    Study Notes

    Partially Complete Proteins

    • Some animal proteins contain lower levels of essential amino acids, making them insufficient for body growth.
    • Examples include certain fish that have a small amount of methionine, an essential amino acid.

    Incomplete Proteins

    • Incomplete proteins lack one or more essential amino acids.
    • Typically found in plant sources, such as grains and cereals.
    • Combining different plant proteins creates a balanced diet through complementary proteins.
    • Mixing animal proteins with plant proteins also provides a complete amino acid profile.

    Functions of Protein

    • Essential for tissue building and repair processes.
    • Serves as a source of energy for the body.
    • Crucial for growth and development.
    • Contributes to plasma proteins, like albumin, vital for maintaining osmotic balance in body fluids.
    • Plays a significant role in the body's defense system through antibodies.
