Two amino acid storage proteins in animals are casein and ovalbumin. Seeds, particularly of leguminous plants, contain high concentrations of storage proteins. Up to 25 percent of the dry weight of the seed can be composed of storage proteins. The best known storage protein in wheat is the prolamin gliadin, a component of gluten.
Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...
[39] [50] [51] When food protein intake is periodically high or low, the body tries to keep protein levels at an equilibrium by using the "labile protein reserve" to compensate for daily variations in protein intake. However, unlike body fat as a reserve for future caloric needs, there is no protein storage for future needs. [2]
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]
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location ...
Natural protein concentrates (often used in bodybuilding or as sports dietary supplements): Soy protein isolate (prepared with sodium or potassium): 80.66; Whey protein isolate: 79; Egg white, dried: 81.1; Spirulina alga, dried: 57.45 (more often quoted as 55 to 77) Baker's yeast: 38.33; Hemp husks 30

Prolamins are a group of plant storage proteins having a high proline amino acid content. They are found in plants, mainly in the seeds of cereal grains such as wheat ( gliadin ), barley ( hordein ), rye ( secalin ), corn ( zein ), sorghum ( kafirin ), and oats ( avenin ).
