The study of all matter that is now living or was alive at one time, with carbon present.
organic chemistry
Amino acids that create proteins are linked together end to end by this.
peptide bonds
Atoms have three main parts: protons, neutrons and this.
electrons
These are basic substances that cannot be broken down into simpler substances.
elements
This can happen when putting a sodium hydroxide relaxer under a hair dryer.
Breakage the critical peptide bonds and destruction the protein structure. (Melts the hair)
Matter with definite weight and volume but no definite shape.
a liquid
Carbon, nitrogen, oxygen and hydrogen form the basis of this.
amino acids
What Atoms that are different form.
compound
The atomic number of a particular element indicates this.
The number of protons in a single atom.
These bonds found within hair help organize protein chains in order to build hair.
side bonds
Matter with definite weight but indefinite volume and shape.
gas
When amino acids combine to form the protein of the hair they take on this configuration.
spiraling
What atoms that are the same form.
element
The simplest atomic structure.
hydrogen
This bond is the backbone of all protein molecules.
peptide
Matter with definite weight, volume and shape.
solid
Hair consists of 97% of this.
keratin
Electrons have this type of electrical charge.
negative
Water freezing and becoming ice is an example of this type of change.
physical
These bonds found in the hair can be easily broken by heat or water.
hydrogen bonds
The scientific study of matter and the physical and chemical changes of matter.
chemistry
Protons have this type of electrical charge.
positive
This is the most abundant element in the earth's crust and the second most abundant element in the earth's atmosphere.
oxygen
The term used to identify anything that occupies space and has weight.
matter
Two or more of the same atoms joined together by a chemical bond.
molecule
