What is the Difference Between Collagen and Elastin?
🆚 Go to Comparative Table 🆚Collagen and elastin are two different types of proteins that play crucial roles in maintaining the structure, strength, and elasticity of the skin and other body tissues. Here are the main differences between them:
Collagen:
- Provides structure, strength, and support in the body.
- Found mainly in connective tissue, blood vessels, skin, and intestinal lining.
- Made up of 19 different types.
- Type 1 collagen fibers are 5-10 times stronger than steel.
- Production declines in the mid-20s.
- Causes of deficiency include aging, sun exposure, sugar, nicotine, and autoimmune disorders.
Elastin:
- Provides stretchiness and resilience in the body.
- Found in major blood vessels, lungs, elastic ligaments, tendons, and skin.
- Composed of a large, flexible molecule called tropoelastin.
- Elastin is approximately 1,000 times more flexible than collagen.
- Production declines or stops after puberty.
- Causes of deficiency include aging, sun exposure, nicotine, sudden weight loss/gain, stress, and medical issues.
Both collagen and elastin are made of fibroblasts and work together to maintain the overall health of the skin. However, they have distinct functions and characteristics that contribute to the skin's firmness, elasticity, and strength.
Comparative Table: Collagen vs Elastin
Collagen and elastin are two different proteins that contribute to the strength, elasticity, and support of the skin. Here is a table comparing their differences:
Collagen | Elastin |
---|---|
Most abundant protein in the bodies and skin, accounting for 90% of all dermal layers | Found in up to 10% of all dermal layers |
Found in connective tissue, blood vessels, skin, and intestinal lining | Found in major blood vessels, lungs, elastic ligaments, tendons, and skin |
Provides strength, support, and structure to skin | Provides resilience and elasticity to skin |
Declines in production in mid-20s by 1% each year | Production decline not well-documented |
Comprised of amino acids proline, glycine, and hydroxyproline | Comprised of proline, glycine, desmosine, and isodesmosine |
Has a triple helix structure with three polypeptide chains | Made up of numerous tropoelastin molecules linked together with desmosine and isodesmosine bridges |
Found in fascia, cartilage, tendons, ligaments, bone, and skin | Found in lungs, arteries, bladder, skin, elastic ligaments, and cartilage |
Provides tensile strength to the skin | Allows skin to stretch and return to its original shape |
Both collagen and elastin are synthesized by fibroblasts and play crucial roles in maintaining the structure and function of the skin. They work together to provide skin strength, firmness, and shape. However, they have distinct properties and functions, with collagen providing strength and elastin allowing the skin to stretch and return to its original shape.
