Functional group is a part of an organic molecule which takes a part in chemical reaction for example in alcohols functional group is -OH , in carboxylic acids is -COOH and so on, but formaldehyde CH2O is a molecule and it is completely a functional group.
If you mean the hydroxyl functional group (-OH), then only serine and threonine contain it. However, all amino acids contain one or more carboxylic acid (-COOH) functional groups and they all contain OH as part of that functional group, though the carboxylic acid functional group should be considered a single unit.
It should be obvious from the name that one of the functional groups (three of them, in fact) is a nitro group, NO2. Somewhat less obvious is that there's also a methyl group and a benzene ring that make up the "toluene" part of the name.
carboxyl group of an amino acidf.franklin.....
Mainly The R Group, but also that there is also the particular positions that give the amino acid molecule its characteristic chemical properties. Another is at the -C-C-N- peptide linkage.
the carboxyl functional group
An acidic acid is something with a pH of less than 7.0. Actually this term is used for Amino acids having carboxylic groups higher than amino groups.
Functional group is a part of an organic molecule which takes a part in chemical reaction for example in alcohols functional group is -OH , in carboxylic acids is -COOH and so on, but formaldehyde CH2O is a molecule and it is completely a functional group.
Amino acids have both amine and carboxylic acid functional groups and are therefore both an acid and a base at the same time.
If you mean the hydroxyl functional group (-OH), then only serine and threonine contain it. However, all amino acids contain one or more carboxylic acid (-COOH) functional groups and they all contain OH as part of that functional group, though the carboxylic acid functional group should be considered a single unit.
Amino acids are of different types e.g. acidic,basic,neutral, imino ,and sulpher containing etc but all types of amino acids possess two functional groups. These functional groups are amino group and carboxylicgroup. An amino group is chemically NH2 , it is a basic group. Other functional group is carboxylic group which is chemically COOH , it is acidic in nature, Functional group is part of molecule that gives it ,its specific chemical characters.Presence of these groups makes amino acid amphoteric.
A functional group may react differently, but does not always do so. One of the well known examples is a hydroxyl group, which ionizes sufficiently to act as a weak acid when the hydroxyl group is bonded directly to a carbon atom that is part of an aromatic ring, but not when the hydroxyl group is attached to a carbon that is part of an aliphatic chain.
a carboxylic acid and an amine group combine to form nylon which is a condensated polymer
An amino acid and an anticodon. (APEX)
I wouldn't call them side chains, a term which refers to part of a branching carbon skeleton. The two functional groups involved in bonding are the carboxylic acid group, -COOH and the amino group, -NH2.
Carbonic acid is the name of the compound H2C03.
It is an amino group, part of the structure of an amino acid that also includes alpha carbon, carboxyl group, hydrogen and an R group side chain. Basic amino group H2N (-NH2) may gain a proton and become -NH3+, an acidic carboxyl group (H3N).
