Casomorphin is a peptide sequence that is found in whey protein called casein, and which can be addictive to humans and cause an opiate effect. Peptides (from the Greek πεπτος, digestable), are the family of molecules formed from the linking, in a defined order, of various amino acids. ... Whey or milk plasma is the liquid remaining after milk has been curdled and strained; it is a byproduct of cheese or casein making with several commercial uses. ... A representation of the 3D structure of myoglobin, showing coloured alpha helices. ... See Casein paint for information about casein usage in artistic painting. ... The term opiate refers to the alkaloids found in opium, an extract from the unripe seeds of the opium poppy (). It has also traditionally referred to natural and semi-synthetic derivatives of morphine. ...

All proteins are chains of amino acids. In the human digestive system, these proteins are chopped up into small segments of amino acid sequences. When casein is broken down by this mechanism, casomorphin is one of the small sequences produced. This sequence travels to the brain, where it may bind to opiate receptors and cause an effect similiar to that produced by endorphins and the other similiar peptides. In chemistry, an amino acid is any molecule that contains both amino and carboxylic acid functional groups. ... Endorphins are endogenous opioid biochemical compounds. ...

There are several different casomorphins, which are all opioid peptides. They are formed during digestion of the casein protein from bovine milk. They are usually broken down into amino acids by digestion enzymes, but in some individuals they are not. They are then accumulated in the body over time and can lead to a peptide poisoning. This is particularly often reported in patients with ADHD, autism and schizophrenia. Withdrawal symptoms are quite common, more so than in the case of gluten peptides (gluten exorphines and gliadorphin).
