earth's surface are essential to the structure and metabolism of living things. Four of these elements (hydrogen, carbon, nitrogen, and oxygen) are essential to every living thing and collectively make up 99% of the mass of protoplasm. [1]
