Study Notes
Protein Functions
- Proteins provide structure to skin, bone, hair, and nails through collagen and keratin.
- Enzymes, a type of protein, catalyze virtually all reactions in living systems.
- Muscles are composed of proteins called myosin and actin, enabling movement.
- Hemoglobin, a protein, transports oxygen from the lungs to cells, while other proteins transport molecules across cell membranes.
- Many hormones, such as insulin, oxytocin, and human growth hormone, are proteins.
- The protein fibrinogen is involved in blood clotting, and antibodies, another type of protein, fight disease.
- Proteins like casein in milk and ovalbumin in eggs store nutrients for newborn infants and birds.
- Ferritin, a liver protein, stores iron.
- Certain proteins regulate gene expression and control when it takes place.
Protein Types
- There are two main types of proteins: fibrous proteins and globular proteins.
Amino Acids
- An amino acid is a compound containing both an amino group and a carboxyl group.
- In an α-amino acid, the amino group is located on the carbon adjacent to the carboxyl group.
