What is the positive result and the importance of liebermann-burchard and salkowski tests?
The positive result of the Liebermann-Burchard test is a blue-green coloration, indicating the presence of cholesterol. This test is important for detecting the presence of cholesterol in biological samples, which can be indicative of certain diseases or conditions.
The positive result of the Salkowski test is the formation of a red color when testing for the presence of sterols, including cholesterol. This test is valuable in identifying the presence of sterols in samples such as plant extracts or microbiological cultures, aiding in research and diagnostic purposes.
How can you control your hormones?
try having every meal and try to make it a full and good one also take a break every now and then if needed Hormones.
a)Medical treatment: you can raise or lower
specific hormone values by specific medicaments.
b)By reducing your control area to your mindand intentional actions.
Involuntary reactions due to your hormonesare not caused by "you":
Though hormones also influence your mind you have good chances of
controlling actions that require the cooperation of your mind.
Describe in detail the pH scale for acids and bases?
the pH scale goes from 0 to 14. 0-3 is strong acid (eg. hydrochloric acid), 4-6 is not strong acid. 7 is neutral, eg. water. 8-10 is not strong alkali (base) and 11-14 is strong alkali (eg.sodium hydroxide)
Can Seliwanoff's test be used to distinguish sucrose from fructose?
Yes, fructose is a ketose, for which Seliwanoff's test is most sensitive. Sucrose is neither entirely a ketose nor an aldose, but is a mixture of both. It will react, but more slowly, producing a much lighter pinkish color.
heteropolysaccharides are composed of more than one monosaccharides and can contain chemical decorations (e.g. pyryvl, acetyl and succinyl). Succinoglycan is a simple example of heteropolysaccharide.
Ehrlich's test is a presumptive test for the presence of indole compounds, such as tryptophan, in a sample. It relies on the reaction between indole compounds and p-dimethylaminobenzaldehyde to produce a blue-colored complex. This test is commonly used in microbiology to detect the indole production by bacteria such as Escherichia coli.
What is the A340 value for NADH?
The millimolar extinction coefficient of NADH at 340 nm is approximately 6.22 mM-1 cm-1.
What is basic unit of protein?
The basic unit of protein is the amino acid. Proteins are made up of long chains of amino acids that are linked together by peptide bonds. Each amino acid has a unique side chain that contributes to the overall structure and function of the protein.
How will determine Molecular weight by Landsberger method?
we can determine the molecular weight from landsberger experiment for elevation of boiling point by using the formula
M2=(KBW2)*1000/T'W1
where M2=molecular mass
Kb=ebullioscopic constant or molal boiling point constant
W2=mass of solute
W1=mass of solvent
T'=change in temprature
Where is the Golgi apparatus located and what is its function?
It is situated in the cell of a plant or animal mostly towards the nucleus. The function of the gogli bodies is to transport proteins and enzymes synthesized by the ribosomes of the endoplasmic reticulum.
Hormone replacement therapy (HRT) is commonly used by some individuals who are crossdressers to help achieve a more feminine or masculine physical appearance that aligns with their gender expression. For male-to-female crossdressers, this may entail taking estrogen to promote breast growth and soften skin, among other changes. For female-to-male crossdressers, testosterone may be used to deepen the voice and promote more masculine physical characteristics. It's important to consult with a healthcare provider before starting any hormone regimen to ensure safety and effectiveness.
Purpose of carbon for living creatures?
Carbon is essential for living creatures because it is a key component of biological molecules such as carbohydrates, proteins, lipids, and nucleic acids. These molecules are crucial for various biological functions, including energy production, growth, and DNA replication. Carbon's ability to form diverse chemical bonds makes it the backbone of organic molecules, which are the building blocks of life.
Enzyme are proteins, and, thus, have the same building blocks. They are made up of amino acids.
One way to test for acids is to use litmus paper, which changes color in the presence of an acid. Another method is to use pH paper, which measures the pH level of a substance and indicates acidity. Lastly, you can perform a titration, where a solution of known concentration is used to determine the concentration of an acid.
Proteins are made from amino-acids and are assembled Via Ribosomes. RER [rough endoplasmic reticulum] contains Ribosomes while SER [smooth endoplasmic reticulum] does not.
They are synthesized by ribosomes which are found in the cytoplasm of a cell.
When a catecholamine or peptide hormone binds to receptors on the surface?
When a catecholamine or peptide hormone binds to receptors on the surface of a cell, it triggers a signaling cascade inside the cell that leads to various cellular responses. This can include changes in gene expression, activation of enzymes, alterations in cell metabolism, and modulation of cellular functions. Ultimately, these responses help the cell adapt to its environment and maintain homeostasis.
What test can be use to detect the presence of glycine?
fischer's method, zimmerman and klein and linser
If b vitamins make your urine yellow is the dosage too high?
Not necessarily. The color change in urine from B vitamins is harmless and does not indicate an issue with dosage. B vitamins are water-soluble, so excess amounts are usually excreted through urine, causing it to appear yellow.
Yes, enzymes can be reused multiple times because they are not consumed in the reactions they catalyze. However, their activity and efficiency might decrease over time due to factors like denaturation or loss of cofactors. Regular maintenance and optimization are typically needed to ensure their continued effectiveness.
In an equimolar mixture of alpha-D-glucose and beta-D-glucose, the percentage of alpha form would be 50% and the percentage of beta form would also be 50%.
Is casein positive to millon's test?
Yes, because casein is one of the protein that makes up milk. And when milk is denatured (by heat, or by any means), the denatured protein is tyrosine-which is the only protein positive for millon's test.
What are the best vitamins to take for a 57 year old?
At 57, it's important to focus on vitamins that support overall health and wellness. Consider taking a multivitamin that includes Vitamin D, Vitamin B12, Vitamin C, and Omega-3 fatty acids. It's always best to consult with a healthcare provider to determine the specific vitamins that would be beneficial based on your individual needs.
What amino acid causes sleepiness?
Tryptophan is an essential amino acid that has been referred to as a natural sleep aid. Tryptophan is a biochemical precursor to serotonin (a neurotransmitter) and melatonin. (a neurohormone). Both serotonin and melatonin are related to calmness and drowsiness.
What vitamin deficiency causes onion cravings?
Onions are fairly high in vitamin C and Magnesium.
However, some nutritionists don't believe that cravings can adequately express dietary deficiencies because most of us respond to foods because of their flavors or even emotional or mental association rather than their actual nutritional content.
In general, I find the website nutritiondata.com a good resource for these types of questions.
