Hydroxyproline is found in few proteins other than collagen. For this reason, hydroxyproline content has been used as an indicator to determine collagen and/or gelatin amount. However, the mammalian proteins elastin and argonaute 2 have collagen-like domains in which hydroxyproline is formed.
Procollagen-proline dioxygenase, commonly known as prolyl hydroxylase, is a member of the class of enzymes known as alpha-ketoglutarate-dependent hydroxylases.These enzymes catalyze the incorporation of oxygen into organic substrates through a mechanism that requires alpha-Ketoglutaric acid, Fe 2+, and ascorbate.
This (Gly-X-Y)n sequence is repeated 343 times in the type III collagen molecule. Proline or hydroxyproline is often found in the X- and Y-position giving the triple helix stability. In addition to being an integral structural component of many organs, type III collagen is also an important regulator of the diameter of type I and II collagen ...
The mutation in the gene encodes prolyl 3-hydroxylase 1. The malfunctioning prolyl 3-hydroxylase in leprecan leads to inappropriate collagen folding. This is due to the instability caused by the absence of hydroxyproline. Hydroxyproline is the product of hydroxylating a proline residue. [5]
The main side effects heroin causes on appearance according to New Health Advisor are: Weight loss due to loss of appetite, or because a heroin abuser may not prioritize eating.

In 1954, Ramachandran & Kartha (13, 14) advanced a structure for the collagen triple helix on the basis of fiber diffraction data. It consists of a triple helix made of the repetitious amino acid sequence glycine-X-Y, where X and Y are frequently proline or hydroxyproline. [2] [3] Collagen folded into a triple helix is known as tropocollagen.
