True Lean meats, poultry, fish, and eggs are the most concentrated source of protein. Many of these animal proteins are also good sources of iron and zinc.
protein metabolism is the metabolism of proteins
The endoplasmic reticulum (ER) is a flattened membrane that packages proteins. It plays a critical role in the synthesis, folding, and sorting of proteins. The ER consists of two main regions: the rough ER, which is studded with ribosomes and involved in protein synthesis, and the smooth ER, which lacks ribosomes and is involved in lipid metabolism and detoxification.
RNA is involved in the synthesis of proteins.
