| PROTEIN | LIPIDS | CARBOHYDRATES |
|---|---|---|
| DESCRIPTION Amino acid + amino acid = Protein All vital processes, including immunity and general metabolism, are carried out by proteins | Fatty acids + glycerol = lipids/fats Lipids act as energy storage and are similar to a larger source of energy | Glucose + glucose = Carbohydrates/starch Energy comes from carbohydrates. Carbohydrates are organic molecules that contain carbon, hydrogen and oxygen |
| SOURCE Protein is found in meat and fish eggs dairy products seeds and nuts, beans and lentils. | Lipids found in canola, corn, olive, peanut, soy, and sunflower oil | Carbohydrates found in wheat, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, cherry pie, sugar cane |
| USES Proteins build and repair tissues, muscles and bones, to make hormones and enzymes, support immune function, provide structural support, maintain fluid balance and as a secondary source of energy and to make hormones and enzymes. | Lipids are used to regulate hormones, insulation, components of cell membranes, cell signaling and absorption of fat-soluble vitamins, and provide energy during prolonged exercise. | Carbohydrates are used for storing energy, supporting digestive health, sparing protein for tissue repair, and playing roles in cell structure and communication. |
| FUNCTIONS Protein helps in the structure, function, and regulation of living organisms like digestion, and movement of muscles, and helps to build hair and nails. Protein also serves for cellular communication and acts as a messenger. | Lipids help with moving and storing energy, absorbing vitamins and making hormones. | The primary function of carbohydrates is to provide energy to the body. Carbohydrates help in digestion, absorbed into the stream as blood sugar (glucose) |
