Proteins are the basis of many animal body structures (e.g. muscles, skin, and hair). They also form the enzymes which control chemical reactions throughout the body. Each molecule is composed of amino acids which are characterized by the inclusion of nitrogen and sometimes sulfur. The body requires amino acids to produce new proteins (protein ...
Animals generally have a higher requirement of energy in comparison to plants. [21] The macronutrients essential to animal life are carbohydrates, amino acids, and fatty acids. [6] [22] All macronutrients except water are required by the body for energy, however, this is not their sole physiological function.
There are three principal classes of macronutrients: carbohydrate, protein and fat. [1] Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per ...

Nutrient. A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists.

810 calories / 4 calories per gram = 203g of carbohydrates. Fat: 25% of 1800 = 450 calories. 450 calories / 9 calories per gram = 50g of fat. And now we have our final macros: 135g of protein ...
Protein is a nutrient needed by the human body for growth and maintenance. Aside from water, proteins are the most abundant kind of molecules in the body. Protein can be found in all cells of the body and is the major structural component of all cells in the body, especially muscle. This also includes body organs, hair and skin.
Animal-source foods are a diverse group of foods that are rich in bioavailable nutrients including calcium, iron, zinc, vitamins B12, vitamin D, choline, DHA, and EPA.
