_________ Bonds Hydrogen Bonds: When an atom of hydrogen is attracted to two atoms instead of only one. Hydrogen bonds attract molecules to each other, but do not technically bond atoms together . Bonding electrons are shared unequally by the hydrogen and oxygen atoms: negative charge (-) forms at ______ end positive charge (+) forms at _______end When the electrons in a covalent bond are not equally shared, the molecule is _____.

Carbon Little Atom, Big Deal The chemical basis of life. Abundant in all known life forms. Essential to complex organic macromolecules, because each carbon atom can form ____ bonds (usually involving hydrogen , oxygen and/or nitrogen). Able to form polymers (big organic molecules). The atoms can bond with each other to form long chains. Sometimes the ends of these chains join together to form a ring. Double bonds form when atoms share two electrons (two covalent bonds).

Organic Molecules - Carbohydrates • “________ hydrates” • One carbon molecule to one water molecule (_______) n. • _________ is a synonym for carbohydrate . • The prefixes on the word “saccharide” relates to the size of the molecule (mono-, di-, tri- poly-). You probably know that chocolate cake is full of refined sugars…carbs. You may not know that boogers contain carbs as well. Boogers are dried-up mucus and dirty nose debris. Mucus is made mostly out of sugars and protein . Looks like this little punkin is double dipping. Bon appetite!
