acyl group enzyme

Lactose is made up of b -D-galactose and b -D-glucose held together by b (1 4) glycosidic bond. As the aldehyde group at C-1 position of glucose is free, lactose is known as reducing sugar. Lactose forms osazones. Lactose known as milk sugar is most important carbohydrate present in m..

. Copper is a cofactor of the enzyme cytochrome oxidase. Minerals take part in several biological processes. Iron serves as a prosthetic group for haemoglobin and is essential for the functioning of chlorophyll. Calcium plays a very important role in the clotting of blood. Some ..

There are saprophytic organisms (mainly bacteria and fungi) that live on dead animals and plants. In terrestrial ecosystem, bacteria act on animal tissue and fungi on plants but there may be exceptions also. This group of organisms plays a vital role in releasing back the biotic componen..

Photosynthetic phosphorylation or photophosphorylation is the process of phosphate group transfer into ADP to synthesize energy rich ATP molecule making use of light as external energy source. According to chemi osmotic hypothesis (Mitchell 1961) the ATP is synthesized on ATPase complexes..

Ribosomes are tiny ribonucleoprotein particles without a covering membrane. They serve as the site for protein synthesis. Hence, they are called protein factories of the cell. Each ribosome consists of larger and smaller subunits. The subunits of ribosome occur separately when ribosomes are not inv..

. The amino acid methionine is transferred from its tRNA onto the newly arrived proline tRNA complex where the two amino acids join by a peptide bond. The process is catalyzed by the enzyme peptidyl transferase located on the ribosome. In this process, the linkage between the first amino ..

Sucrose - Sucrose is made up of a -D-Glucose and b -D-fructose held together by a glycosidic bond, between C 1 of a -glucose and C 2 of b -fructose. The reducing groups of glucose and fructose are involved in glycosidic bond, so it is a non-reducing sugar. Haworth's Representation of Sucr..

(iv) On treatment with nitrous acid, primary amides give carboxylic acid and nitrogen gas. The volume of nitrogen can be measured to determine the amide quantitatively. The reaction involves molecular management in which alkyl or aryl group migrates from the acyl carbon to nitro..

. Separation of these additional phosphate groups from the nucleotides by enzymatic hydrolysis releases correspondingly large amount of energy. Hence, these higher nucleotides (with one or two additional phosphates) form energy rich compounds. Adenine + Pentose Sugar - Adenosine (Adenine ..

Biomolecules are complex organic molecules which built up living organism and form the basis of life. Biochemistry is the branch of chemistry which deals with the study of chemical composition and structure of living organism and chemical changes take place in them. Biochemical reactions li..
