Peptides
Peptides play an essential role in
the physiological and biochemical functions of living organisms.
Peptides possess a variety of biochemical activities. They act as
antibiocs, transport metal ions, and function in many other ways.
One of their most significant functions is in regulating biological
functions and transmitting signals throughout the body.
Synthetic peptides have many uses.
Some have pharmaceutical and veterinary applications, either as
drugs or drug candidates. A few peptides are used in cosmetics to
promote repair and healing of the skin. Most synthetic peptides are
used in research though. A few examples of their appliucations include
use to determine the specificity and activity of receptors, to map
epitopes on the surfaces of proteins, and to develop antibodies for
diagnostic or analytical applications.

Pharmaceutical Peptides
Peptides have several properties that
make them attractive drug candidates. They are highly potent, often
very specific, do not accumulate in organs and tissues and have
very few side effects. However, most peptides are readily broken
down by digestive enzymes or are not readily adsorbed through the
intestine so they cannot be administered orally. This has slowed
the development of peptide drugs in the past, but with new methods of
administering peptides such as nasal sprays or long-acting depots,
peptide drugs are receiving new attention.
AAPPTec has over thirty pharmaceutical
peptides availible. To view the list of pharmaceutical peptides from

Cosmetic Peptides
Many skin care products such as lotions and skin creams
include peptides that promote wound healing and repair of damaged skin.
There is evidence that they reduce wrinkles and other effects of aging on the skin.
