Peptides and Proteins
Peptides are short chains of amino acids linked by peptide bonds, whereas proteins are longer and more complex amino acid chains that can adopt functional three-dimensional structures. Both types of compounds are essential for various biological functions, such as catalysing reactions (enzymes), immune defence (antibodies), and cellular signalling. Proteins have a hierarchical structure, including the amino acid sequence, secondary, tertiary, and quaternary structures. Peptides are used in pharmaceutical and cosmetic therapies due to their specific biological properties, such as in the treatment of metabolic diseases or enhancing cellular regeneration. Proteins, on the other hand, have applications in biotechnology, nutrition, and regenerative medicine.
At CymitQuimica, we offer high-purity peptides and proteins for research in biotechnology and therapeutic applications.
