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 is the source of cell autolysis?
Cell autolysis, or self-digestion of a cell by its own enzymes, can be triggered by a variety of factors such as cellular stress, infections, or genetic mutations. It can also occur as part of programmed cell death processes, like apoptosis or autophagy, where the cell actively breaks down its components for recycling.
Vitamins in cosmetic and haircare products typically cannot be absorbed through the skin and hair in sufficient amounts to provide health benefits. The molecules of these vitamins are usually too large to penetrate the skin barrier deeply. Instead, the vitamins in these products are intended to provide surface-level benefits such as moisturization and protection.
Chitin is a polysaccharide (polymer) of N-acetylglucosamine, which is a derivative of glucose.
It's chemical formula is: (C8H13O5N)n
...where "n" is the monomer length of the polymer.
Chitin is similar to the polymer cellulose in terms of function in biological organisms (primarily as a structural polymer), but has a completely different chemical structure.
What are the benfits of vitamin b50?
i can try to answer the question. it is basically a vitamin that has the regular B vitamins in a bit of a larger dose that gives energy release and so forth. the name is a publicity stunt to sell the product so don't get your hopes up on having 50 B vitamins in one tablet, for that matter there aren't that much B vitamins.
What was the contribution of democritus?
Democritus of Adbera was an ancient Greek philosopher, who conceived the idea that matter was made up of minuscule, irreducible particles, which he called atoms, a name derived from the Greek word atomos, meaning indivisible.) He said this about it:
"Nothing exists except atoms and empty space. Everything else is opinion"
Democritus' conception of the atom was, we now know, incorrect - the atom is not indivisible - but he was surprisingly close to the truth. However, being a philosopher and not a scientist, he never made any attempt to determine whether his theory was correct. As a result, although he is rightfully given credit as the first person to come up with this idea, he doesn't really deserve much more than that. In addition, Aristotle, one of the most highly respected Greek philosophers, hated the idea, and therefore it was forgotten until 1803, when John Dalton resuscitated the concept.
What is the role of modern chemistry to your daily life?
= What is role of chemistry in todays life = Absolutely nothing happens in life or any where else without chemicals and chemistry the role is is oly limited by the imagination and the laws of nature.
How HRESIMS identify a molecular formula?
High-resolution electrospray ionization mass spectrometry (HRESIMS) works by measuring the accurate mass of ions produced from a sample. By comparing the accurate mass of the ions with the mass of potential molecular formulas, HRESIMS can identify the most likely molecular formula based on the mass-to-charge ratio of the ions produced.
Definition of chemical disaster?
How much wine per day is it safe to drink?
Studies show that a glass of wine per day is just enough to consume. When drinking wine, especially red wine, it can reduce blood clotting, reduce production of low density lipoprotein cholesterol and boost the high density of lipoprotein cholesterol.
How does DNA and gel electrophoresis relate?
Gel electrophoresis separates an individual's DNA fragments from one another according to size. An electric current repels a mixture of the negatively-charged DNA fragments through microscopic pores in the gel from the negative to the positive electrode. Upon completion, the separated fragments of DNA can be visualized as a ladder of small bands in the gel by staining with a methylene blue dye solution or smaller DNA segments move more easily through the gel.
Three bananas a day, every day, is probably too much even for an adult.
Bananas are a good source of potassium but too much can upset the sodium and potassium balance in the blood, leading to irregular heart beat and potential cardiac arrest. The kidneys normally eliminate excess sodium or potassium to keep things in balance.
Banana.com says a 9-inch banana contains about 900 mg of potassium, or about 100 mg per inch. The University of Maryland Medical Center (http://www.umm.edu/altmed/articles/potassium-000320.htm) lists the recommended daily intakes of dietary potassium are:
- Infants birth to 6 months: 500
- Infants 7 months to 12 months: 700 mg or 18 Meg
- Children 1 year: 1,000 mg or 26 mEq
- Children 2 - 5 years: 1,400 mg or 36 mEq
- Children 6 - 9 years: 1,600 mg or 41 mEq
- Children over 10 years: 2,000 mg or 51 mEq
- Adult 2,000 mg or 51 Meq, including for pregnant and nursing women
Kjeldahl method for estimation of nitrogen in inorganic organic compound?
This is a very convenient method but its use is restricted.This method is suitable for estimating nitrogen in those organic compounds in which nitrogen is linked to carbon and hydrogen. The method is not used in the case of nitro, azo and azoxy compounds. The method is extensively used for estimated nitrogen in food, fertilizers and agricultural products.
Principle:- the method is based on the fact that when the nitrogenous compound is heated with concentrated sulphuric acid in presence of copper sulphate, the nitrogen present in the compound is quantitatively converted to ammonium sulphate. The ammonium sulphate so formed is decomposed with excess of alkali and the ammonia evolved is estimated volumetrically. The percentage of nitrogen is then calculated from the amount of ammonia.
Can low vitamin B12 cause severe joint pain?
Yes, low vitamin B12 levels can lead to nerve damage, which may result in symptoms like joint pain. It's important to address vitamin B12 deficiency promptly to prevent further complications. Consult a healthcare provider for proper diagnosis and treatment.
No, ice is not a macromolecule. Ice is a solid form of water, which is a simple compound made up of two hydrogen atoms bonded to one oxygen atom. Macromolecules are large molecules made up of smaller subunits called monomers.
What are the 5 scientific breakthroughs?

What is vitamin manufactured in skin?
Vitamin D has two forms which are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D without a subscript refers to either D2 or D3 or both.
Vitamin D3 is produced in the skin of vertebrates after exposure to ultraviolet B light.
Is cobalt chloride paper the same thing as pH paper?
No, cobalt chloride paper and pH paper are not the same. Cobalt chloride paper is used to test for the presence of water, while pH paper is used to test the acidity or alkalinity of a solution by measuring its pH level.
What kind of biological molecule is a dipeptide?
A dipeptide is a [protein] molecule that comprises [or is built from] two amino acids.
Carbohydrates are defined as what?
Carbohydrates are organic compounds with the general formula Cm(H20)n, that is, consisting only of carbon, hydrogen and oxygen, the last two in the 2:1 atom ratio.
It is also a major class of foods that includes sugars and starches.
If a subject's brain is showing a predominance of beta waves during a sleep experiment, it suggests that the subject is likely awake or in a state of alertness rather than being asleep. Beta waves are associated with active thinking, problem-solving, and alertness, characteristics not typically observed during sleep.
