Multiple amino acids linked together into a single molecule make up peptides. The chemical interactions between amino acids and peptide bonds keep the proteins together. Proteins are generated from peptides via elaborate steps (usually consisting of 50 or more amino acids). Studies suggest that peptides may serve several functions in the body of research models.
Peptides: Potential Properties
Research suggests that multiple biological processes may rely on peptides. The following are examples of the hypothesized properties of peptides:
- The hypothalamus, a small region near the brain’s base, produces vasopressin (antidiuretic hormone), which is considered a peptide hormone. It has been hypothesized that peptides may control the amount of water that the body may retain. Researchers also speculate that many functions could be attributed to vasopressin.
- It has been proposed that peptides may regulate the amount of water in the medium around cells (extracellular fluid), potentially stimulating the kidneys to remove fluid from the circulatory system. Vasopressin is a vasoconstrictor, meaning it may cause blood vessels to narrow and, in turn, increase blood pressure when generated in significant enough quantities to have an effect.
Peptides and Vasopressin Production
Research suggests the pituitary gland (located in the brain) may produce Oxytocin, a peptide hormone composed of nine amino acids. During labor and delivery, it has been hypothesized to cause the uterus to contract. The reflex of milk evacuation, sometimes known as “put down,” happens during nursing, and Oxytocin is purported to play a crucial role in this process.
Peptides and Defensins
These peptides are thought to be antibacterial and play a significant role in the immune system, which may help to speed up the healing process once a wound has been opened.
Scientists speculate that the peptide hormones known as angiotensins may be involved in blood pressure regulation as part of the renin-angiotensin system. They have been theorized to help maintain healthy blood pressure by stimulating the adrenal glands to produce more aldosterone hormone, encouraging the kidneys to hold onto the salt they have already filtered out of the blood.
Peptides and Antigens
Findings imply that the creation of antigens may rely heavily on peptides. Peptide-based antigens, hypothesized to mimic proteins ordinarily present in pathogens (germs that cause sickness), may allow for duplicating specific immune responses using synthetic antigens.
Peptide-based antigens are speculated to protect against infection by specific pathogens and help in the context of cancer. They have been proposed to induce an anti-tumor T-cell response by immunizing research models with peptides derived from their tumor antigens.
Although peptide-based antigens suggest considerable potential, they are not without their limitations. While developing an effective antigen against Alzheimer’s disease is a goal of the scientific and medical communities, there are significant differences between antigens that employ inactive or weakened viruses and those that use peptides or peptide-based antigens. Antigens based on pathogens could cause a more robust immune response, enhancing their protective efficacy.
Peptides and Collagen
Peptides are hypothesized to be naturally found in foods and supplements, thanks to the many health properties they may have.
Studies suggest that collagen may have anti-aging properties since it is an essential structural protein in connective tissues, including skin, bone, and cartilage. Miniscule collagen shards are known as peptides. Several studies have suggested the potential of collagen peptides for increasing skin elasticity and moisture content in research models. These peptides have been proposed to aid in increasing dermal collagen density.
Collagen is speculated to be used in several wound agents, such as burn damage scaffolds and bandages for burn wounds, because of its potential to hasten healing. An extracellular matrix (ECM) is a three-dimensional network of collagen, enzymes, and other macromolecules surrounding and protecting the body’s cells. Research suggests peptides hypothesized to increase collagen production may mend and heal the skin and increase ECM synthesis (large molecules vital for the body).
Investigations purport that peptides with antimicrobial properties may rejuvenate skin and protect it from infection simultaneously. Findings imply that peptide wound healing may aid research subjects with impaired healing functions, including the portion of the diabetic research models that has non-healing injuries and wounds. Scientists and academics interested in learning more about peptides may find peptides for sale to conduct more studies on the topic.
