The building blocks that make up all proteins, including collagen, are called amino acids. An essential amino acid is one your body cannot make, so you have to get it from food or dietary supplements. Collagen is the most abundant protein in the body and is a key constituent of all connective tissues. Collagen provides the infrastructure of the musculoskeletal system, essential for mobility.
The Causes And Effects Of Collagen Loss By NewBeauty Staff | July 12, 2010 Collagen is a tough, almost rubbery protein that's created by cells called fibroblasts. Packed together as bundles, fibrous bands of collagen serve as the main support system of the dermis, the deepest layer of skin. Collagen gives skin its strength, and it makes skin firm and flexible with the help of elastin. Collagen is essential for young-looking skin because it gives structure to its cells. When collagen levels becomes depleted, the skin has little internal support, causing it to sag and contributing to wrinkles. Furthermore, when there is ample collagen in the skin, it's strong and more resistant to the effects of weight gain, so a lack of it can lead to a greater risk of stretch marks.
