For example, in the UK the third edition of The Composition of Foods [3] presented data on vitamin content of foods. However, due to the amount of information already available and in order to avoid the need to analyse every food for every vitamin, values from the scientific literature were included, although the tables are still predominately ...
The tables below include tabular lists for selected basic foods, compiled from United States Dept. of Agriculture sources.Included for each food is its weight in grams, its calories, and (also in grams,) the amount of protein, carbohydrates, dietary fiber, fat, and saturated fat. [1]
Conditionally essential nutrients are certain organic molecules that can normally be synthesized by an organism, but under certain conditions in insufficient quantities. In humans, such conditions include premature birth , limited nutrient intake, rapid growth, and certain disease states. [ 14 ]
This list is a categorization of the most common food components based on their macronutrients. Macronutrients can refer to the chemical substances that humans consume in the largest quantities (See Nutrient);
Essential nutrients cannot be synthesized by the body, and must be obtained from food. Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complex polysaccharides (starch, glycogen).
The sources of energy can be light or chemical compounds; the sources of carbon can be of organic or inorganic origin. [ 1 ] The terms aerobic respiration , anaerobic respiration and fermentation ( substrate-level phosphorylation ) do not refer to primary nutritional groups, but simply reflect the different use of possible electron acceptors in ...

This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide , water and oxygen were necessary for the growth of life.
