Source of trypsin?

Trypsin is typically derived from the pancreas of animals such as cows or pigs. It is produced commercially through extraction and purification processes from the pancreas glands of these animals. Alternatively, trypsin can also be produced through recombinant DNA technology using genetically modified microorganisms.

PH range of pepsin?

pepsin is activated from pepsinogen in stomach. the pH range for its optimal ativity is at acidic pH between 1.5 to 2. It is also stable upto pH8 and can be inactivated at basic pH from 8.5,

Which monosaccharide is found in DNA?

Deoxiribose, this is a 15 year old answering this 4 the first time!

What elements are found to the right of the zigzag line on the periodic table?

Elements found to the right of the zigzag line on the periodic table are nonmetals such as nitrogen, oxygen, fluorine, and noble gases like helium and neon. These elements generally have properties like low melting points, poor conductivity, and tend to form negative ions in chemical reactions.

Why refrigerate urine?

The reason to refrigerate urine after collecting a sample is to avoid bacteria from forming in it. If a sample of urine will be taken to a lab within an hour of collecting it, then it does not need refrigerated.

What are catabolic plasmids?

Catabolic plasmids are a subclass of plasmids that carry genes encoding enzymes involved in the degradation of specific compounds, such as toxic chemicals or pollutants. These plasmids enable bacteria to break down and utilize these compounds for energy or nutrient sources. Catabolic plasmids play a crucial role in bioremediation by facilitating the degradation of environmental contaminants.

How much vitamin D do you need?

You need about 1.25 mg of vitamin D.
Ask your doctor, but 2000 I.U. is recommended for anyone with deficiencies or arthritis or difficulty with getting enough sunlight in wintertime. My sister takes even more at the direction of an herb doctor. 2000 I.U. is safe, and in time the recommended daily allowance will be increased closer to this amount, it is very low now. I am a former nurse also...

Types of compounds that use prefixes in their names are?

Some types of compounds that use prefixes in their names are covalent compounds, particularly binary covalent compounds formed between nonmetals. These prefixes indicate the number of atoms of each element present in the compound. Examples include carbon dioxide (CO2) and dinitrogen tetroxide (N2O4).

What does the Golgi Apparatus do in a plant cell?

In a plant cell, the Golgi apparatus is responsible for packaging and modifying proteins and lipids produced in the cell. It processes these molecules and prepares them for transport to other parts of the cell or for secretion outside of the cell. Additionally, the Golgi apparatus plays a role in synthesizing cell wall components and other plant-specific molecules.

KearnsSayre syndrome causes paralysis of the eye muscle difficulty in walking and heart prblems what is the connection between the symptoms and th role of mitochondia in cell function?

Kearns-Sayre syndrome is a rare neuromuscular disorder caused by abnormalities in the DNA of mitochondria, structures that drive cell function. This can cause problems with many of the organs and tissues in the body.

What occurs during the process of translation?

The sequence of nucleotide bases in an mRna molecule serves as instructions for the order in which amino acids should be and are joined together to produce a [polypeptide] protein.

The Cell uses a messenger Rna code to make proteins.

This is called The Genetic Code.


During the process of translation ,The cell uses information from mRNA to produce protein. This mRNA was produced through the process of transcription, which occurs in the nucleus of a eukaryotic cell.

How do different materials dissolved in water affect the surface tension of the water?

what types of materials? Dish soap and vegetable oil, I know for a fact, don't dissolve and separate the hydrogen bonds, causing a weaker surface tension. Salt does little to nothing (according to my chem and bio teacher). Sorry if any of this is wrong or not what you wanted.

What the basement membrane's function?

The basement membrane provides structural support and serves as a barrier between epithelial and connective tissues. It also plays a role in filtration and acts as a scaffold for cell migration during development and tissue repair. Additionally, the basement membrane helps regulate cell signaling and influences cell behavior.

How many peptide bond are present in the insulin molecule?

Look here for human insulin
http://www.uniprot.org/uniprot/P01308#section_features
The prepeptide is composed of 110 amino acids, from which are processed 2 chains, one composed of 30 amino acids and the other from 21. These are connected by disulfide bridges.

What do you need vitamins for?

Vitamins are essential nutrients that the body needs in small amounts to function properly. They play key roles in various bodily functions such as metabolism, immune system support, and overall health maintenance. Getting an adequate amount of vitamins through a balanced diet is important for overall well-being.

I am taking glutathione capsule 500 mg together with a 500 mg. Vitamin C as an ntioxidant but after 2 days i am having headaches can this possibly be the cause of my headache?

Depending on what you are using these products for, you should stop taking them for a bit, then start again on a lower dose.

What solvent can best dissolve Jasmonic acid?

It is best dissolved in DMSO but 100% ethanol also can be used.

What is the Protein buffer system?

Some of the side chains on the amino acids that make up the protein are weak acids, and some are weak bases. These can act as buffers (a buffer is a solution that contains a weak acid and its conjugate base, or a weak base and its conjugate acid).

What vitamins or minerals are essential to help memory loss?

There are different supplements that can help with memory loss. A study done last year by some researchers in MIT stated that Magnesium l-threonate helped with short term and long term memory.

Can vitamin b complex help depression?

Anything you do that increases your health will make you feel better. There are no vitamins or minerals which cure depression, but being healthy is a good start. When you're depressed, you don't take good care of yourself, and taking a good multi-vitamin is always a good idea. I'd recommend a complete formula, though, instead of just the B-vitamins.

Probably not. The last thing you need when you're depressed is another complex.

What electron carriers are produced in the Krebs cycle?

There are two electron carriers produced in the citric acid (Krebs Cycle). The first is NAD+ or NADH in its reduced form. The other is FAD+ which becomes FADH2 after being reduced. One turn of the citric acid cycle produces 1 and 3 molecules of FADH2 and NADH respectively.

What are the importance of enzymes?

Enzymes are biological catalysts that help speed up chemical reactions in your body. Without enzymes, our intestines would take forever to digest food, without enzymes our muscles and bones would not be able to move efficiently. Without enzymes we would die.
