Excessive protein intake may increase calcium excretion in urine, occurring to compensate for the pH imbalance from oxidation of sulfur amino acids. This may lead to a higher risk of kidney stone formation from calcium in the renal circulatory system. [2] One meta-analysis reported no adverse effects of higher protein intakes on bone density.

Protein toxicity is the effect of the buildup of protein metabolic waste compounds, like urea, uric acid, ammonia, and creatinine. Protein toxicity has many causes, including urea cycle disorders, genetic mutations, excessive protein intake, and insufficient kidney function, such as chronic kidney disease and acute kidney injury .
The words protein, polypeptide, and peptide are a little ambiguous and can overlap in meaning. Protein is generally used to refer to the complete biological molecule in a stable conformation, whereas peptide is generally reserved for a short amino acid oligomers often lacking a stable 3D structure. But the boundary between the two is not well ...
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

The recommended daily allowance (RDA) for protein is 0.8 grams per kilogram (0.36 grams per pound) of body weight, which doesn’t account for activity level or dynamic metabolic needs (like ...
Protein anabolism is the process by which proteins ... Futile cycles occur when the catabolic and anabolic pathways are both in effect at the same time and rate for ...
A high-protein diet is a diet in which 20% or more of the total daily calories come from protein. [1] Many high protein diets are high in saturated fat and restrict intake of carbohydrates. [1] Example foods in a high-protein diet include lean beef, chicken or poultry, pork, salmon and tuna, eggs, and soy. [2]
Those chemical interactions also give rise to opioids' addictive effects. Vertex's drug works differently, blocking proteins that trigger pain signals that are later sent to the brain.
