Melanin Theory

.....you guys wont ever undrstand ANYTHING until you first understand the FUNDAMENTALS!!!!

melanogenesis starts in the CNS ...the mind, BRAIN w/ a hormone called

                       Alpha Melanocyte-Stimulating Hormone not the skin.


..if anyone can provide evidence that MSH is secreted from the skin...then as i said b4...i will forever leave and NEVER return...lol

No it doesn't.

Melanocytes are melanin-producing cells located in the bottom layer (the stratum basale) of the skin's epidermis, the middle layer of the eye  the inner earmeninges bones and heart. Melanin is a pigment which is primarily responsible for the color of skin.

Through a process called melanogenesis, these cells produce melanin, which is a pigment found in the skin, eyes, and hair. This melanogenesis leads to a long lasting tan which is in contrast to the tan that originates from oxidation of already existing melanin.

lol.... that was 95% of the neanderthals dna that was FUNGUS AND BACTERIA by the way

http://www.washingtonpost.com/wp-dyn/content/article/2010/05/06/AR2010050604423.html

The researchers removed half a gram of bone powder with a dental drill. More than 95 percent of the DNA in the sample belonged to bacteria and fungi, not to the Neanderthals. The scientists used a variety of techniques to eliminate the microbial DNA, recover the non-microbial DNA through polymerase chain reaction amplification, and assure themselves they had Neanderthal material and not modern human contaminants.

What the hell is your problem with fungus and bacteria?

if you cant understand the FUNDAMENTALS of where the production of melanin STARTS....then ur not going to be able understand this

The I suppose it would start with the release of melanocyte stimulating hormone releasing hormone(MSH-RH), which is created and released from the hypothalamus, which is part of the endocrine system.  So are you saying that melanin production is controlled by the endocrine system and not the central nervous system?

hypothalmus??...NEVER

no..your not listening..what ur providing isnt evidence as to WHERE MSH is released...as a matter of fact...lol this mentions nOTHING about MSH at all...
what this is..is the PATHWAY by which it takes...MSH stimulates the enzyme tyrosine

nice try but FAIL

lol dude...i like you...im going to leave you alone..cos is see that you obviously dont know what the hell your talking about

hint: HORMONES do the regulating...not enzymes
melelonogenesis STARTS w/ a HORMONE called Alpha Melanocyte-Stimulating Hormone
...in the PITUITARY gland...in the BRAIN (CNS) and a critical part HOW we deal w/ our environment

lets look at the etimology....ALPHA = first...MOST significant

and denotes its place as being FIRST on the scene

and ONCE AGAIN...i asked WHERE melanogenesis started...NOT anything about its releasing factor

Good job, Englsh. You've now started emulating your opponent for maximum lulz! This tactic should prove as utterly useless as common sense has. Over, and over again.

And melanogenesis starts IN THE SKIN. Before that, all there is are a bunch off hormones flying around your body.

You just contradicted YOURSELF. MSH is a RELEASING FACTOR for melanogenesis. If you are NOT talking about releasing factors, do not talk about MSH.

dude..ur lil diagram doesnt even mention MSH at all...so please take a seat because ur embarassin yourself

wow...you are really dumb

1)melanogenesis doesnt start w/ an ENZYME...it starts w/ a HORMONE called MSH...sooo i choose to ignore anyone who cant comprehend that...HORMONES send out messeges...Enzymes cant do this

its VERY important you understand that

and...there is no such thing as "junk" DNA (if that was what u were trying to say)...and nooo thats NOT what theyre saying

last i checked...fungus was between the plant and animal kingdom sooo why dont you FIRST learn how fungus grows (what type of energy) it needs..then you MIGHT understand the link between mtDNA eve, FUNGUS, MELANIN, LIGHT, HEAT, CARBON, ENERGY... jus to name a few

and HOW someone that once was able to produce melanin in mass abundance..could eventually LOSE that ability

BUT your NEVER going to understand if you cant understand the FUNDAMENTALS of melanogenesis

dont feel bad...science had it WRONG too

the problem w/ thinking melanogenesis STARTS in the skin...is that it doesnt

MELANOTANS main ingredient is MSH...which provides a temporary tan in its users

its NOT permanent cos MELANOGENESIS STARTS IN THE BRAIN

wrong again...melanogenesis starts in the BRAIN...if it didnt...everybody would look like this

..omg because..they took an injection (MSH) UNDER the skin where the melanocytes are..this stimulates the process that NaTURALLY occurs in "blacks"..because the process is suppose to start in the brain NOT the skin..this is why its TEMPORARY in whites who "tan"
