Macronutrients
The nutrients we need in large quantities to provide our body with energy
Examples of macronutrients
Carbohydrates, lipids, proteins, water
Micronutrients
the vitamins and minerals we need in smaller quantities
Examples of Micronutrients
Iron, Vitamin A, Salt, Vitamin D, Iodine, Folate, Zinc
what do Organic Compounds contain?
Carbon, Hydrogen, and usually oxygen
What are the important classes of organic compounds?
Carbohydrates, lipids, proteins, nucleic acids.
What do carbohydrates do?
Provides cells with quick and short-term energy, and is also the source of dietary fiber
What do lipids do?
Provides cells with long-term energy, and make up biological membranes
What do proteins do?
Provides cell structure, sends chemical signal, and speeds up chemical reactions
What does water do?
A medium for biochemical reactions, transport, and thermoregulation
What do vitamins do?
Helps energy release from macronutrient metabolism, bone health, and immune function
What do minerals do?
Contributes to mineralization, blood oxygen, transport, muscle function, and balance cellular fluids.
What is the MOST important energy source for metabolism?
Carbohydrates :D
What are the 4 major types of carbohydrates?

What is glucose?
a molecular sugar that is made up of carbon, hydrogen, and oxygen.
What is the ratio for Glucose?
1:2:1
What is the formula for glucose?
C6H12O6
What is the product of glucose molecules combining?
Disaccharides and polysaccharides (through a form of synthesis)
What is Dehydration Synthesis?
Linkage of a monosaccharide to another monosaccharide, disaccharide, or polysaccharide by the removal of a water molecule.
What are lipids?
Water-insoluble macromolecules
