Carboxyl group or carboxyl group –COOH or CO2H is a functional group present in amino acids and carboxylic acids. In Organic chemistry, functional groups are specific groups of Atoms within Molecules that are responsible for the characteristic Chemical reactions Carbon (kɑɹbən is a Chemical element with the symbol C and its Atomic number is 6 Oxygen (from the Greek roots ὀξύς (oxys (acid literally "sharp" from the taste of acids and -γενής (-genēs (producer literally begetteris the Oxygen (from the Greek roots ὀξύς (oxys (acid literally "sharp" from the taste of acids and -γενής (-genēs (producer literally begetteris the Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 In Organic chemistry, functional groups are specific groups of Atoms within Molecules that are responsible for the characteristic Chemical reactions In Chemistry, an amino acid is a Molecule containing both Amine and Carboxyl Functional groups In Biochemistry, this Carboxylic acids are Organic acids characterized by the presence of a Carboxyl group, which has the formula -C(=OOH usually written -COOH or -CO2H Its structure is composed of one carbon atom attached to an oxygen atom by a double bond and to a hydroxyl group by a single bond. Hydroxyl in Chemistry stands for a molecule consisting of an Oxygen atom and a Hydrogen atom connected by a Covalent bond. It is often mentioned that a carboxyl group is a carbonyl group bonded to a hydroxyl group. In Organic chemistry, a carbonyl group is a Functional group composed of a Carbon Atom double-bonded to an Oxygen Hydroxyl in Chemistry stands for a molecule consisting of an Oxygen atom and a Hydrogen atom connected by a Covalent bond. The carboxyl group has one valence electron in its carbon atom, making it possible to be a part in a larger molecule by bonding through it. In chemistry valence electrons are the Electrons contained in the outermost or valence, Electron shell of an Atom. In Chemistry, a molecule is defined as a sufficiently stable electrically neutral group of at least two Atoms in a definite arrangement held together by Carboxyl groups can only occur at the end of a carbon chain, because the carbon must make 3 bonds (O double bond and single bond to hydroxyl group) in addition to its connection to the R group.
Carboxyl groups will often lend their H+ into solution and therefore will act as acids. This is the case with carboxylic acids, such as is the case when acetate lends its H+ into solution to become acetic acid. An acetate, or ethanoate, is either a salt or Ester of Acetic acid. Acetic acid, also known as ethanoic acid, is an organic chemical compound, giving Vinegar its sour taste
