MACROMOLECULES

PROTEINS

CHEMICAL COMPOSITION

• Carbon, hydrogen, nitrogen, oxygen, and sometimes sulfur.

FUNCTION

• Considered a macronutrient, your body needs it in large amounts every day to function.
• When consumed, the body breaks it down into energy.
• Hair, and fingernails are also proteins, called characin.

CARBOHYDRATE

• any of various neutral compounds of carbon, hydrogen, and oxygen.
• Such as sugars, starches, and celluloses.
• Monosaccharide is one sugar unit. Examples: glucose, deoxyribose, ribose, fructose, and galactose.
• Disaccharide is two sugar units. Examples: sucrose, lactose, and maltose
• Polysaccharide is many sugar units. Examples: starch, glycogen, and cellulose.
