where are amino groups found?
449713
The amino group is one of several nitrogen-containing functional groups found in organic molecules.
420952
Ionizable Amino Acids. Seven out of the twenty amino acids contain readily ionizable side chain groups. That means that at specific pH values, each side chain can participate in an acid-base reaction in which it can exchange a hydrogen atom with some other biomolecule.
104934
Both the amino group and the carboxyl group of each amino acid are ionizable. The carboxyl group (with a pKa of about 3) is deprotonated at physiological pH. The amino group is protonated at physiological pH. ... In addition, the side chains of some of the amino acids contain ionizable groups.

An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.

Hydrophobic Amino Acids Amino acids are grouped according to what their side chains are like. The nine amino acids that have hydrophobic side chains are glycine (Gly), alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile), proline (Pro), phenylalanine (Phe), methionine (Met), and tryptophan (Trp).

Hydrophobic amino acids are those with side-chains that do not like to reside in an aqueous (i.e. water) environment. For this reason, one generally finds these amino acids buried within the hydrophobic core of the protein, or within the lipid portion of the membrane.

Amino acid chart. There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. ... They can be subdivided according to their properties, dictated by the functional groups they possess.
677398
Amino acids are organic compounds that contain amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid.
509055
Each of the 20 amino acids has a specific side chain, known as an R group, that is also attached to the α carbon. The R groups have a variety of shapes, sizes, charges, and reactivities. This allows amino acids to be grouped according to the chemical properties of their side chains.

An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. The term amino acid is short for α-amino [alpha-amino] carboxylic acid. ... Amino acids function as the building blocks of proteins.

amino group, in chemistry, functional group that consists of a nitrogen atom attached by single bonds to hydrogen atoms, alkyl groups , aryl groups , or a combination of these three. An organic compound that contains an amino group is called an amine. Amines are derivatives of the inorganic compound ammonia , NH 3.
917569
The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N), although other elements are found in the side chains of certain amino acids.

Terms in this set (48) Amino acid Definition: An amino acid is a carboxylic acid with an amino group and the building block of proteins. ... contains 2 or more NH2 groups or nitrogen atoms (base ).
304401
Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains.
840636
The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N), although other elements are found in the side chains of certain amino acids. ... In the form of proteins, amino acid residues form the second-largest component (water is the largest) of human muscles and other tissues.

Amino group The amino nitrogen at atom 1 has three hydrogens attached. The backbone of each amino acid starts with the same collection of atoms, but changes occur as peptide bonds are formed. The amino group starts out as a nitrogen atom bonded to three hydrogen atoms.

Introduction. Amino acids are a class of important biomolecules that contain both amino groups and carboxylate groups (–COO−). In most contexts, the term 'amino acids' refers to the α-amino acids, so-called because both the amino and carboxyl groups are attached to the α-carbon of the structure depicted in Figure 1(a).
