of Synthetic Peptides: Synthetic peptides are widely
used for the following purposes: - To verify the structure
of naturally occurring peptides as determined by degradation
techniques - To study the relationship between structure
and activity of biologically active protein and peptides
and establish their molecular mechanisms - To develop
new peptide-based immunogens, hormones, vaccines, etc
Peptide Drugs: Peptide drugs are either naturally-occurring
peptides or altered natural peptides. There are many
naturally-occurring peptides that are biologically active.
If a patient does not naturally produce a peptide that
they need, this peptide can be synthesized and given
to them. In addition, the amino acids in an active peptide
can be altered to make analogues of the original peptide.
If the analogue is more biochemical active than the
original peptide it is known as an agonist and if it
has the reverse effect is known as an antagonist. Diagnostic
Peptides: Peptides can be designed that change color
under certain conditions, and these can be used for
diagnostic purposes. For example, a chromogenic peptide
substrate can readily detect the presence, absence and
varying blood levels of enzymes that control blood pressure
and blood clotting ability.
Local: Peptide
is the members of the compounds composed of two or more amino acids joined by
the linking between one amino acid residue and the carboxyl group of the next amino acid
by hydrolysis into linear,
branched or cyclical structures. The link is an amide bond, and is sometimes referred to as a peptide bond.
Peptides are playing a promising role in the molecular biology
and in the creating medicines. Peptides are used in the study
of protein structure and
function, antibodies for the inhibition of cancer, for the study of protein structure and
function research. Peptides are also used as instrumental in mass spectrometry.
Biological activities of peptide are applicable
in the fields of nutrition, medicine, and
cosmetics.
- Dipeptide:
a molecule consisting of two amino acids
- Tripeptide a molecule consisting of three amino acids
- Octapeptide:
a molecule consisting of eight amino acids
- Oligopeptide:
a polypeptide
composed of approximately
2-12 amino acids length (or 3 to 40 component amino acids)
- Polypeptide:
a
single molecule composed of approximately 13 or more amino
acids.
- Protein:
a linear polypeptides that are normally synthesized on
ribosomes.
