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.

Is gentiobiose a reducing or non-reducing sugar?

Gentiobiose is a non-reducing disaccharide because both of its reducing ends are involved in the glycosidic bond formation between the two glucose units. This means it does not have a free anomeric carbon available to reduce other substances.

Does vitamins help your body use carbohydrates?

Vitamins play a role in helping your body metabolize carbohydrates into energy. For example, B vitamins such as thiamine, riboflavin, and niacin are essential for converting carbohydrates into usable energy. Adequate vitamin intake is important for overall carbohydrate metabolism and energy production in the body.

What is name of hormone injections to gain quick weight?

One hormone injection commonly used to stimulate weight gain is called human growth hormone (HGH). It can increase muscle mass and fat storage in the body when administered in high doses, but its use for weight gain is not recommended due to potential health risks and side effects.

How would dry ice react when more dry ice is added?

When more dry ice is added to a container with existing dry ice, it will sublimate and create more carbon dioxide gas. This can cause an increase in pressure inside the container, potentially leading to a build-up of gas. It is important to handle dry ice with caution in a well-ventilated area to prevent any safety hazards.

What is the hormone antagonists of pth?

Calcitonin is an antagonist to PTH

C cells increase calcitonin secretion due to high blood Ca levels

PTH is secreted due to decrease in Ca level in blood Calcitonin allows osteoclasts to increase bone resorption when blood Ca level decreases.

What are conjugated proteins composed of?

Conjugated proteins are composed of a protein component and a non-protein component called a prosthetic group. The prosthetic group can be a lipid, carbohydrate, metal ion, or other organic molecule that is covalently bound to the protein. This non-protein component is essential for the biological function of the conjugated protein.

What fat soluble vitamin is found in dairy products oily fish and liver?

That is vitamin D. Unfortunately, the amount of vitamin D is very less, than you can guess, in dairy products. The amount is very high in fish liver oil, at times, the amount may be toxic.

MgSO4.7H2O is different from MgSO4?

MgSO4.7H2O, also known as magnesium sulfate heptahydrate, contains seven water molecules in its chemical structure, while MgSO4, also known as magnesium sulfate anhydrous, does not have any water molecules attached. This difference impacts the physical properties and behavior of the compounds when used in various applications.

What type of genetic recombination in bacteria involves DNA transfer by viruses?

Transduction is the type of genetic recombination in bacteria that involves DNA transfer by viruses. In this process, bacteriophages (viruses that infect bacteria) transfer bacterial DNA from one bacterium to another.

Why are lactate and ethanol formed under anaerobic conditions?

Short Answer: To regenerate NAD+ for the continued function of glycolysis.

Detailed Answer: As NADH is formed in glycolysis (2 NADH per glucose), NAD+ must be regenerated to allow continued glycolytic flux (and consequent production of ATP). In the presence of adequate oxygen (i.e. under aerobic conditions), this regeneration takes place predominantly in the mitochondria. Under anaerobic conditions, however, the only way to regenerate NAD+ is through lactate fermentation (e.g. mammals) or ethanol fermentation (e.g. yeast).

Why glucose and fructose form similar osazone crystals?

Glucose and fructose are both reducing sugars with a similar chemical structure, allowing them to react in a similar manner with phenylhydrazine to form osazone crystals. The reaction involves the same functional groups in both sugars, resulting in the formation of structurally similar osazones.

What are the short segments produced in the formation of the 3'-5' strand of DNA called?

During DNA replication, the lagging strand is replicated ~1000 (E. coli) base pairs at a time, forming numerous "Okazaki fragments".

Okazaki fragments form because polymerase is only able to replicate DNA in one direction, but DNA is double stranded, with the strands running anti parallel (in opposite directions). The polymerase waits for a region of DNA to be unwound, and while the leading strand is replicated continuously, on the lagging strand the polymerase waits until a region of single stranded DNA is produced before replicating it. This discontinous replication forms the Okazaki fragments, which can then be joined together by ligase (although a different polymerase enzyme, pol I in E. coli, is needed as well to replace the RNA primers with DNA).

What are the membrane-bound sacs the Golgi complex packs proteins and other materials into called?

The membrane-bound sacs in the Golgi complex are called vesicles. These vesicles transport and package proteins and other materials synthesized within the cell for storage or secretion.

What is Glycogen converted into when it leaver the liver?

Glycogen is converted into glucose when it leaves the liver. This glucose can then be released into the bloodstream to be used by other tissues in the body.

How prepare of cyanide with which reagents?

You mean you can use any reagent ...

Ok ... use ... CH3CONH2 + P2O5 ---> CH3CN

P2O5 is dehydrating

or

benzene + HNO3 + H2SO4 ---> C6H5-NO2 + Sn(HCl) ---> C6H5-NH2 + HNO2 (0 - 5degree celsius) ---> C6H5-N2Cl + CuCN ---> C6H5-CN

What are groups of Cells called?

Groups of cells are called tissues. Tissues are made up of a collection of cells that work together to perform a specific function in the body. Examples of tissues include muscle tissue, nerve tissue, and epithelial tissue.

Do archaebacteria have a cell wall composition?

Yes, archaebacteria have a unique cell wall composition compared to bacteria. Their cell walls lack peptidoglycan, which is a hallmark component of bacterial cell walls, and instead may contain other unique molecules such as pseudopeptidoglycan or S-layer proteins.

What is the hormone that makes the cervical mucus viscous?

Progesterone is the hormone that makes cervical mucus viscous, thick, and sticky, making it difficult for sperm to swim through the cervix. This helps prevent fertilization during certain times in a woman's menstrual cycle.

How is photosynthesis similar to C4 and CAM plants?

In C3 plants, photosynthesis occurs throughout the leaf, while in C4 plants, photosynthesis occurs in the inner cells. The photosynthesis in C3 plants is more efficient compared to the one in C4 plants.

What are the treatments for vitamin E deficiency?

Vitamin E deficiency in humans results in ataxia (poor muscle coordination with shaky movements), decreased sensation to vibration, lack of reflexes, and http://www.answers.com/topic/paralysis of eye muscles. One particularly severe symptom of vitamin E deficiency is the inability to walk.

What are symptoms of vitamin E deficiency?

The most common symptom of iron deficieny is fatigue (tiredness). Fatigue occurs because your body doesn't have enough red blood cells to carry oxygen to it's many parts. Deficieny of iron can also cause shortness of breat, dizziness, headache, coldness in one's hands and feet, pale skin and chest pain.

Which type of tissue is characterized by continuous loss and replacement?

Epithelial tissue is characterized by continuous loss and replacement due to the high rate of cell turnover. This tissue is found covering body surfaces and lining body cavities, where constant renewal is necessary to maintain function and protection.

What is produced from substrate level phosphorylation?

ATP is produced from substrate level phosphorylation during glycolysis and the citric acid cycle in cellular respiration.

Why is glycogen useful?

Glycogen is useful as a storage form of glucose in the body, particularly in the liver and muscles. It can be broken down quickly to provide a source of energy during times of high energy demand or low blood glucose levels. Glycogen also helps maintain blood glucose levels within a normal range and supports various physiological functions in the body.

Fermentation enables glycolysis to continue under what conditions?

Fermentation enables glycolysis to continue in the absence of oxygen, allowing for the regeneration of NAD+ to sustain ATP production. This process is particularly important in anaerobic conditions where aerobic respiration is not possible.
