Hydrogen
Oxygen
Simple Carbohydrates --ANSWER--Easily broken down: 1-2 linked
sugars ( monosaccharides): fruits, vegetables, dairy, honey

, Lipids --ANSWER--Energy-rich organic compounds, such as fats,
oils, and waxes, that are made of carbon, hydrogen, and oxygen.
Lipids functions --ANSWER--Promoting brain function, providing
insulation and protective cushioning for organs. Support body's
immune system.

+ spherical)
Fiberous (elongated + insoluble)
Primary protein structure --ANSWER--Unique sequence of amino
acids are linked together to form a protein.
A carbon + hydrogen + carboxyl group + amino acid group = a
variable group or "R" group
secondary protein structure --ANSWER--coiling or folding of a
polypeptide due to H-bonding between amino acids
