Alanine is an amino
acid.
Amino acids generally are defined in the column on the right. There
are two types of amino acid:
* Those that can be synthesized by
the body
itself, and
*
Those
that
(are necessary
for
healthy
growth
or maintenance
of the body) but cannot be produced by the body itself. This second
type of amino acids are called "Essential
Amino Acids", and are also referred to as "Indispensible Amino
Acids" in some textbooks.
Alanine is a "non-essential" or "dispensible" amino
acid because, although its presence in an appropriate quantity is important
for good health, the human body can produce this chemical (from any excess
of certain other amino acids in the body). Therefore it is not essential
as a component of one's diet.
Alanine is important for
the healthy functioning of the liver. It also plays an important role
in the management of energy provision to muscle tissues: When
there is a need for energy but a deficit of oxygen in tissues,
muscle
proteins are broken down for energy. Alanine then
acts as a carrier
molecule
to transport the nitrogen-containing amino group to the liver to
be changed into the less toxic urea. This helps to prevent accumulation
of toxic substances in
muscle cells.
The molecular formula of alanine is: C3H7NO2

Amino Acids
Amino acids are important biological units sometimes called the "building
blocks" of proteins because many amino
acids together form proteins. Proteins, form much of
the structure
of cells, and cells are
the basic functional units of living organisms.
Chemistry of Amino Acids:
Amino acids are organic compounds that include both an amino group,
and a carboxyl group:
The term "organic
compound"
refers to substances whose molecular structure is based on the
presence and properties of the element carbon (chemical symbol: "C").
An "amino group" is
a group of atoms arranged in a particular configuration that
includes the elements nitrogen and hydrogen and is represented by
(-NH2).
A "carboxyl group" is
a group of atoms arranged in a particular configuration that
includes carbon, oxygen, and hydrogen and is represented by (-COOH). |
