Saliva is a mixture of

Saliva is a mixture of various chemicals so there is no chemical formula for saliva by itself.

The specific contents according to wikipedia are:
Produced in salivary glands, human saliva is 98% water, but it contains many important substances, including electrolytes, mucus, antibacterial compounds and various enzymes.[1]

It is a fluid containing:

* Water
* Electrolytes:
o 2-21 mmol/L sodium (lower than blood plasma)
o 10-36 mmol/L potassium (higher than plasma)
o 1.2-2.8 mmol/L calcium (similar to plasma)
o 0.08-0.5 mmol/L magnesium
o 5-40 mmol/L chloride (lower than plasma)
o 25 mmol/L bicarbonate (higher than plasma)
o 1.4-39 mmol/L phosphate
o Iodine (mmol/L usually higher than plasma, but dependent variable according to dietary iodine intake)
* Mucus. Mucus in saliva mainly consists of mucopolysaccharides and glycoproteins;
* Antibacterial compounds (thiocyanate, hydrogen peroxide, and secretory immunoglobulin A)
* Epidermal growth factor or EGF
* Various enzymes. There are three major enzymes found in saliva.
o α-amylase (EC3.2.1.1). Amylase starts the digestion of starch and lipase fat before the food is even swallowed. It has a pH optima of 7.4.
o lingual lipase. Lingual lipase has a pH optimum ~4.0 so it is not activated until entering the acidic environment of the stomach.
o Antimicrobial enzymes that kill bacteria.
+ Lysozyme
+ Salivary lactoperoxidase
+ Lactoferrin[10]
+ Immunoglobulin A[10]
o Proline-rich proteins (function in enamel formation, Ca2+-binding, microbe killing and lubrication)[10]
o Minor enzymes include salivary acid phosphatases A+B, N-acetylmuramoyl-L-alanine amidase, NAD(P)H dehydrogenase (quinone), superoxide dismutase, glutathione transferase, class 3 aldehyde dehydrogenase, glucose-6-phosphate isomerase, and tissue kallikrein (function unknown).[10]
* Cells: Possibly as much as 8 million human and 500 million bacterial cells per mL. The presence of bacterial products (small organic acids, amines, and thiols) causes saliva to sometimes exhibit foul odor.
* Opiorphin, a newly researched pain-killing substance found in human saliva.

Silva isn't a compound that's

Silva isn't a compound that's why it hasn't any formula. Its just a saturated mixture. :D

Only chemical compounds have formulas. Saliva is not a compound. It is a mixture.


Thanks for the help.

Mostly, H2O :)

lol that what u think

Saliva :?:
A seturated mixture , perhaps :?: LOL ...

Saliva is produced in and secreted from the salivary glands. It is a fluid containing water, electrolytes, mucus, and various enzymes. In human saliva, amylase starts the digestion of starch before the food is even swallowed.
