Peptides in 30 seconds
Peptides are short chains of amino acids, the building blocks of proteins. Your body makes many of its own. People look into them for goals like weight loss, muscle, skin, sleep and aging.
What they are
Chains of about 2 to 50 amino acids. One is oxytocin, which your body makes. It has 9 amino acids.
What people look into
The goals with the most pages are aging (67), muscle and exercise (41) and weight (35).
How we sum up studies
When we sum up a study, we say whether it was done in people, animals or cells.
By goal

How peptides work, in three steps
A short chain
Amino acids link up into a short chain.
A shape that fits
The chain's shape lets it fit certain spots on cells, a bit like a key in a lock.
A signal
That fit can turn a signal in the body up or down. Which signal depends on the peptide.
