<h3>Overview</h3>
<p>Collagen is a <strong>triple-helical fibrous protein</strong> constituting the primary structural component of connective tissues. Produced via enzymatic extraction or acid hydrolysis from bovine, porcine, or marine sources, its molecular formula varies by type (e.g., Type I: C65H102N18O19). The standard CAS registry number for native collagen is 9007-34-5.</p>
<h3>Application</h3>
<ul>
<li><strong>Dermatology:</strong> Wound dressings and dermal fillers for tissue regeneration.</li>
<li><strong>Biomaterials:</strong> Scaffolds for tissue engineering and artificial organ fabrication.</li>
<li><strong>Nutrition:</strong> Hydrolysates in sports supplements for joint health support.</li>
</ul>
<h3>Precautions</h3>
<p>Strict storage below -20°C is required to prevent denaturation. Clinical use mandates screening for animal-derived pathogen risks; human allergy testing is recommended prior to implantation to mitigate hypersensitivity reactions.</p>
