Protein is a complex biomolecule that plays a vital role in nearly every aspect of our bodies.
Protein is a macronutrient composed of amino acids, which are the building blocks of protein.
It's a long chain of amino acids linked together by peptide bonds.
There are 20 different amino acids that the human body uses to build proteins.
Builds and repairs tissues (muscle, bone, skin, hair, etc.)
Produces enzymes, hormones, and other biomolecules.
Transports molecules and nutrients.
Regulates metabolism and energy production.
Maintains fluid balance and pH levels.
Supports immune function.
Structural proteins (e.g., collagen, keratin)
Enzyme proteins (e.g., lactase, protease)
Transport proteins (e.g., hemoglobin, lipoproteins)
Defense proteins (e.g., antibodies, interferons)
Storage proteins (e.g., casein, ovalbumin)
Animal products (meat, poultry, fish, eggs, dairy)
Plant-based sources (legumes, beans, lentils, tofu, tempeh)
