One cup (121g) serving of split peas contains 54.2 mcg (micrograms) of vitamin K. That is 68 percent of the recommended dietary value for that vitamin.

Substitution of Val for Glu in the 6th amino acid may disrupt protein structure and function, as these amino acids have different properties. Valine is hydrophobic and bulky, while glutamic acid is hydrophilic and negatively charged. This change could impact protein folding, stability, and interactions with other molecules.

Arsenic has three electrons occupying the three 4p orbitals in its valence shell. Hund's first rule tells us that they will each occupy separate orbitals before they start to pair up. So there are three half-filled orbitals in an arsenic atom.

PEG-40 Hydrogenated Castor Oil is an ingredient commonly used in cosmetics and personal care products as an emulsifier and surfactant. It helps to blend oil-soluble and water-soluble ingredients together, allowing for a smoother texture and more stable formulation. It is derived from castor oil through a process called hydrogenation.

Fat has multiple definitions, but the scientific one would be dealing with biology since you used it as a noun. Lipids are another name for fats. A lipid are made of carbohydrates and proteins.

The Sakaguchi test is a chemical test used to detect the presence of arginine in a sample. It involves the formation of a colored dye complex when arginine reacts with ninhydrin in an acid medium. The intensity of the color produced is proportional to the amount of arginine present in the sample.

Lock and key is an analogy of enzyme catalysis in a cellular reaction. The lock and key are compared directly to the substrate and enzyme, because of the high specificity of their physical shape.

Enzymes participate in the reaction they catalyze.

The reactant molecule (substrate) binds to the enzyme molecule at a particular location called the active site. (this is compared to the lock with keyhole)

The highly specific nature of an enzyme is due to very precisely defined arrangement of atoms in the active site(again, this is the lock in the analogy). The substrate molecule must have a matching shape (here is the key) that will fit into the active site.

The bond breaking and bond forming processes that transform the substrate into products occur while the substrate is bound to the active site of enzyme.

In other words its something like a jigsaw puzzle where the substrate fits into the enzyme. The reaction occurs and the substrate then leaves the enzyme as products.

( Not my work. Found it on Yahoo Answers.....Do not give me credit...Thought I should do this to help people out =] )

Edited answer for readability and clarity - thanks!

peptide bonds -CONH-

the carboxylic group of one amino acid loses an OH group and the amino group of the other amino acid loses a H atom, eliminating a molecule of water for each peptide bond formed

Enzymes work by binding to specific molecules called substrates and catalyzing chemical reactions to convert them into different products. The enzyme's active site provides a specific environment for the reaction to occur, lowering the energy required for the reaction to take place. Enzymes are highly specific and can be regulated to control the rate of reactions within cells.

Renaturation is the opposite of denaturation for example in proteins. Basically in proteins if the polypeptide chain has been broken through denaturation, sometimes it is possible to be renatured or rebuilt to form the polypeptide chain.

An application of Avogadro's law is in determining the volume of a gas at different conditions of temperature and pressure. By knowing the number of moles of gas present and the initial and final conditions, Avogadro's law can be used to find the final volume. This is useful in various fields such as chemistry, physics, and engineering.

When benzoic acid reacts with barium hydroxide, it forms benzoate ions and barium benzoate. The balanced chemical equation for this reaction is: C6H5COOH + Ba(OH)2 → Ba(C6H5COO)2 + H2O. This is a double displacement reaction where the ions in the reactants switch partners to form new compounds.

Europium is the element named after the continent of Europe, which is in the Eastern Hemisphere. This element was discovered in 1896 by Eugène-Antole Demarçay. It has an atomic number of 63.

Yes, skin is flammable due to the presence of fats and oils on the surface. However, skin typically requires prolonged exposure to high heat for it to catch fire. It is important to exercise caution around open flames to avoid accidental burns.

The types of fermentation that occur in yeasts and some other microorganisms include alcoholic fermentation, where sugars are converted to ethanol and carbon dioxide, and lactic acid fermentation, where sugars are converted to lactic acid. Alcoholic fermentation is commonly used in baking and brewing, while lactic acid fermentation is used in the production of yogurt and sauerkraut.

In a localized bond, electrons are shared between two specific atoms, while in a delocalized bond, electrons are shared over multiple atoms or molecules. This delocalization leads to the formation of structures like resonance hybrids.

Turpentine is only soluble in organic solvents. However, it is insoluble in water since it is usually in form of oil.

Harry Griffin (1906-2004) was a British journalist and author known for his work in natural history, conservation, and countryside issues. He was the editor of the magazine Country Life and wrote numerous books on wildlife and the British countryside.

cell walls are semi-permeable, that is, they selectively permit only certain things through.

I recently had a blood test and my glucose level was 101 , it is supposed to be between 70-100. However dis does not indicate much for a possible diabetic. You really need to check for Hemoglobin A1C that has to be between 4.2-5.8

Glycolysis takes place in the cytosol or cytoplasmof the cell. The cytosol is the fluid compartment of the cytoplasm, outside the organelles such as the mitochondria and the nucleus. http://www.cellsalive.com/cells/membrane.htm http://www.biologyguide.net/resources/bk_14_08_2.htm

An acellular organism is one that lacks cells and is typically very simple in structure. These organisms, such as viruses and prions, do not have the typical organelles and structures found in cells. They also rely on host cells to replicate and carry out their biological functions.
