Macromolecules
Macromolecules are large molecules that are found in living things. They are made up of smaller units called monomers. The 4 major types of
macromolecules include carbohydrates, lipids, proteins, and nucleic acids.

Macromolecules are large molecules that are found in living things. They are made up of smaller units called monomers. The 4 major types of
macromolecules include carbohydrates, lipids, proteins, and nucleic acids.
Lipids include fats, oils, and waxes that are made up of
carbon, hydrogen, and oxygen atoms. They provide stored
energy, waterproof coverings, and make up
cell membranes. The monomers of
lipids are fatty acids. Examples include
butter, vegetable oil, and animal fat.
Carbohydrates are the main source of energy of
living things. They include sugars and starches
that are made up of carbon, hydrogen, and
oxygen atoms. The monomers of carbohydrates
are monosaccharides. Examples include bread,
pasta, fruit, and candy.
Proteins are essential for the structure and function of
cells and tissues in living things. The monomers of proteins
are amino acids which are composed of carbon,
hydrogen, oxygen, and nitrogen atoms. Living things
obtain proteins from consuming meats, nuts, and legumes.
Nucleic acids are essential for storing and transmitting
cellular information. DNA and RNA are both examples of
nucleic acids. They are made up of carbon, hydrogen,
oxygen, nitrogen, and phosphorus atoms. The
monomers of nucleic acids are nucleotides.
