I just learned that human hair from China (Cysteine) is a common food additive. I am grossed out! Is

Production



Currently the cheapest source of material from which food grade L-cysteine may be purified in high yield is by hydrolysis of molecules in human hair. Other sources include feathers and pig bristles. The companies producing cysteine by hydrolysis are located mainly in China. There is some debate whether or not consuming L-cysteine derived from human hair constitutes cannibalism. Although many other amino acids were accessible via fermentation for some years, L-Cysteine was unavailable until 2001 when a German company ("Wacker Chemie"?) introduced a production route via fermentation (non-human, non-animal origin.

I hope not that is nasty.

Well, they eat dogs don't they?

I don't know about that.. But this is one of the many reasons i only eat foods I make from scratch.

It's an amino acid.. not hair.. found in hair and nails



cysteine



(s娌玸楹搕鑶縩) , organic compound, one of the 20 amino acids commonly found in animal proteins. Only the L-stereoisomer participates in the biosynthesis of mammalian protein. It is particularly abundant in the proteins of hair, hooves, and the keratin of the skin. Cysteine's importance is related to the presence of a sulfur-containing thiol group in its side chain. This group participates in the catalytic reactions of certain enzymes, such as that of papain, the enzyme from papaya latex used to make commercial meat tenderizers. The thiol group of one cysteine residue is capable of combining with the thiol group of another to form a disulfide bridge, either linking two peptide chains together, as in the case of insulin, or causing a single peptide chain to fold back on itself, making a loop. This latter effect on the secondary structure of proteins is evidently of great importance in maintaining the proper configuration of both structural proteins and enzymes. Two cysteine molecules linked together by a disulfide linkage make up the amino acid cystine, often occurring as a separate entry in lists of common amino acids. A major complication of cystinuria, an inherited metabolic disease, one of whose symptoms is a twentyfold to thirtyfold increase in urinary excretion of cystine, is the precipitation of this relatively insoluble amino acid in the kidney, impairing its function. A similar sort of renal failure often accompanies cystinosis, another inherited disease. Cystine was isolated from a urinary calculus in 1810 and from horn tissue in 1899. The reduction of cystine to cysteine was reported in 1884, and the structures of the two amino acids were proved by chemical synthesis in 1903閳?. Neither cysteine nor cystine is essential to the diet of man; cystine and cysteine are interconvertible, and cysteine is made in the body from serine and methionine.

Yes, and no. Cysteine is an amino acid that is a part of the DNA code. It is not classified as an essential amino acid because the human body is capable of producing it on its own. Cysteine additives are sometimes introduced to food products, and one way that food-grade cysteine is produced is to hydrolyze the molecules in human hair, feathers, and pig bristles. Hydrolysis is a chemical process that breaks apart the individual molecules in a substance -- such that it no longer resembles the substance. There have been developed newer methods of production that don't involve human hair.

What food/ drink makes human hair grow faster?

eggs. read up on them from medline and google and or yahoo "egg benefits"



What food/ drink makes human hair grow faster?

I dont drink milk and I am as healthy as grown woman could be. Taking vitamins will help and promote natural growth, there are many sorts of vitamins for promotion of different things. So contact your local health store and get more info.



What food/ drink makes human hair grow faster?

Taking vitamins allows for human growth.



What food/ drink makes human hair grow faster?

How about a wig? or extensions



What food/ drink makes human hair grow faster?

Take Biotin it promotes hair growth but watch out it also makes your nails grow.....lol



What food/ drink makes human hair grow faster?

All the suggestions you've gotten will make your hair grow in healthier, shinier, and less prone to breakage, but nothing really makes it come in faster. The follicle produces keratin (hair) at its own set rate. You'll just have to rock a shaved head for a while.

Is is normal for human hair to dissolve in a fairly mild bleach solution when cleaning a comb?

why are you soaking you combs in bleach to start ..... and yes it possibly can since its breaks down the DNA structure of the hair and cells

apparently

How do you keep human hair weaves moisturized, and tangle-free?

Try not to comb it whilst wet. Avoid using too many oils, sheens, holding sprays etc. Try light polishers it gives the hair sheen and also keeps it soft. Try not to regularly use heated appliances such as straightners and tongs this dries out the hair a lot. Try wrapping your hair to maintain a style. It's also fact that none of the human hair that can be bought is tangle-free they all loose their movement after a while I'm afraid. Buying good quality human hair may also help. Let me know if you need anymore advice.



Goodluck

How long can a human hair grow if not cut?

Depends on how healthy the hair is. Most thinner hair will break off when it grow too long from the root.



Check out the Guiness Book of World Records online to find out who has the longest hair in the world today.

57.69 inches (j.k.) i dont really know!! LOL!!!!



How long can a human hair grow if not cut?

as long as your alive

Is the pigment observed in the human hair is produced by the same cells that produce the pigment in

in our skin u mean?



no. melanin is in our skin.



but it doesnt affect your hair color
