What is the difference between carbohydrates fats and proteins

Cholesterol does not supply calories, but it is a building block of very important chemicals such as vitamin D. Remember, both lips and carbohydrates play an important role in delivering energy to cells.

When you eat carbs, they are quickly broken down into glucose, which fuels all muscle action. Carbohydrates can also be stored as glycogen in the muscles and liver for later use. Lipids are either stored in various fat cells throughout the body for later energy use or in the liver, per Oregon State University. Protein is composed of building blocks called amino acids.

Protein's primary function is to build and maintain body structures, such as muscle, bones and internal organs, and to synthesize important molecules such as antibodies, enzymes, neurotransmitters and various blood proteins, according to the NLM. Protein can be used for energy, but it's not the body's preferred source carbs are! One similarity between carbohydrates and lipids is that while the body can convert protein to glucose, neither carbs nor lipids can be converted to protein.

What's more, lipids, carbohydrates and protein are similar in the way that if you eat too much of them, they can be stored as fat. Even though all of the macronutrients can supply energy, a balanced diet providing all three will help the macros to perform their unique functions. The fats you consume are molecules called triglycerides, consisting of three fatty acids attached to a glycerol.

The chemical nature of the fatty acids contained within the lipid determines its physical characteristics. For instance, a fatty acid that is saturated with as many hydrogen atoms as it can hold is solid at room temperature, while unsaturated fatty acids are liquid. These macromolecules store energy within fat tissue, and they cushion your internal organs against trauma. They also form the structure of cell membranes and contribute to the synthesis of hormones.

Your cells contain two types of nucleic acids, ribonucleic acid and deoxyribonucleic acid, or RNA and DNA, respectively. They differ from the other macronutrients in that they are not a source of calories in your diet, and their role is strictly to direct the synthesis of new protein molecules.

Carbohydrates, also known as saccharides , are organic compounds made up of carbon, hydrogen, and oxygen. According to the number of building blocks monomers in a carbohydrate, they can be monosaccharides, disaccharides, oligosaccharides or polysaccharides. Carbohydrate monomers are the monosaccharides simple sugars. In fact, they are the simplest of all and contribute to the formation of other types. Monosaccharides include glucose and fructose. Furthermore, simple sugars serve as an energy source and a base product for synthesis.

Glucose exists as glycogen in our body. In plants, glucose exists as starch. Moreover, most starchy plant-based foods are high in carbs and provide 4 kilocalories per gram of carbohydrate. Oligosaccharides are helpful in maintaining gut bacteria, which helps in the synthesis of various products. Fats are organic compounds made up of carbon, hydrogen, and oxygen. The term fats includes all lipids and oils, as well as, cholesterol esters.

There are two types of fats; saturated and unsaturated.
