Peptides are ideal cosmetic ingredients
Peptides are ideal cosmetic ingredients that can be used to counteract wrinkles formation and loss of elasticity. Using advance technology and peptide synthesis techniques, Bio-Synthesis can manufacture research and GMP grade cosmetic peptides to your specifications. Most popular cosmetic peptides are palmitoyl hexapeptide, palmitoyl tetrapeptide, palmitoyl pentapeptide.

Beauty meets Science
Imagine a world where youthfulness surrounds us, when young skin is no longer a fad but a way of life and it’s as easy to achieve as going to the grocery store. We may soon be heading in that direction. In this day and age, science is being incorporated into every part of our life, and beauty is no different. Thanks to a chain of amino-acids called peptides, looking young is possible for any woman of any age.
Peptides are defined as smaller chains of proteins made of Amino acids. These shortened forms of proteins aid our skin in its ability to function. Considering that twenty-five percent of our skin is comprised of proteins, is it any wonder that peptides are so useful?
There are three leading peptides in this beauty revolution, according to CellularSkin Rx, a website dedicated to the science behind skin, Argireline, Palmitoyl Oligopeptide, and Palmitoyl Tetrapeptide-3. Each peptide has its own separate but highly effective function to help not only repair skin, but also keep its youthful glow.
Argireline helps to relax facial muscles, and reduce the appearance of fine lines and wrinkles. It works almost like a topical botox.
The second primary peptide Palmitoyl Oligopeptides stimulates elastin, collagen, and connective tissues to help make the skin tighter and tauter. Palmitoyl Oligopeptides also enables moisturization of the skin (a main component for younger looking skin).
The last of the three primary peptides Palmitoyl Tetrapeptide-3, not only reverses some of the sun’s damage but also speeds up the healing process of our skin to allow us more youthful looking skin at a much quicker speed.
Many beauty companies are now beginning to combine these peptides to make “end all” beauty products that allow youthful looking skin from all fronts. Women can say goodbye to painful Microdermabrasion, and laser treatments. These new beauty weapons are quickly making headway in the industry.
As technology and research advance, peptide enriched beauty products will allow women to shed decades off their look in a safe and affordable manner.

Protein Biosynthesis
Protein Biosynthesis (synthesis) is the process in which cells build proteins. The term is sometimes used to refer only to protein translation but more often it refers to a multi-step process, beginning with amino acid synthesis and transcription which are then used for translation. Protein biosynthesis, although very similar, differs between prokaryotes and eukaryotes.
Amino acid synthesis
Amino acids are the monomers which are polymerized to produce proteins. Amino acid synthesis is the set of biochemical processes (metabolic pathways) which build the amino acids from carbon sources like glucose. Not all amino acids may be synthesised by every organism, for example adult humans have to obtain 8 of the 20 amino acids from their diet.
Transcription
Transcription is the process by which an mRNA template, encoding the sequence of the protein in the form of a trinucleotide code, is transcribed from the genome to provide a template for translation. Transcription copies the template from one strand of the DNA double helix, called the template strand.Transcription can be divided into 3 stages: Initiation, Elongation and Termination, each regulated by a large number of proteins such as transcription factors and coactivators that ensure the correct gene is transcribed in response to appropriate signals.The DNA strand is read in the 3' to 5' direction and the mRNA is transcribed in the 5' to 3' direction by the RNA polymerase.
Translation
The synthesis of proteins is known as translation. Translation occurs in the cytoplasm where the ribosomes are located. Ribosomes are made of a small and large subunit which surrounds the mRNA. In translation, messenger RNA (mRNA) is decoded to produce a specific polypeptide according to the rules specified by the genetic code. This uses an mRNA sequence as a template to guide the synthesis of a chain of amino acids that form a protein. Translation is necessarily preceded by transcription. Translation proceeds in four phases: activation, initiation, elongation and termination (all describing the growth of the amino acid chain, or polypeptide that is the product of translation).In activation, the correct amino acid (AA) is joined to the correct transfer RNA (tRNA). While this is not technically a step in translation, it is required for translation to proceed. The AA is joined by its carboxyl group to the 3' OH of the tRNA by an ester bond.
