Study Notes

Food molecules, specifically carbohydrates and proteins, play crucial roles in providing the body with essential nutrients. Carbohydrates are primarily responsible for supplying immediate energy, while proteins contribute to maintaining tissues and facilitating various bodily functions.

Carbohydrates

Carbohydrates are classified into three types based on their molecular structure: monosaccharides, disaccharides, and polysaccharides. Monosaccharides, also known as simple sugars, are single sugars like glucose, fructose, and galactose. They are the smallest carbohydrate molecules and are typically used by the body for immediate energy. Simple carbohydrates are found in foods like fruits, dairy products, honey, and maple syrup. Complex carbohydrates, on the other hand, are formed by linking multiple monosaccharides together. They provide a slower energy supply compared to simple carbohydrates, making them ideal for sustained energy throughout the day.

Proteins

Proteins are composed of amino acids, which are organized into long chains. Proteins provide structural support and are involved in various biochemical processes in the body. Some amino acids are considered essential, meaning they cannot be produced by the human body and must be obtained through the diet. Essential amino acids include isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Although protein is not typically used directly for energy, it can be broken down and used for energy generation if insufficient calorie intake occurs.
