Proteins
Proteins are the macromolecules coded in our DNA that function as a biocatalyst and build our body. Apart from Biological knowledge, there are spectacular concepts in the field of proteins. How does a protein produce a function, how do they interact, how did they evolve and how do protein mutations cause disease.

What is the role of interleukin 2?
Interleukin-2 is a member of a large group of cytokines or growth factors with several roles. Some of the roles of Interleukin-2, or Thymocyte Stimulating Factor (also called: T-Cell Growth Factor), are: a) induces T-cell growth and proliferation; b) enhances natural killer cell activity; c) potentiates the release of gamma-interferon, B-cell growth factor, and B-cell differentiation factor; d) restores T-cell function in immunodeficiency disease states.
Biotech Interleukin-2 drugs are indicated to cancer immunotherapy, T-cell deficiency, various infectious diseases, including AIDS, and autoimmune diseases, including rheumatoid arthritis.
Are Proteins found in meat fish cheese and peas?
Meat, fish and cheese are the best sources of protein from the one's you mentioned in the question. They have great nutritional values, with fish probably having the best one's for a healthy, clean diet. Peas are also good, but they shouldn't be a main source of protein in your diet. They are of course great as a side dish and I would recommend everyone to take peas and other vegetables to be a part of a good, healthy diet. Peas also have a nice amount of fiber in them, which is a great thing!
Yes, all contain different types of proteins.
How do proteins play an important role in mating of japanese beetles?
by sending and detecting chemical messages
How are proteins assembled without DNA leaving the nucleus?
DNA indeed never leaves the nucleus. Instead, activated genes get transcribed by RNA polymerase, producing an RNA copy of the gene. The RNA gets processed (capped, spliced) and becomes a mature messenger RNA (mRNA).
The mRNA leaves the nucleus and sooner or later attaches to a ribosome. This will translate the information encoded in it into a protein.
Why antigens are made up of proteins?
They are made of proteins because the body has coded for them in that form. Usually genes code for proteins. This just the way the body works. Perhaps your question would have more information to ask for?
How do the side group of amino acids interact with each other and with other molecules?
Depending on what the side group(s) are, they can interact via hydrogen bonding, disulfide bond formation, dipole-dipole interactions, and dispersion forces.
Why are membrane proteins not water soluable?
They must be fat soluble so they can be in contact with the hydrophobic tails of the phospholipid bilayer.
Some are passive (e.g. melanin) and some are active (e.g. actin, myosin).
Rice are made up of mainly starch. Rice s a food storage of plant
Why we use reducing agent in protein extraction?
Reducing agents are used to reduce disulphide bonds (-S-S) present within (intrarmolecular) and between (intermolecular) the molecules. S-S bond is formed between two cysteine amino acid (one of the slphur containing amino acids, the other methionine can not form).
Reducing agents such as DTT, 2-mercaptoethanol are thus used in extraction buffer to kill the native protein structure.
Is renaturation of proteins possible?
If it is cooled it is possible.But denaturation due to heat cannot renaturized
Can lipase break down gelatin?
No, lipases are enzymes that digest lipids, i.e. glycerides or cholesterols, into smaller parts.
Gelatin is composed mostly collagen, which is a protein. Thus, to break down collagen you would need a protease.
Do mitochondria produce proteins?
Mitochondria do not produce proteins themselves, but they have their own genome and machinery to synthesize a few essential proteins. The majority of the proteins needed for mitochondrial function are produced in the cell's cytoplasm and then imported into the mitochondria.
Differences in r-groups give proteins different what?
Differences in R-groups give proteins different chemical properties, leading to variations in function, structure, and interactions with other molecules. These variations can impact the protein's role in biological processes and its overall behavior within a cell.
What do the antibody proteins do?
They bind to antigens, which can be either proteins, carbohydrates, or proteins decorated with attached carbohydrates. This allows the immune system to recognize infectious organisms and parasites so it can prepare to fight them.
Does proteins provide energy ture or false?
Yes they can provide energy. That happens when glucose level is low
How is the protein contained in seeds useful for the plant sprouting from the seed?
Seed storage proteins are proteins that are found in seeds. The main function of storage proteins is to be a storage reserve for nitrogen, carbon, and sulfur. These proteins are quickly mobilized during seed germination and serve as a source of reduced nitrogen for the growing seedlings.
they are complex macromolecules that carry out many functions in the body including: growth and repair, signaling from one cell to another, defense against invaders, and catalyzing chemical reactions. human bodies couldn't function without proteins
Proteins are important for many biological function in the cells. Proteins like collagen, actin, tubulin, myosin build up the body. Functional protein such as hormones, transporters, enzymes carry out many diverse role in cells.
