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.

8,065 Questions

Are oils soluble in water?

No, most oil is not soluble in water. Oil is hydrophobic, or "water fearing."

This goes for all lipids.

There are some water miscible oils but they are rare and typically only used in very specialty situations.

Which lipid will give a single molecule of fatty acid when hydrolyzed?

A triglyceride will give a single molecule of fatty acid when hydrolyzed through the process of lipolysis. Triglycerides consist of three fatty acid molecules attached to a glycerol molecule. Upon hydrolysis, one fatty acid is released along with glycerol.

TCA cycle is Amphibolic in nature-Why?

In aerobic organisms the TCA is amphibolic pathway, one that both srves in the catabolic and anabolic processes. besides its role in the oxidative catabolism of carbohydrates, fatty acids and amino acids, the cycle provides precursors for many biosynthetic pathways

Are nucleic acids polymers of nucleotides?

Yes, they are. Nucleic acid polymeric subunits of ribonucleotides condense to form Rna, while polymeric subunits of 2' [two prime] -deoxy-Rna condense to form Dna.

So tough to explain such a small difference between Rna and Dna!

Disaccharides are broken down into their component monosaccharides by.?

The decomposition of any nutrient is called hydrolysis, in which a molecule of water is broken and "caps" the ends of the two monomers. The opposite of hydrolysis is called a condensation (or dehydration) reaction.

Are beans the world's healthiest food?

Beans are highly nutritious and offer many health benefits, including being a good source of protein, fiber, and antioxidants. While they are a healthy food choice, it's important to have a balanced diet that includes a variety of nutrient-rich foods.

What are DNA stuffer regions?

In a bacteriophage that's been modified as a vector for DNA cloning, a "stuffer region" is a sequence of useless DNA that can be removed with specific endonucleases, to prepare a site for insertion of the DNA to be cloned (sometimes called "passenger DNA" - the idea being that the phage is the vehicle).

If you burn a candle will there be carbon dioxide?

The flame will go out, because carbon dioxide removes the oxygen from the area surrounding the flame. Fire requires oxygen to burn, much like humans need oxygen to breath, and similar to carbon dioxide does to humans, the flame will lose its oxygen and go out.

How is the enzyme catalyze influenced by pH?

Enzyme catalysis is influenced by pH because enzymes have an optimal pH at which they function most effectively, often corresponding to the pH of their normal working environment. Changes in pH can disrupt the charge distribution on the enzyme's active site, affecting its ability to bind to the substrate and catalyze the reaction. Extreme pH levels can denature enzymes by altering their structure, leading to loss of function.

What are the Difference between orbit and orbitals?

Orbitals are 3D while orbits are 2D

Orbitals determine the most probable location where the electron pairs are found

Orbits determine the energy level of the electrons

Orbits can only contain a maximum of 2 electrons

Orbitals can contain 2n^2 electrons

  • Orbit is a concept from celestial mechanics and astronomy.
  • Orbital is a concept from quantum mechanics, spectrometry, and chemistry.

Why are babies prone to Vitamin A deficiency in poor countries?

It is related to the dietary deficiency. Vitamin A is supplemented to the body through dietary sources, including milk, liver, butter, cheese, eggs, and fish liver oils, or as carotenoids from fruits and vegetables. The rate of vitamin A rises in countries suffering poverty and hunger.

What is the best way to raise Vitamin D?

To raise the level of Vitamin D, you should go outside in the sun more (using sunscreen to avoid being burned) and/or take a natural supplement that contains Vitamin D.

More information:

Giving calcitriol, or its analogs, for vitamin D deficiency is like shooting ether into your engine to keep your car running. In addition, they pose a significant risk of hypercalcemia (high blood calcium). If you have a simple vitamin D deficiency and your doctor insists on prescribing calcitriol or an expensive analog of vitamin D (other than cholecalciferol or ergocalciferol), find another doctor.

Hypersensitivity Not ToxicityVitamin D hypersensitivity syndromes are often mistaken for vitamin D toxicity. This rare syndrome occurs when abnormal tissue subvert the kidney's normal regulation of endocrine 1,25(OH)2D3 (calcitriol) production. Aberrant tissues, usually granulomatous in nature, convert 25(OH)D into 1,25(OH)2D3 causing high blood calcium. The most common of such conditions are sarcoidosis, oat cell carcinoma of the lung, and non-Hodgkin's lymphoma-although other illness, such as primary hyperparathyroidism, can cause the syndrome. Periodic measurements of 25(OH)D levels and serum calcium will alert the physician to the need to do more tests, such as 1,25(OH)2D3 or PTH.

Toxicity is simply not a concern in doses below 10,000 units a day.

What is a salt cut in protein purification?

A salt cut in protein purification is a process to reduce the concentration of salt ions in solution. This is generally done by adding a determined amount of a solution with a lower amount of salt to the sample in order to achieve an specific salt. This is typically done before an ion exchange step.

What is the definition of recalcitrant organic compounds?

Recalcitrant compounds, either organic or synthetic that are resistant to being broken down through chemical processes. And therefore are treated using microbes to help with the process of degrading the recalcitrant compounds into smaller, more manageable compounds.

What b vitamin helps make new cells?

The B vitamin that helps to make new cells is called folate. It is also needed for the construction of DNA and is the most needed prenatal vitamin.

What is oxygen consumed in breathing is converted to?

Oxygen consumed in breathing is converted to carbon dioxide during cellular respiration. This process takes place in the mitochondria of cells and produces energy in the form of adenosine triphosphate (ATP) that can be used by the body.

What are some similarities of DNA and RNA?

tRNAs are small RNA molecules that carry amino acids to growing polypeptide chains that are being made in a ribosome. The have anti-codons that are complimentary to the codons on the mRNA. They carry an amino acid that is specific to their anti-codon.

mRNA is an RNA copy of a gene in the DNA that sends instruction for making a protein to the cytoplasm from the nucleus.

Nutritionists suggest that no more than percent of your daily calories should come from fat?

Nutritionists suggest that no more than 20-35% of your daily calories should come from fat. Consuming excess fat can lead to weight gain and various health issues such as heart disease. It is important to choose healthy fats from sources like avocados, nuts, and olive oil to meet this recommendation.

Is the energy from sunlight trapped by chlorophyll located in the electron transport chain?

No, the energy trapped by chlorophyll is located in photosystem I and II. Light energy is first captured by PS II and an electron is then transferred to a primary electron acceptor known as plastoquinone. Pq then transfers it's electron to the cytochrome complex that transfers its energy to the electron transport system which passes it on to plastocyanin which in turn gives its electron to PS I where it is re-excited by photons. This process is known as the electron transport but the energy captured by chlorophyll is located in the photosystems.

Cholesterol belongs to what class of organic compounds?

Cholesterol belongs to the lipid group of macromolecules and is a member of the group of sterols.

The main functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. "Lipid" is sometimes used as a synonym for fats.

How are nucleic acids held together?

Nucleic acids are held together by phosphodiester bonds between the sugar and phosphate groups of adjacent nucleotides in the backbone of the molecule. Additionally, hydrogen bonds between nitrogenous bases in complementary strands help stabilize the double-stranded structure of DNA or RNA.
