About Author

Collagen is the major insoluble fibrous protein in the extracellular matrix and in connective tissue. In fact, it is the single most abundant protein in the animal kingdom. There are at least 16 types of collagen, but 80 – 90 percent of the collagen in the body consists of types I, II, and III (Table ). Jan 18,  · The collagen molecule, also known as the “tropocollagen”, is part of larger collagen aggregates such as fibrils. The whole molecule is approximately nm long and nm in diameter/5(5).
