rajibray What is homeostasis? The composition of the internal environment is maintained within narrow limits, and this fairly constant state is called homeostasis. Literally, this term means ‘unchanging’, but in practice, it describes a dynamic, ever-changing situation kept within narrow limits. When this balance is threatened or lost, there is a serious risk to the well-being … Read more
Levels of structural complexity: There are various degrees of structural complexity and organization within the body. Chemicals are at the lowest level. The body has a wide variety of molecules, which are created when two atoms unite. The body contains millions of cells, the smallest autonomous units of living matter. They cannot be seen with … Read more
The liver is the second largest organ in the body. The liver is the only body organ that can regenerate. The liver is responsible for more than 500 body functions. Liver functions Cleanses your blood Regulates the supply of body fuel. Produces essential body proteins. Regulates the balance of hormones. Regulates body cholesterol. Produces bile … Read more
What is diabetic neuropathy? Diabetic neuropathy pain: Diabetic neuropathy is nerve damage caused by diabetes. The most common of these is nerve damage in the feet and hands. This kind of nerve damage can lead to different kinds of symptoms, such as numbness or lack of muscle control burning or tingling pain, burning, and extremely … Read more
Conditions for optical activity : The two aryl groups’ planes must not be plane. Bulky groups are positioned in the ortho locations to achieve it. (ii) In most cases, the enantiomers can be resolved. (iii) Ortho substituents increase the restricted rotation by their steric repulsion. (iv) Mono ortho-substituted biaryl compounds do not show atropisomerism at … Read more
Conformational isomerism: These are the isomers formed when single bonds in the molecule are rotated. Through additional rotation around single bonds, they might be quickly interconverted back to one another. One conformer must be transformed into another by overcoming a rotating energy barrier. Some important examples of conformational isomerism include:(i) Open chain alkane conformations: Staggered, … Read more
Geometrical isomerism: The molecular formulas of fumaric acid (m.p. 287 °C) and maleic acid (m.p. 130 °C) are identical, but the configuration of functional groups surrounding the double bond varies. They differ in terms of their physical and, to some degree, chemical characteristics. This type of isomerism is known as geometrical isomerism. The methods of … Read more

Asymmetric synthesis (partial and absolute) Asymmetric synthesis: De novo conflation of a chiral substance from an achiral precursor similar that one enantiomer predominates over the other is called asymmetric conflation. For responses where motes formerly contain a chiral element and conflation introduces a new chiral element, conflation is appertained to as’ stereoselective or enantioselective’ conflation … Read more
Physiology of the Heart: At any given time, the chambers of the heart may be found in one of two states: Systole: During systole, cardiac muscle tissue contracts to push blood out of the chamber. Diastole: During diastole, the cardiac muscle cells relax to allow the chamber to fill with blood.Blood pressure increases in the … Read more
