A Biomolecule can be defined as any molecule generally formed by a living organism. It mainly includes macromolecules and micro molecules. The best example for large molecules are Proteins, Nucleic acids, Lipids and Polysaccharides and small molecules such as natural products, Primary and secondary metabolites. Biomolecules are also known as biogenic substances. Synthetic analogs are defined as the artificial compounds differing from the natural compounds in their structure, resemblance and function. Synthetic refers to any material made from non-natural sources. This means that a product such as cloth is made from a chemical source rather than the fibers produced by nature. Biomolecules and their synthetic analogs play vital role in medicine, drug delivery or antiviral agents etc. Most analogues are designed because ""true synthetic"" natural products are hard to make, or are not potent enough. For instance, morphine is poorly absorbed and of only moderate potency, but if it is converted into hydromorphone or heroin (analogues) it gains potency and can be more completely absorbed (in the case of some morphine esters). However all the classical opiates are very hard to make in laboratories, so drugs like pethidine, methadone, abd fentanyl were devloped that are much easier to make and are not dependent on opium poppy production. In Pharmacology Analog is referred as Functional analog, and structural analog; A chemical compound with similar properties to another is a Functional analog. Structural analog is a chemical compound with a slightly altered chemical structure compared to another.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
