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 ).
432677
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.

Medical Definition of Amino acid symbols. Amino acid symbols: Symbols that stand for the amino acids, the building blocks of protein. Each amino acid has both a three-letter symbol and a single-letter symbol. For example, the three-letter and single-letter symbols for alanine are Ala and A.
880687
Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure , which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
794137
A peptide bond forms between the carboxylic acid of one amino acid and the amino group of the next amino acid. ... Composed of molecular building blocks called amino acids. If more than 50 amino acids are in the peptide chain that has biological activity, it is a protein.
356471
Amino acids are organic compounds that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left.
1004190
Codons are nitrogen bases that are aligned to create amino acids, and it is these amino acids that form proteins through peptide bonds (DiscoveryEducation).
380476
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. The simplest, and smallest, amino acid is glycine for which the R-group is a hydrogen (H).
470940
Amino acids are the basic structural units of proteins. An amino acid consists of an amine group, carboxyl group, hydrogen atom, and a side-chain group, all bonded to a central carbon atom. Amino acids are classified according to the solubility properties and ionizability which they derive from their side-chains.
868115
All amino acids have the alpha carbon bonded to a hydrogen atom, carboxyl group, and amino group. The "R" group varies among amino acids and determines the differences between these protein monomers.
569162
Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—are not synthesized by mammals and are therefore dietarily essential or indispensable nutrients. These are commonly called the essential amino acids.
36885
The 9 essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. (It's worth noting there is a debate raging in protein science around whether the correct number is 8 or 9 essential amino acids.
578287
There are twenty kinds of amino acids that support the body, each having their own functions. There are as many as one hundred thousand kinds of proteins that constitute the body, and these comprise only twenty kinds of amino acids in various combinations. These twenty amino acids are essential to the body.

They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur. Each amino acid contains a carboxylic acid end and an amino end.

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.

Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the α carbon. Each of the 20 amino acids has a specific side chain, known as an R group, that is also attached to the α carbon.
