What Exactly are peptides? what do they Do?

peptides are chains of amino acids. proteins are very large peptides

[Hey Lo]

What Exactly are peptides? what do they Do?

expensive stuff ngl

Basically refer to short chains of amino acids that act like signaling molecules in the body. They’re used to stimulate growth hormone release for muscle and fat loss, speed up healing and recovery, improve skin and hair quality, and even alter things like tanning or muscle growth regulation.

What Exactly are peptides? what do they Do?

Your body breaks down proteins into amino acids, among other things for your body to use for various processes. Peptides are shorter strings of similar amino acids. Because theyre already smaller chains its easier for your body to use them than longer chains broken down from protiens. Theyre more "available," meaning they require less processing to be used. And while they are found in food naturally the can also be used as a supplement. Just as proteins can be supplemented.

There are two types of peptides:

• Endogenous peptides are made by the body. They are naturally released from proteins and secreted from cells in the body.
• Exogenous peptides are manufactured or produced outside of the body by processes, such as enzymatic hydrolysis of proteins, biosynthesis, or organic synthesis.

I am assuming you are talking about drug peptides, though.

The history of peptide drug discovery started by exploiting natural hormones and peptides with well-studied physiological functions for treating diseases caused by hormone deficiencies, such as a lack of insulin required to regulate blood glucose levels in patients with T1DM or T2DM. Diabetes is treated either by insulin injection or by stimulating insulin secretion-related targets such as GLP-1 receptor, to produce insulin GLP-1 receptor agonists, and cardiovascular disease in patients with type 2 diabetes. J. Diabetes Res 2018, 4020492 (2018)." Searching for natural peptides and hormones or replacing them with animal homologues, such as insulin, GLP-1, somatostatin, GnRH, 8-Arg-Vasopressin, and oxytocin, were the initial strategies used for peptide drug discovery and development. However, the drawbacks associated with these natural peptides aroused interest in optimizing their natural sequences, leading to a series of natural hormone-mimetic peptide drugs.

But since your question was vague, ill just list some peptides and their uses.

Hormonal Regulation:

• Insulin: Regulates blood sugar levels.
• Glucagon: Increases blood sugar levels.
• Growth hormone: Stimulates cell growth and repair.
• Oxytocin: Promotes bonding, childbirth, and lactation.
  

Immune Function:

• Defensins: Antimicrobial peptides that fight infections.
• • Cytokines: Signaling molecules that coordinate immune responses.
  • Antibodies: Proteins that neutralize pathogens and toxins.
    

Wound Healing:

• • Growth factors: Stimulate cell proliferation and tissue regeneration.
  • Collagen peptides: Strengthen and repair damaged skin and connective tissues.
  • Angiotensin-converting enzyme (ACE) inhibitors: Reduce inflammation and blood pressure.
    

Muscle Growth and Repair:

• • IGF-1 (Insulin-like growth factor 1): Promotes muscle protein synthesis.
  • BPC-157: Stimulates blood vessel growth and tissue repair.
  • Thymosin beta-4: Enhances immune function and wound healing.
    

Other Functions:

• • Melanocyte-stimulating hormone (MSH): Regulates skin pigmentation.
  • GLP-1 (Glucagon-like peptide-1): Controls appetite and blood sugar levels.
  • Serotonin: Mood regulator and neurotransmitter.
    

Therapeutic Applications:
Peptides are used in a wide range of therapeutic applications, including:

• • Diabetes management: Insulin and glucagon analogs.
  • Cardiovascular health: ACE inhibitors and other peptides that regulate blood pressure.
  • Cancer treatment: Chemotherapy drugs and immunotherapy agents.
  • Wound healing: Growth factors and collagen peptides.
  • Anti-aging therapies: Peptides that stimulate collagen production and reduce wrinkles.
