Collagen's Structure:
Life is a string of complex molecules: polymers. And Nature's most abundant protein polymer is collagen. More than a third of the body's protein is collagen and makes up 70% of our skin.
Collagen is a triple helix formed by three extended protein chains that wrap around one another. many rodlike collagen molecules are cross-linked together in the extra cellular space to form unextendable collagen fibrils, that have the tensile strength of steel. The striping on the collagen fibril is caused by the regular repeating arrangement of the collagen molecules within the fibril. Elastin polypeptide chains are cross-linksd together to form rubberlike, elastic fibers. each elastin molecule uncoils into a more extended conformation when the fiber is stretched and will recoil spontaneously as soon as the stretching force is relaxed.

At this stage of our knowledge, we've found 13 kinds of vertebrate collagen, plus smaller molecules looking like collagen spare parts. Members of the family, we suspect. Each type has envolved to serve a distinct purpose. Collagen varies depending on the anatomical region. From muscle to bone to cartilage to blood vessel to nerves to various parts of the skin, which itself is the largest organ in the body.
Collagen has very interesting amino acid composition. It contains a lot of glycine and proline, as well as two amino acids that are not inserted directly by ribosomes ( hydroxyproline and hydroxylisine), the former as a rather large percentage of the total aminoacids. They are changed from proline and lysine in enzymatic processes.
The amino acid composition help to body decrease in muscle mass, we have less demand for energy and therefore our metabolism actually decreases. As a result, we burn less fat and sugars and what is not utilized is deposited throughout our bodies.
The end result, is a body that has less muscle and greater deposition adipose tissue, as well as a body that is even less efficient at eliminating the build up of toxins.
This then, is why we generally end up overweight. We recommend our capsules of 500 mg. (100/bottle) for best results in yor body.
