Antibodies are proteins in the blood that fight disease.
The complement system is a group of small proteins helps or complent the antibodies or phagocytic cells to clear the pathogens. These small proteins generally circulating in blood plasma as an inactive form. complements are regulated by complement control proteins. complement caascade pathway activates various complement proteins.
Proteins
Pathogenic proteins are called prions.
No; antibodies cannot produce themselves.
proteins
Antibodies do not have a nucleus, because they are not cells. Antibodies are globulin proteins.
Simple the answer is an Antibody!
Antibodies attack proteins. If the organism starts to produce antibodies against the essencial proteins in metabolism (as seen in autoimune disease) it can lead to death
Proteins are labeled with radioactive amino acids so that they can be identified. Scientists use radioactivity to label proteins in order to track them during their experiments, you can follow protein degradation, label proteins that don't have antibodies, label all proteins produced at a certain time, separate proteins produced by intracellular pathogens from host proteins, among many other uses.
Globulins come in two forms; Immunoglobulins or Antibodies that attack foreign proteins and disease-causing organisms. The other is the transport proteins that carry small ions, hormones and other compounds, these can be LDLs and HDLs. Hope this answers your question, it came from my text book.Happy reading=)
I give a some important biological roles of proteins. Immunity-IgG or antibodies protecting us from pathogens. carrier proteins such as hemoglobin transport the oxygen molecule across all the cells for the respiration. structural proteins such as actin and myosin build the body. Functional proteins such as enzymes and hormones control the metabolism and pathways of the cell.
