Dr. Ria Smit praat oor peptiedes, wat deesdae ‘n gonswoord in die skoonheidsbedryf is.
Sy verduidelik wat dit is, en hoe dit gebruik word.
Aminosure is die kleinste boublokke van proteïene. Peptiede is aminosure wat in spesifieke volgordes in kort kettings verbind is. Voorbeelde van peptiede is insulien, GLP-1 ens.
Maar kan dit jou jonger en mooier maak?

Peptides are short chains of amino acids, the “building blocks” of proteins. While proteins contain 50 or more amino acids, peptides are shorter (usually 2 to 50 amino acids long). They act as biological messengers that instruct cells to perform specific tasks, like repairing tissue, regulating hormones, or fighting bacteria. [1, 2, 3, 4]
Peptides serve diverse roles across wellness, medicine, and cosmetics: [1, 2, 3]
Synthetic and naturally occurring peptides are utilized in medical treatments and wellness therapies to target specific body functions. They are known for promoting muscle growth, accelerating injury recovery, modulating the immune system, and aiding in weight loss (e.g., GLP-1 peptides). [1, 2, 3]

Dietary Sources
You can get dietary peptides by consuming foods that contain high-quality amino acids. [1]
Plant sources: Soy, oats, wheat, flaxseed, hemp seed, and legumes like beans, lentils, and peas. [1, 2]
Animal sources: Meat, fish, shellfish, eggs, and dairy.
Types of Peptides
Scientists categorize peptides by their length and biological activity: [1, 2, 3, 4]
- Oligopeptides: Short chains (fewer than 10-20 amino acids).
- Polypeptides: Longer chains (more than 20 amino acids).
- Bioactive Peptides: Specific peptides that provide health benefits beyond basic nutritional value (e.g., milk-borne peptides that have antioxidative or antimicrobial properties). [1, 2, 3]
