The difference between first class and second class proteins lies in their amino acid profile. First class proteins, also known as complete proteins, contain all essential amino acids in sufficient quantities for human needs. Examples include animal proteins like meat, fish, eggs, and dairy. Second-class proteins, known as incomplete proteins, lack one or more essential amino acids. These are typically plant-based proteins like legumes, grains, nuts, and seeds.
