ADHESION
SMALLEST COMPLETE UNIT OF ELEMENT
ATOM
chemical substances that cannot be
decomposed or broken down into simpler units by any
chemical reaction
ELEMENT
no. of protons written as superscript
before the chemical symbol
ATOMIC NUMBER
no. of protons and neutrons in a given atom
written as superscript after the chemical symbol
ATOMIC MASS
composed of atoms of 2 or more elements
chemically united in fixed proportions
COMPOUND
the smallest complete unit of compound
MOLECULES
the attractive interaction of electrons
of 2 atoms or group of atoms
CHEMICAL BONDING
Form when an ionic compound is mixed with
water to form a solution.

GLYCOGEN
are fatty, waxy, or oily substances in nature
LIPIDS
lipids with one, two, or three fatty acids that are attached to an alcohol
named glycerol
FATS
consist of two fatty acid tails attached to a phosphate head.
PHOSPHOLIPIDS
complex lipid structures consisting of fatty acids bound to alcohol or
carbon chains.
WAXES
are lipids with carbon rings instead of fatty acid chains
STEROIDS
compounds composed of one or more chains of amino acids
PROTEINS
Long protein chains are sometimes referred…
POLYPEPTIDE CHAINS
small organic molecules that can act as energy carriers, coenzymes,
chemical messengers, and as the subunits of DNA and RNA
