Dietary Sources Of Carbohydrates Lipids And Proteins

Start studying 24 1 role of carbohydrates lipids and proteins carbohydrates.

Dietary sources of carbohydrates lipids and proteins. Depending on their chemical structure they come in two forms simple and complex. Fresh fruits and vegetables along with grains are all sources of carbohydrates. Protein from plant sources tends to be lower in saturated fat contains no cholesterol and provides fiber and other health promoting nutrients. Carbohydrates are the body s main source of energy.

Each gram of fat supplies the body with about 9 calories more than twice that supplied by proteins or carbohydrates. Carbohydrates are the body s main source of energy. Protein is also found in the dairy group. Because fats are such an efficient form of energy the body stores any excess energy as fat.

Lipids are the fats that we consume and they serve to store long term energy in the body. Healthy sources of carbohydrates include both food sources animal and plant products such as fresh fruits vegetables corn potatoes milk and milk products unhealthy sources include soda white bread artificial sugar pastries and other highly processed foods. This happens because all of the catabolic pathways for carbohydrates proteins and lipids eventually connect into glycolysis and the citric acid cycle pathways see figure 7 6 2. Choose healthful options within each food category daily.

There are both healthy and unhealthy sources of carbohydrates. Any excess protein you ingest is either burned as energy or converted to fat. Fats are the slowest source of energy but the most energy efficient form of food. Learn vocabulary terms and more with flashcards games and other study tools.

The fruit vegetables dairy and grain food groups all contain carbohydrates. All six groups provide raw materials for constructing new molecules but only carbohydrates lipids and proteins provide energy to sustain life processes. These macromolecules are broken down and absorbed into the body at different rates and into specific forms as they travel through the organs in the digestive system. Foods that contain carbohydrates lipids proteins and nucleic acids make up a balanced diet.

Lipids dietary sources triglycerides neutral fats. Carbohydrates fats and proteins are the major nutrients the body needs for growth repair movement and maintaining tissue and organ function.
