What are the six classes of nutrients and their functions?

Nutrients are classified into six which are namely: (1) carbohydrates, (2) proteins, (3) lipids, (4) vitamins, (5) minerals and (6) water. (1) Carbohydrates are essential nutrients that provide a ready source of energy for the body. Carbohydrate yield a kilocalorie which is the net unit of energy needed by our cells to perform their work.

What are the six major types of nutrients we need?

• Protein.
• Carbs.
• Fats.
• Vitamins.
• Minerals.
• Water.

Do you know the 6 classes of nutrients?

The food we eat contains nutrients, which are basically the substances the body needs for its basic functions. Since our bodies don’t synthesize nutrients, we must take them in form of diet. The body uses nutrients to produce energy, move, grow, breathe, detect and respond to the environment, excrete wastes, and reproduce.

Macronutrients

Macronutrients are the nutrients that the body needs in large quantities. They are the nutrients that give the body energy and help the body maintain its systems and structures. As part of a healthy diet, all four macronutrients should be consumed.

Micronutrients

Micronutrients are the essential nutrients that the body requires in lesser quantities to carry out bodily functions. They include all the essential vitamins and minerals. As opposed to macronutrients which are directly used to make energy, micronutrients aid in the process as being part of enzymes (i.e., they act as coenzymes).

What are the different types of nutrients?

1. carbohydrates. 2. lipids. 3. proteins. 4. water. 5. vitamins. 6. minerals. Nutrients can be further classified as either macronutrients or micronutrients and either organic or inorganic, as well as whether or not they provide energy to the body ( energy-yielding ).

What are organic nutrients?

The organic nutrients include the macronutrients (carbohydrate, protein, and fat) and vitamins. An organic nutrient contains both carbon and hydrogen. Organic nutrients can be made by living organisms and are complex, made up of many elements (carbon, hydrogen, oxygen, and sometimes nitrogen) bonded together.

What are the main components of proteins?

Proteins are large molecules composed of chains of amino acids, which are simple subunits made of carbon, oxygen, hydrogen, and nitrogen. Food sources of proteins include meats, dairy products, seafood, and a variety of plant-based foods, like beans, nuts, and seeds. The word protein comes from a Greek word meaning “of primary importance,” which is an apt description of these macronutrients as they are also known as the “workhorses” of life. Proteins provide structure to bones, muscles, and skin, and they play a role in conducting most of the chemical reactions occurring in the body. Scientists estimate that more than 100,000 different proteins exist within the human body. Proteins can also provide energy, though this is a relatively minor function, as carbohydrates and fat are preferred energy sources.

What are the functions of vitamins?

The fat-soluble vitamins are vitamins A, D, E, and K. Vitamins are required to perform many functions in the body , such as making red blood cells, synthesizing bone tissue, and playing a role in normal vision, nervous system function, and immune function. To give you an appreciation of the many functions of vitamins, the table below lists the 13 essential vitamins and their major functions. (Note: There is no need to memorize these vitamins and functions at this point in the course.)

What is the most important nutrient in the human body?

Water . There is one other nutrient that we must have in large quantities: water. Water does not contain carbon but is composed of two hydrogens and one oxygen per molecule of water. More than 60 percent of your total body weight is water .

What are the main sources of carbohydrates?

The major food sources of carbohydrates are grains, dairy products, fruits, legumes, and starchy vegetables, like potatoes. Non-starchy vegetables, like carrots, also contain carbohydrates, but in lesser quantities.

What is the best thing about food?

Food is one of life’s greatest pleasures. It offers amazing flavors, aromas, and textures. Food also provides our body with essential nutrients and non-nutrients like phytochemicals, both of which are vital to health. This section will discuss the six classes of nutrients and how these nutrients can be classified.

What are the minerals that help the body?

These small molecules serve a wide variety of purposes in your cells and tissues. Of the minerals, for example, calcium provides structure to your bones, potassium helps regulate blood pressure, iron transports oxygen through your blood and zinc helps keep your immune system healthy.

Is carbohydrate a structural molecule?

Similar to fat, digestible carbohydrate in your diet provides you with energy, although in a more readily available form than that in fat. This nutrient also acts as a structural molecule – for example, part of your liver and muscles contain a storage form of starch called glycogen. Indigestible carbohydrate, known as dietary fiber, doesn’t contribute fuel or structure to your cells, but it can help improve your digestive health by affecting how quickly food moves through your gut.

What are the different types of nutrients?

The macronutrients include carbohydrates (including fiber), fats, protein, and water. The micronutrients are minerals and vitamins. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy.

What are the elements that make up proteins?

Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen. The fundamental components of protein are nitrogen-containing amino acids, some of which are essential in the sense that humans cannot make them internally.

What are the macronutrients in the cell?

The macronutrients include carbohydrates (including fiber), fats, protein, and water. The micronutrients are minerals and vitamins. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy.

What are the molecules of carbohydrates and fat?

Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complexpolysaccharides (starch).

How much energy does a carbohydrate have?

Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram. , [17] though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance.

What are fats made of?

Hire writer. Fats are triglycerides, made of assorted fatty acid monomers bound to a glycerol backbone. Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen.

Do vitamins provide energy?

Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons. A third class of dietary material, fiber (i. e. , non-digestible material such as cellulose), is also required, [citation needed] for both mechanical and biochemical reasons, although the exact reasons remain unclear.
