Biochemistry

Biochemistry is the study of the structure, composition and chemical processes in all living organisms. It covers the structures and functions of various cellular components, including proteins, carbohydrates, nucleic acids, lipids, and other biomolecules.

What happens to your heart when you have a bad diet?

A bad diet high in processed foods, unhealthy fats, and sugar can lead to heart problems such as high blood pressure, high cholesterol, inflammation, and plaque buildup in the arteries. This can increase the risk of heart disease, heart attacks, and strokes. It is important to maintain a balanced and nutritious diet to support heart health.

How does the body acquire carbon?

Carbon is the second most abundant atom in the body (the first is oxygen). All organic things are comprised of carbon. Now, taking as true the old maxim that matter cannot be created or destroyed, it follows that the body's primary source of carbon is food - after all, that's the only major organic matter entering the body. Since all organic (i.e. living) things are comprised of carbon, and our food is all from living matter (unless you happen to eat rocks, which I doubt), this means that our meals provide more or less all of our carbon intake.

What kind of atoms are vegetables made of?

Vegetables are primarily made out of carbon, nitrogen, hydrogen, and oxygen, like all living things.

They have a lot of magnesium (from chlorophyll), phosphorus (present in DNA and RNA), calcium, and various other elements as well.

Why glucose in soluble in protic solvent?

Due to formation of intermolecular hydrogen bonding.

Why is DNA evidence difficult to refute in court?

DNA evidence is difficult to refute in court because it is highly accurate and reliable. The technology used to analyze DNA is advanced and has a low margin of error, making it a strong piece of evidence. Additionally, DNA profiles are unique to each individual, making it highly improbable for someone else to have the exact same DNA profile.

Why does shrimp decompose?

Shrimp will not decompose while they are alive. All animals, once dead, start getting decomposed. This decomposition is the result of bacterial activity. Immunity protects the live animals from getting decomposed. Dead body is very good source of food for bacteria.Bacteria are present every where in organic sources.They are already present in intestine of shrimp. They multiply at enormous speed. With in 20 to 30 minutes they get double in number. You just try doubling them for two days.(means say 96 times and see the number.)(Just try 122*2.....96 times.) In absence of water, bacteria can not decompose the body of shrimp. So they are dried in sun light, in tropical countries, to preserve them for eating. They will not decompose, once you keep them in ice compartment of your fridge. Because enzymatic activity can not go on in ice. Enzymes can not move in solid ice. So dead body can remain without decomposing for thousands of years, in the ice on top of Himalayas.

Why is the ratio of C S KNO3 important?

If the ratio of carbon isn't correctly formed it will either burn too quickly or too slowly and if the correct ratio of sulphur (or sulfur for america) isn't represented it will burn too hot or cold and wont be as effective..

Why oxygen cannot be determined directly in combustion analysis?

Because it has impurities or it is mixed with other gases, such as CO2 (carbon dioxide), or it is in the form of water vapor.

What happens if salt is not taken?

Extra salt is not needed by your body, probably. You do not get the high blood pressure, when you do not eat the salt. In one tribal community, which was living in Central Africa and did not have access to slat, did not have high blood pressure. In tropical countries, you need to eat the extra salt. You loose the salt in your sweat, there.

Which tablet should not be taken when drunk?

There are many different drugs that should not be taken while drunk.

Any of the psychotropics should not be taken. These include, but are not limited to:

- benzodiazepines (Xanax, Valium, etc.)

- Ambien (and related drugs)

- barbiturates (Nembutal, Phenobarbital, Pentobarbital, Seconal, etc.)

- most antidepressants (side effects and complications of mixing alcohol with these drugs vary from person to person)

Why do they cellular respiration matter?

Cellular respiration is essential for producing the energy (in the form of ATP) that cells need to carry out their functions. It is the process by which cells break down glucose and other food molecules to release energy for metabolism. Without cellular respiration, cells would not have the energy needed to survive and function.

What is primary structure of a protein and what causes it?

Primary structure of the protein is simply its amino acid sequence. It is the sequence in which amino acids are added during protein synthesis.

What is enzyme turnover?

Enzyme turnover refers to the rate at which enzymes catalyze reactions, meaning how quickly they convert substrate molecules into products. This process involves enzymes binding to substrates, facilitating the reaction, and then releasing the products, allowing the enzyme to be available for further catalysis. Enzyme turnover is influenced by factors such as enzyme concentration, substrate concentration, and temperature.

What is the advantage of taking small amount of test substance?

The advantage of the same is that you can perform more number of tests with the same amount. But then, if you fail to conduct the test due to the amount being less, then it can become costly, instead.

A different enzyme controls each step of what?

A different enzyme controls each step of a metabolic pathway. This ensures that each chemical reaction in the pathway is tightly regulated and allows for efficient energy usage and production.

What pancreatic hormone promotes storage of organic fuels?

Insulin is the pancreatic hormone that promotes the storage of organic fuels, such as glucose, in the form of glycogen in the liver and muscle cells. It helps regulate blood sugar levels by facilitating the uptake of glucose from the bloodstream into cells for energy production or storage.

Is Valium water or fat soluble?

According to the manufacturing company, Diazepam (Valium) is a highly lipid-soluble benzodiazepine. Diazepam remains a popular oral drug for preoperative medication of adults.

The average protein contains 400 amino acids what is the maximum number of proteins that can be encoded by human genome?

The human genome contains approximately 20,000-25,000 protein-coding genes. Each gene can potentially encode multiple proteins through alternative splicing and post-translational modifications, so the exact number of distinct proteins that can be produced is much higher than the number of genes.

How enzymes are globular?

Besides fibrous proteins, that have only one type of secondary structure, globular proteins, including enzymes, transport and structural proteins, some peptide hormones, and immunoglobulins, are folded structures much more compact than alpha (helices) or beta (sheets) conformations.


Moreover, globular proteins, with random or repetitive conformations, have roughly spherical shapes. Globular proteins usually exhibit little or no change untill a point is reached at which there is a sudden drastic change and, invariably, a loss of biological function (e.g., structural proteins) or their enzymatic activity (for enzymes), a phenomenon known as denaturation.


Finally, to understand the terciary structure of globular proteins there are two powerful techniques to do it: X-ray or neutron diffraction analysis of single crystals, and NMR analysis (Nuclear Magnetic Resonance) of small proteins in solution.
