Biochemistry

The OH on the end is slightly negative. Water is polar too, the hydrogens are positive and the oxygen is negative. Because both of the molecules have a net dipole movement (they have positive and negative ends) they attract each other and dissolve each other.

To make the ATP molecule, three phosphorus atoms must be removed from ADP (adenosine diphosphate) to form ATP (adenosine triphosphate). This removal of phosphorus atoms releases energy that can be used by the cell for various processes.

The representation H2O H plus plus OH signifies the dissociation of water molecules into hydronium ions (H+) and hydroxide ions (OH-) in aqueous solution. This is the auto-ionization of water where some water molecules act as both acids (donating H+ ions) and bases (accepting H+ ions). The concentration of H+ and OH- ions in pure water is equal at 10^-7 M.

The trypsin digest of the peptide Ala-Glu-Lys-Phe-Val-Cys-Tyr-Met-Gly-Phe would yield the following fragments: Ala-Glu-Lys, Phe-Val-Cys-Tyr, Met-Gly, Phe. Trypsin cleaves at the C-terminus of lysine and arginine residues, so the peptide is cleaved at the Lys residue.

Enzymes reduce the activation energy required for a chemical reaction to occur by stabilizing the transition state of the reaction. This allows the reaction to proceed more rapidly than if it were to occur without the enzyme present.

Mammalian enzymes are proteins found in mammals that catalyze chemical reactions in biological processes. They play important roles in digestion, metabolism, and other physiological functions by facilitating specific biochemical reactions within cells. Examples include amylase in saliva for breaking down carbohydrates and lipase in the pancreas for digesting fats.

Yes, monosaccharides are simple sugars that consist of a single sugar unit. They are the most basic form of carbohydrates and serve as the building blocks for more complex sugars and carbohydrates.

1. All organs in the body act differently chemically due to the presence of specific chemicals absorbed by the organ. This knowledge has helped develop diagnostic radiopharmaceuticals, to help examine the blood flow to the brain, functioning of the heart, lungs, liver functions, kidneys, excess growth of bones, etc. it also helps in predicting the effects of surgery and assess changes since the start of treatment. This non-invasive technology helps in observing the organ functions and diagnosing abnormalities without the patient experiencing any form of discomfort. The most widely used radioactive isotope is technetium-99m, that has the ability to disappear without a trace after completion of the test, in a short time. Thallium-201 chloride or technetium-99, is used in Myocardial Perfusion Imaging for detection and prognosis of coronary artery diseases.

When two amino acids come together, they form a dipeptide through a chemical reaction called a peptide bond. This bond joins the carboxyl group of one amino acid to the amino group of another, resulting in the loss of a water molecule in the process.

Amylase speeds up the breakdown of sucrose.

A U nucleotide is a type of ribonucleotide that is a component of RNA (ribonucleic acid). It stands for uracil, one of the four nucleobases found in RNA molecules, along with adenine, cytosine, and guanine. In RNA, uracil pairs with adenine during the process of transcription.

An amino acid is composed of an amino group (NH2), a carboxylic acid group (COOH), and a side chain (R group) attached to a central carbon atom. The specific structure of the side chain distinguishes different amino acids from each other.

When the linear form of glucose cyclizes, it forms a six-membered ring structure known as a hemiacetal. This ring structure is called a pyranose ring in the case of glucose and is commonly found in sugar molecules like glucose, fructose, and galactose.

This is most often used to describe the structure present in crustaceans. Their bodies are encased in a chitin exoskeleton. Chitin, the structural polysaccharide based on the monomer N-acetylglucosamine, is both flexible and strong, and is perfect to serve as the basis of their exoskeletons.

Transfer RNA (tRNA) can only bond to one specific type of amino acid through its anticodon region. This interaction ensures that the correct amino acid is delivered to the growing polypeptide chain during protein synthesis.

The electrons that chlorophyll loses to the electron transport chain are replenished by water molecules, which are split into oxygen, protons, and electrons during the light-dependent reactions of photosynthesis.

Facilitated diffusion is a type of passive transport that relies on carrier proteins to move specific molecules across the cell membrane. It does not require energy input from the cell and moves molecules down their concentration gradient. Facilitated diffusion is selective, allowing only specific molecules to cross the membrane based on their size and charge.

Do you mean, what is the application of a PET scanner? then... It is used mostly to detect heart/brain diseases and tumors, but is also used for many more things.

Amphibolism is the integration of catabolism(complex break down into small molecules) and anabolism(complex synthesized from small).Beta-oxidation of fatty acids by the liver is an example of amphibolism.

The production of a new fatty acid is called lipogenesis. It is a process where fatty acids are synthesized from acetyl-CoA and malonyl-CoA, which are precursors derived from carbohydrates and proteins. Lipogenesis occurs mainly in the liver and adipose tissue.

Jelly can contain glucose if it is made with added sugar. Glucose is a type of sugar that is often used in jelly recipes to help thicken the mixture and provide sweetness. However, some jellies may be made without added sugar and would not contain glucose.

Tris base refers to the compound tris(hydroxymethyl)aminomethane in its solid form, typically used to prepare Tris buffer solutions. Tris buffer, on the other hand, refers to a solution containing tris base that helps maintain a stable pH in biological and biochemical processes.

During interphase, the cell prepares for division by duplicating its DNA. In prophase, the nuclear membrane dissolves, and chromosomes condense. Metaphase is marked by the alignment of chromosomes at the cell's equator. Anaphase sees the sister chromatids separate and move to opposite poles, while telophase involves the reformation of nuclear envelopes. Lastly, cytokinesis divides the cytoplasm to form two new daughter cells.
