DESCRIPTION/OBJECTIVE

This course is a study and investigation into chemistry and chemicals of everyday life. The
study of chemistry is studied along with practical applications. Topics of study include basics
of: organic chemistry, food chemistry, chemistry in everyday life, chemistry and medicine.

Organic chemistry is taken as a prerequisite knowledge for polymerization and polymer

Food chemistry is limited to essential topics suited to the grade level, such as preservatives,
food preservation, food processing and chemistry of changes occurring during processing,
storage and utilization.

Chemistry in Everyday Life are selected based on practically to students, as well as

Chemistry and Medicine is chosen for health and wellness in order to promote quality life.

COVERAGE OF THE STUDY:

Organic Chemistry First Quarter

Food Chemistry Second Quarter

Chemistry in Everyday Life Third quarter

Chemistry and Medicine Fourth Quarter

There are millions of organic compounds. The number of organic or carbon compounds far
exceeds the number of compounds of all the other elements combined.
Proteins, carbohydrates, vitamins, enzymes, and hormones are some of organic compounds
that affect the human body. Organic compounds such as paint, varnish, plastic, medicine,
glue detergent, dye, rubber, and fibers for clothes are common.
