Peptide is a small molecular structure of protein, peptide is the condensation of one amino acid and another amino acid to form titanium. Amino acids are called peptide bonds in the chemistry of proteins, the molecules of amino acids are small and the molecules of proteins are large, two and more amino acids dehydrate and condense to form peptides, one peptide and the other peptides carry out the overlap of multiple groups to form protein molecules. Protein is sometimes called polypeptide, as the name suggests, polypeptide is actually several proteins, several amino acids connected to form a functional structure, it can be divided into antihypertensive peptide, antioxidant peptide, cholesterol peptide, etc. from function. So, peptide is the name of protein small molecule, and the smallest structure of protein is amino acid.

Functions of Peptide

Pressor hormone

This is a peptide hormone secreted in the hypothalamus (a small part of the brain located at the base of the brain) Pressor hormone has several functions.

It is responsible for regulating the amount of water present in the fluid space around the cells (extracellular fluid), and it does this by causing the kidneys to absorb water. Heavy use of pressin is also a vasoconstrictor, which means it causes blood vessels to narrow, which leads to an increase in blood pressure. Vasopressin is inhibited by alcohol consumption, which can cause people to urinate more than usual.


This peptide hormone is produced by the pituitary gland (located in the brain) and is made up of nine amino acids. It causes the uterus to contract during labor. Oxytocin also plays a key role in the lactation reflex ("milk let-down") during breastfeeding. Oxytocin is sometimes called the "cuddle hormone" or "love hormone" because it is released when people snuggle together or socialize.


These peptides are active mainly in the immune system and are thought to have antimicrobial effects, thus promoting the wound healing process. 

Angiotensin: These peptide hormones are part of the renin-angiotensin system. They help to regulate blood pressure and stimulate the release of aldosterone from the adrenal cortex, thus promoting sodium retention in the kidneys.

Peptide Uses and Benefits

Peptide Uses and Benefits

Collagen is a protein found in the skin, hair and nails. Collagen peptides are broken down collagen that is more easily absorbed by the body.

  • Prevention of age-related bone loss

Trusted sources of animal studies have linked moderate intake of collagen peptides to increased bone mass in growing rats that also performed running exercises.

This study may point to collagen peptides as a useful way to combat age-related bone loss. However, more research is needed, especially in humans.

  • Enhanced strength and muscle mass

Several studies with credible sources on older adults have shown that collagen peptide supplements can increase muscle mass and strength. In this study, participants combined the use of supplements with resistance training.

  • Creatine peptides can also improve strength and help build muscle.

While fitness enthusiasts have been using creatine protein powders for years, creatine peptides are becoming increasingly popular.

These particular peptides may be easier for the body to digest, which means they may cause fewer digestive problems than creatine protein.
