Like Y-DNA STRs, autosomal STRs are counts of repeated genetic code. As autosomal DNA recombines each generation, the number of markers shared with a specific ancestor is reduced by half each generation.
Heroin acts as a lipid soluble âprodrugâ within the brain, meaning that heroin itself is inactive but it is metabolized into an active form within the body. After crossing the blood-brain barrier, heroin is metabolized into morphine, which actively binds to opiate receptors in the brain producing the high.
Morphine is the principle alkaloid in opium (derived from poppy  plants). It is the active substance released by the metabolism of  heroin (morphine diacetate) in the human â¦ body.    Morphine is an opiate-narcotic pain reliever used to treat  moderate to severe pain.  Because you are adding weight (sulfate) to morphine (base), the  weight of Morphine Sulfate will have less morphine (base) in it.    For example: 20mg of morphine sulfate has ~15mg of morphine (the  other 5mg are due to sulfate molecule and 5 water molecules).
