Difference between things.....
 

Just like rocks we are all structured
under the laws of phyiscs and chemistry,yet we are alive and rocks are not........A science project was handed out to me to actually fine out more about these statement if rocks do live in such a way that we do not know......
But to my knowledge i'm not even sure if i could answer corretly but i do belive that they are alive.....Yet i will need all the help i can get to take a better presentation to school and to advance more to a +A.....Please these question has not been answered by any1 i've asked.....HELP...........

In science, peptide synthesis is characterized as the formation of a peptide bond between two amino acids. While the definition of a peptide is not definitive, it usually refers to flexible (little secondary structure) chains of up to 30-50 amino acids. United Peptide ( unitedpeptide.com ) provide peptide synthesis services.

The ability to form peptide bonds to link amino acids together is over 100 years old, although the first peptides to be synthesized, including oxytocin and insulin, did not occur for another 50-60 years, demonstrating the difficult task of chemically synthesizing chains of amino acids (1). In the last 50 years, advances in protein synthesis chemistry and methods have developed to the point where peptide synthesis today is a common approach in even high-throughput biological research and product and drug development (2).

The benefit of peptide synthesis strategies today is that besides having the ability to make peptides that are found in biological specimens, creativity and imagination can be tapped to generate unique peptides to optimize a desired biological response or other result. This page highlights the important aspects of peptide synthesis, the most common methods of synthesis and purification and the strengths and limitations of the respective strategies.
