Properties of matter
Anything that occupies space and has weight
Matter
Basic pure substances which cannot be broken down into simpler substances
Elements
Two or more atoms joined together by a chemical bond
Molecules
These help the body construct and renew itself
Proteins
This is what pH stands for
Potential hydrogen
Organic Chemistry
The three parts of an atom and their charges
Proton = Positive
Neutron = None
Electron = Negative
When the atoms that combine are different the result is a molecule that goes by this name
Compound
Carbohydrates
What acids and alkalis tend to taste like
Acids = Sour
Alkalis = Bitter
Study or all matter that is not alive has never been alive and does not contain carbon
Inorganic chemistry
Atom
Most common element in the universe
Hydrogen
These components fill the intercellular spaces in the skin
Lipids (intercellular cement)
The most accurate way to measure pH
pH Meter
A change in a substance that creates a new substance with chemical characteristics different from the original substance
The 5 elements that make up skin hair and nails
Carbon, Oxygen, Hydrogen, Nitrogen and Sulfur
In this process a substance loses an electron and oxygen is acquired
Oxidation
Thousands of amino acids connected lengthwise to form a chain
Polypeptide chain
If a solution has more positive hydrogen ions than negative hydroxide ions it is considered ________.
Acidic
Saponification
An example of unstable atoms or groups of atoms with odd(unpaired) number of electrons. These can cause oxidative damage which attacks collagen scaffolding in the skin.
Free radicals
When positive and negative ions join, they are held together by this bond
Ionic bond
Two saccharides linked together. An example would be table sugar
Disaccharide
If a solution has more hydroxide ions than hydrogen ions it is considered ________.
Alkaline
