Polyamine Compounds with many amino groups that are associated with nucleic acids. Related Terms: Nucleic acid A large molecule composed of nucleotide subunits.
[After the compounds are made]-often a dozen or so at a time-they then get sent to screening and they will be characterized for how tightly they bind. Oftentimes we're right that this one's the best one; this one's the worst one.
nucleosides - compound composed of a purine or pydimidine base linked to either a ribose or deoxyribose sugar. DNA and RNA are not polymers of nucleosides.
Hemiketal A compound formed by the reaction of a ketone group and a hydroxyl group; for example, the C-2 keto group of the open-chain form of fructose reacts with the C-5 hydroxyl group to form an intermolecular hemiketal.
When pH = pKa , the compound in question will have a charge of +0.5. E. When pH = pKa , the ionizable compound in question (whether acid or base) will be half protonated and half deprotonated.
A class of natural and synthetic compounds that inhibit the growth of or kill other microorganisms. (See Antibiotic resistance, Bacteriocide, Bacteriostat.) Antibiotic resistance.
"Photosynthesis - the synthesis by organisms of organic chemical compounds, esp. carbohydrates, from carbon dioxide using energy obtained from light rather than the oxidation of chemical compounds." ^ Katrina Edwards.

The pancreas (Figs. 1097, 1098) is a compound racemose gland, analogous in its structures to the salivary glands, though softer and less compactly arranged than those organs.
Substances were available to remove various organic compounds from bacteria, and if the remaining organic compounds were still able to cause R strain bacteria to transform then the substances removed couldn't be the carrier of genes.
The endoplasmic reticulum manufactures, processes, and transports a wide variety of biochemical compounds for use inside and outside of the cell.
In this method, rather than the painstaking, precise synthesis of a single compound at a time, biochemists deliberately mix a wide variety of reactants to produce an even wider variety of products - hundreds, ...
Chlorophyll is the magic compound that can grab that sunlight and start the whole process. Chlorophyll is actually quite a varied compound. There are four (4) types: a, b, c, and d.
Primary Producer: An autotrophic organism that makes complex organic compounds from inorganic compounds through the process of photosynthesis or chemosynthesis.
Molecules containing Carbon in their structures are called Organic compounds; for example, the Carbon Dioxide, which is formed by one atom of Carbon and two atoms of Oxygen (CO2).
Plants utilize CO2 as a "nutrient" to build more complex organic compounds. They add electrons and H+ (hydrogen ions) to form C6H12O6 (glucose and other molecules) for us and themselves.
Purine A nitrogen-containing, single-ring, basic compound that occurs in nucleic acids. The purines in DNA and RNA are adenine and guanine. Pyrimidine A nitrogen-containing, double-ring, basic compound that occurs in nucleic acids.
While using the newly invented compound microscope to look at a thin slice of cork, Hooke saw tiny room like structures that he named cells. The cells that Mr.

Such dideoxynucleotides can be added to a growing nucleic acid chain, but do not then present a 3' -OH group which can support further propagation of the nucleic acid chain. Thus such compounds are also called "chain terminators", ...
Sometimes a vacuole's function is to get rid of harmful toxins or to clear the extracellular space of those harmful toxins by bringing them into the cell for conversion; for chemical conversion into more safe compounds.
