What are the chemical elements in human skin?

Answer 1

Skin and hair are both biological amides (carbon, oxygen, nitrogen based compound) which causes them to be remarkably inert (unlikely to react with chemicals), however, the pigmentation in skin is not so inert, hence why skin color can change from contact with chemical compounds.

Answer 2

Two calculations have been made for the chemical formula for the human body, one a 26-element formula calculation by American chemical engineer Libb Thims in 2002:

CE27HE27OE27NE26PE25SE24CaE25KE24ClE24NaE24MgE24FeE23FE23

ZnE22SiE22CuE21BE21IE20SnE20MnE20SeE20CrE20NiE20MoE19CoE19VE18

and another 22-element (empirical) formula calculation by American limnologists Robert Sterner and James Elser in 2000:

H375,000,000 O132,000,000 C85,700,000 N6,430,000 Ca1,500,000 P1,020,000 S206,000 Na183,000 K177,000 Cl127,000 Mg40,000 Si38,600 Fe2,680 Zn2,110 Cu76 I14 Mn13 F13 Cr7 Se4 Mo3 Co1

Answer 3

Many kinds of atoms, but as a living tissue skins is composed of mainly the 4 elements of life on Earth - Carbon, Hydrogen, Nitrogen and Oxygen.Sulfur (some amino acids) and Phosphorous (nucleic acids) are also present.Some metallic elements are also present as cofactors of some enzymes - Iron, Magnesium and others.

Answer 4

Oxygen, hydrogen, carbon, nitrogen, calcium, sodium, iron, zinc, sulfur, iodine, etc.

Answer 5

the chemical formula for hair is (Polymers)

Answer 6

40% Palmitic acid (saturated) CH3(CH2)14COOH

50% Oleic acid (unsaturated) CH3(CH2)7CH=CH(CH2)7COOH

and the rest is a long list of saturated and unsaturated

Answer 7

Carbon hydrogen and oxygen but mostly carbon

Answer 8

There is no formula for human tissue. Liver tissue, kidney tissue, muscle, everything else is different. Besides that human tissue is a mixture of substances. Mixtures have no exact formula.

Answer 9

hydrogen oxygen carbob and sulfur

Answer 10

Poo and pee is in most of ur skin
