Study Notes
Composition of Proteins
- Proteins are made up of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur and phosphorus.
Collagen Function
- The main function of collagen is to provide structure and strength to connective tissue, such as skin, bones, and tendons.
Regulation of Fluid Balance
- Proteins that help regulate fluid balance in the body are albumin and globulin.
Immune Response
- Proteins that attack and inactivate bacteria and viruses in the blood are immunoglobulins (antibodies).
Enzymatic Function
- Enzymes catalyze chemical reactions in the body, breaking down nutrients into energy and aiding in digestion.
Hormone Function
- Hormones act as chemical messengers, regulating various bodily functions such as growth, development, and metabolism.
Protein Catabolism
- When the body is under severe stress, starving, or in a catabolic state, it breaks down its own protein for energy.
Iron Regulation
- Transferrin regulates iron levels in the body by binding to excess iron and transporting it to storage sites.
Lipoprotein Composition
- The main components of lipoproteins are triglycerides, phospholipids, and proteins (apolipoproteins).
Acid-Base Balance
- Proteins contribute to acid-base balance in the body by buffering excess hydrogen ions.
Antibody Function
- The main role of antibodies is to recognize and bind to specific antigens, marking them for destruction by other immune cells.
Albumin Function
- The primary function of albumin is to regulate osmotic pressure, maintain blood volume, and transport nutrients and hormones.
