Peptides are short chains of amino acids, while proteins are generally longer and more complex chains that fold into specific structures. Some peptides act as signaling molecules, helping regulate processes such as hormones, inflammation, and cell communication. In Vitro research is also commonly used to study how specific peptides interact with cells or biological pathways under controlled laboratory conditions. Their safety and effectiveness depend heavily on the specific peptide. Some peptide based medicines have strong clinical evidence, while many supplements and research compounds have limited human data.
