Proteins

Stable protein is a term that define the chemical or biophysical stability of a protein. Proteins are highly sensitive to pH, temperature and buffer environment(ions, metals). They are stable at optimal condition, change in one of these condition may cause them to precipitate or cause aggregates. Stable proteins are normally considered as active. Soluble proteins that are invisibly aggregated are not going to be stable to make its activity due to the structural change.

Proteins are often referred to as body building food because they play a vital role in building and repairing tissues in the body, including muscles. They are made up of amino acids, which are the building blocks of proteins. Consuming enough protein is important for muscle growth and overall body function.

Proteins are not a compound, but rather complex molecules made up of long chains of amino acids. A compound is a substance composed of two or more elements chemically bonded together. Proteins are organic macromolecules essential for various biological functions in living organisms.

Yes there is a turn over cycle happens for all proteins in cell. If a protein is not needed or a protein has done its job it will be degraded by proteases. Also the house keeping proteins are constantly made as they are needed for the cells primary activities.

No, it most be carefully note that all enzymes are mostly proteins and not all proteins are enzymes. Enzymes carry out the catalysis of biochemical reactions in and out of the cells. there are different non enzymatic structural and functional proteins they do have important roles such as hormones, structural proteins such as collagen etc.

All the proteins in the cells are made in ribosomes. After polypeptide synthesis they got matured and folded in ER, and Golgi bodies. There is no specific cells that only assembles proteins. All the cells of our body does it.

Proteins are synthesized by ribosomes in the cells by mRNA which codes the message of the amino acid sequence. Proteins found in diet is not going to directly act on our cells as they undergo digestion, only amino acids or other chemicals our cell gain. DNA in the nucleus controls the protein synthesis by gene expression.

Microtubules are not proteins themselves, but rather structures made up of protein subunits called tubulins. These tubulins assemble together to form long, hollow tubes that play a critical role in many cellular processes, including cell division and intracellular transport.

Protease enzyme is the general name given to enzymes that break proteins into amino acids. However, within that group, there are specific enzymes for specific proteins. An enzyme is considered a catalyst, a specific type of protein that speeds up reactions without being used up in the reaction itself.

Starch is found in plants as a energy store. They make simple sugars such as glucose when there is need of energy. Starch uses the protein beta amylase to be degraded in to simple sugar molecules.

Proteins that carry out enzymatic activity are known as enzymes. Enzymes can catalyze the conversion of substrate into the product. In digestion hydrolytic enzymes such as proteases, lipases, glycosidases such as amylase digest proteins, lipases, and carbohydrates respectively.

Proteins has two important role mainly, forming structure of cells or body and does the functional role such as enzymes, hormones, antibodies etc. Structural proteins such as collagen, keratin, actin, myosin build up the body. Enzymes catalyse the biochemical conversion of a substrate.

Proteins in the cells can be secreted out as intracellular proteins. Hormones, enzymes, and other proteins can be transported via blood stream and acts on distant tissues. when there is an injury or blood leakage appears in our hands lets say, proteins that does the blood clotting arrives there like a police to stop blood flow!

Yes, enzymes are typically proteins that act as biological catalysts to speed up chemical reactions in living organisms. They have specific shapes that allow them to bind to specific molecules and facilitate the conversion of substrates into products.

Yes, eggs are a terrific source of protein, as are meats.

Yes, cornflakes contain a small amount of protein. However, they are not a significant source of protein compared to other foods like meat, dairy, or legumes.

Yes, coffee beans do contain a small amount of protein, approximately 2-4% of their composition. However, most of the protein is lost during the roasting process. Therefore, brewed coffee typically contains minimal protein content.

Rh is a factor on blood cells that act as an antign (allergen) to those without it. The Rh refers to the fact that it was first found in Rhesus monkeys. If a mother is Rh negative (15% 0f the population in US) and her developing baby is Rh negative there is obviously no problem. If, however, the mother is negative and the baby is positive, the problem results. This only occurs when the father is Rh positive(+) and the mother is Rh negative(-). (lacking the Rh factor). The Rh factor passes the placental barrier, and the mother's immume system produces antibodies to the (+) factor. The antibodies pass the placental barrier also, and attacks the hemopoetic system on the baby (blood producing red marrow). As more a more red blood cells (RBC's)are destroyed by the antibodies, the blood system tries to increase the rate of cell production and starts sending immature RBC's in to the circulation. These are nucleated RBC known as Erythroblasts and the cells are not capable of transporting oxygen and carbon dioxide normally. The medical condition is known as "Erythroblastsis Fetalis" The inability of oxygen transport can lead to developmental anomalies and even death of the fetus. A Rh positive mother and either a Rh (+) baby or a Rh (-) baby have no problem. As with an allergic reaction, each subsequenial pregnancy causes greater allergic reaction. This can be prevented by the simple injection of a medicine (RhoGAM) to prevent the reaction ...sort of like an allergy injection.

One of the reasons for protein to be stable in buffer is the solubility of proteins. Protein forms in a way to display their hydrophilic amino acids to the surface and hydrophobic core with in the structure. hence the water molecule can interact with the polar amino acids of proteins.

No, peripheral proteins can face either the extracellular fluid (ECF) or the cytoplasm, depending on their function and interactions within the cell membrane.

Hormones can be proteins or steroids. Insulin and ACTH (adrenocorticotropic hormone) are proteins that are hormones, which are produced in the pancreas and the anterior pituitary gland, respectively. The hormones estrogen and testosterone are two examples of steroids that are hormones produced in the ovaries and testes, respectively.

Proteins carries both positively and negatively charged amino acids on them. so they are known as Amphoteric molecules that contain both charges (Zwitterions). An isoelectric pH or point is a pH where the net charge of the protein molecule is zero.

There is not something known called primary proteins. But proteins do have primary structure. Poly peptide chains after synthesized from ribosomes make up primary structure of a protein. this will afterward form 2D and 3D structure with additional structures and interactions.

Proteins are produced as polymer of amino acid chains. They gain secondary structure elements such as alpha helix, beta sheet during folding and for their three dimensional structure. Some proteins such as Hemoglobin make quaternary structure where they form the final structure with four different subunits of two different proteins interacting each other.
