Lets start with amino acids; these are small molecules that contain
nitrogen group at one end and a carboxyl group at the other end
(COOH); or NH2-C-C00H. There are about 20 different amino acids that
are naturally occuring and they vary in the atoms that are attached
to the middle carbon. These amino acids can become chemically bonded
to each other to form a chain. These bonds are called peptide bonds,
the chain looks like:
NH2 - C - CO - NH -C - COOH
A chain of amino acids will vary in length, large ones are called
proteins, short ones are called peptides. In general a peptide is
defined as being less than 50 amino acids. A protein or peptide is
defined by its sequence of amino acids. For instance, collagen is a
protein and has a distinct sequence of amino acids that is different
from other proteins such as hemoglobin.
In skin care there has been alot of research into stimulating
production (synthesis) of skin structural molecules such as
collagen, elastin or glycosaminoglycans. There are several small
peptides (short chain of amino acids) that have been identified to
have that activity and are sometimes referred to as cosmeceutical
peptides. These can be incorporated into emulsions. They are
expensive, but if they work, WOW. I know Angie sells some so you
could read on her website some specifics about use. This is a very
interesting topic though. I'm going to do a little more reading on
it and write a blog entry on it.
