The avian eggshell membrane, the thin, fibrous film lining the inside of an egg, is surprisingly composed of up to 90% protein. This fact answers the question, 'Is the eggshell membrane a protein?' with a resounding yes, but the story of its composition and benefits goes much deeper than that.

Dicalcium phosphate dihydrate (DCPD) is a calcium phosphate compound found in dietary supplements, toothpastes, and food products, used to provide essential minerals like calcium and phosphorus for bone and dental health. Its use across various industries is driven by its nutritional and functional properties.

Comprising up to 80% of its weight, silk fibers are predominantly a natural protein called fibroin. This protein, along with another called sericin, is secreted by silkworms and is the fundamental building block of the luxurious fabric, confirming that yes, silk does contain protein.

According to the Food and Drug Administration (FDA), food-grade tricalcium phosphate (TCP) is generally recognized as safe (GRAS) for use in numerous food products. This versatile compound is valued not only as a calcium and phosphorus supplement but also for its industrial applications and significant potential in advanced biomedical fields.

While it's a common misconception, a chicken eggshell is actually composed of more than 95% calcium carbonate, not hydroxyapatite. However, recent advances in materials science show that these waste shells can be sustainably synthesized into hydroxyapatite, a key component of human bone and enamel.

As the main mineral component of bones and teeth, calcium phosphate plays a critical role in human physiology. This versatile compound, commonly known as calcium phos, extends far beyond the human body, with a wide array of applications in food processing, agriculture, and biomaterials.
