Peptide

A short chain of two or more amino acids, linked by Peptide bonds. Peptides are smaller than proteins but can still perform a variety of biological functions, acting as hormones, neurotransmitters, and signaling molecules. The sequence of amino acids determines the peptide's specific function and structure. They play a vital role in various biological processes and are important in pharmaceuticals and cosmetics.

Peptide meaning with examples

• Scientists are studying the role of specific peptides in the regulation of appetite. Research suggests certain peptides can signal to the brain when to eat, while others trigger the feeling of fullness. This research may lead to development of new treatments for eating disorders.
• Cosmetic companies use peptides in anti-aging creams. The peptides work by stimulating collagen production, which can help reduce wrinkles and improve skin elasticity. These products often promise to give skin a more youthful appearance by building the skin structure.
• Many hormones, such as insulin, are peptides. Insulin, composed of two Peptide chains, regulates blood sugar levels. People with diabetes need insulin either produced by their own body or given to them to help them survive.
• During exercise, the body produces peptides that promote muscle growth and recovery. These peptides can assist in repairing muscle damage, and facilitating the uptake of amino acids needed for muscle protein synthesis.
