Chemistry Notes

Bonds Energy is stored in bonds Energy is required to form bonds

Organic Compounds Compounds that contain Carbon Carbon can bond with up to four other atoms so it can be the backbone form large molecules

Organic Compounds Carbohydrates –Provides quick energy –CHO in 1:2:1 ratio –EX glucose sucrose starch cellulose glycogen

Organic Compounds Lipids –Stored energy, insulation –CHO –EX fats oils waxes phospholipids steroids cholesterol

Organic Compounds Proteins –Structure, transport, movement –CHON –EX collagen hemoglobin muscles enzymes

Organic Compounds-Proteins Enzymes –Biological catalysts –Specific enzymes help break down specific substrates –EX sucrase breaks down sucrose

Organic Compounds Nucleic Acids –Stores genetic information –CHONP –EX DNA RNA

pH pH=power of hydrogen 7=neutral ACIDS: –pH of less than 7 –more H+ BASES: –pH of more than 7 –more OH-
