MACROMOLECULES

CARBOHYDRATE

• Includes starches, sugars, and cellulose
• A large group of organic compounds occurring in food and tissues
• Contain hydrogen and oxygen in a 2:1 ratio
• The monomer is a monosaccharide

COMPOSITION MAKEUP

• Hydrogen
• Carbon
• Oxygen
• (CHO)

FUNCTION

• Carbohydrates provide energy for the body
• Storage of energy and structural components
• Transport of energy and structural components

EXAMPLES:

• Pasta

2. BREAD

PROTEIN

• Also known as polypeptides
• Enzymes are a type of protein
• Proteins make up about 50% of an organism's biomass
• The monomer is amino acids

CHEMICAL COMPOSITION

• Carbon
• Hydrogen
• Oxygen
• Nitrogen
• (CHON)

FUNCTION

• Proteins help to repair the body
• Proteins are involved in the production of some hormones
• Enzymes, a type of protein, help speed up chemical reactions
• Proteins also help with the transportation of certain molecules

EXAMPLES

EXAMPLES

LIPIDS

• Most lipids are hydrophobic, water fearing
• Lipids have two main parts, glycerol heads and fatty acid tails
• A special type of lipid, phospholipids, make up the cell membrane
• Lipids are with saturated or unsaturated
• It's monomer is triglyceride

CHEMICAL COMPOSITION

• Carbon
• Hydrogen
• Oxygen
• (CHO)

FUNCTION

• Lipids store energy
• Make up the cell membrane
• Lipids protect vital organs in case of shock
• Lipids also prevent heat loss

EXAMPLES

EXAMPLES

NUCLEIC ACIDS

• It's monomer is nucleotide
• There are two types:
• RNA
• DNA

CHEMICAL COMPOSITION

• Carbon
• Hydrogen
• Oxygen
• Nitrogen
• Phosphorus (CHON P)

FUNCTION

• DNA stores genetic information
• RNA produces proteins and are messengers
