Learn: Carbohydrates and Lipids in Diet and Health

Welcome!Welcome back! You've already learned about the heart and blood vessels, the cardiac cycle, and blood clotting. Today, we'll build on that knowledge by exploring how carbohydrateslipids impact diet and health.

What are Carbohydrates?Carbohydrates are molecules made up of carbon, hydrogen, and oxygen. They provide energy to the body through respiration. There are two main types: simple carbohydrates, like glucose, and complex carbohydrates, like starch.

What are Lipids?Lipids are fats and oils made up of glycerol and fatty acids. They are essential for storing energy, insulating the body, and protecting organs. Lipids also play a role in building cell membranes and producing hormones.

How are Carbohydrates and Lipids Digested?Carbohydrates are broken down into glucose by enzymes like amylase and maltase. Lipids are digested into glycerol and fatty acids by lipase, with bile aiding in their emulsification. This process occurs in the digestive system.

Carbohydrates and Lipids in HealthAn imbalance in carbohydrates and lipids can lead to health issues. Excess carbohydrates can result in obesity and diabetes, while too many saturated lipids can cause cardiovascular disease.
