MACROMOLECULES

CARBOHYDRaTES

• Any large group of organic compounds occurring in foods and living tissues.
• Carbs are made up of monomers called monosaccharides. Includes starch and sugar.
• Carbohydrates are used by the body for energy and structural support.
• Some examples of this molecule include monosaccharides, disaccharides, and polysaccharides.
• Carbs are mainly composed of hydrogen, carbon, and oxygen.

PROTEINS

• Proteins are molecules consisting of one or more chains of amino acids.
• Proteins are used to build cells and do much of the work inside organisms.
• These molecules mainly are made of carbon, hydrogen, oxygen, and nitrogen.
• The most common protiens are meat, fish, poultry, eggs, cheese, nuts.

LIPIDS

• A lipid is a fatty acid that is nonpolar. Triglyceride is the subunit.
• Fats are made of glycerol and 3 fatty acid chains.
• Lipids serve as waxy coverings on plants, pigments, and steroids.
• Lipids are made of carbon, hydrogen, and oxygen.
• Some examples are waxes, oils, and fats.

NUCLEIC ACIDS

• Nucleic acids molecules consist of many nucleotides.
• They carry the genetic information in a cell.
• DNA and RNA help the cell make proteins.
• The elements are carbon, sugar, phosphate and nitrogen base.
• The examples are DNA and RNA
