Research Peptides find its extensive use in a number of applications in the molecular biology due to many reasons. Peptides allow the creation of peptide antibodies without undergoing purification within an animal’s body. Moreover, research peptide also allows identifying proteins under study in mass spectroscopy on peptide sequence. The structure and functions of protein structure can be identified by these research proteins. The American Science Labs also conducts various peptide studies based upon research proteins to perform animal studies.

Peptides, with its origin from the Greek word, are chemical compounds of polymers of amino acids. They are covalently linked by peptide bonds, with reactions of the amine group of amino acid and the carboxyl group of another. Peptides differ from proteins on the basis of size, the number of amino acids joined together in their structure. Research peptides fall into various classes according to which they are formed. Milk proteins, derived from casein, the healthy protein found in milk, is formed by fermentation or digestion of enzymes.
Ribosomal peptides, on the other hand, are the result of transcription and translation of nucleic acids, mRNA which is catalyzed by various proteolytic enzymes. They are hormones of the higher organism, performing a wide range of functions in their body. Nonribosomal peptides, for example, Glutathione, is the commonly found one, in most anaerobic organisms to create antioxidant defenses. Peptones, obtained from animal meat and milk are fragmented by proteolytic enzymes. They are widely used by the laboratories as a nutrient media for fungi and bacterial growth. The nutrient culture exhibits many properties due to its widespread use in fungal growth.
Many naturally occurring peptides possess a wide array of functions such as hormones, neurotransmitters, and antibiotics. For example, the modern research peptide Atrial natriuretic peptide which maintains a balance of blood pressure in the body by retaining water, sodium and adipose loads on the circulatory system. Peptide hormone in conjunction with protein receptor of the target cell, triggers receptor, making it permeable into the cell interiors. Strangely, some peptides are even implicated in modulating emotions. The neurotransmitters play an important role in serving the duties of transmitters.
Food-derived peptides, otherwise, bioactive peptides are another area of interests. They have diverse biological activities which are shared from in-vitro data, but this only has limited clinical evidence to justify the development of them. Hydrolysates which are peptide molecules also put forth to study its use widely as neutraceuticals and functional foods promoting health. Studies are also being made on Antimicrobial peptides, which act as a natural defense against bacteria, fungal and viral strains. They are found to kill target organism within the cells, enhance the drug resistant property to a larger extent.
Additionally, their applications in the area of the food industry, to create a mutant strain resistant to diseases, cultivation of transgenic bio-organisms and aquaculture are still the patented projects under investigation. Hence, research peptides give broad spectra of information which are applicable to various fields of utility in the scientific world.
