Learn the definition of a chemical bond. Discover the three types of chemical bonds, see examples of each, and understand when the different types...
Types of Chemical Bonds:The matter is made up of the same or different kinds of elements. Under normal conditions, no other element exists as an independent atom in nature, except noble gases. Instead, atoms of the same or different kinds of elements combine to form molecules. Molecules are ...
MicroRNAs (miRNAs, miR), circulating in the bloodstream, are viewed as indicators of the fundamental disease processes occurring in atrial fibrillation (AF). However, miRNA levels in peripheral blood samples might not represent a cardiac occurrence, since these molecules have a broad range of ...

A chemical reaction is a process in which the chemical structure of a substance changes, leading to the formation of a new substance with different properties. In other words,the reactantsconvert intoproductsthrough the breaking and formation ofchemical bonds. ...

Proteins are biological polymers constructed from amino acids joined together to form peptides. These peptide subunits may bond with other peptides to form more complex structures. Multiple types of chemical bonds hold proteins together and bind them to other molecules. Take a closer look at theche...
As a result of this change in the number ofelectronsin the outermost shells ofatoms, bonds are formed betweenatomsor bonds are broken to form new bonds, this is calleda chemical reaction,Chemical reaction is the breaking of bonds betweenatomsof the reactants molecules to form new bonds betw...
Erythro and threo are two configurations in which molecules are written when the molecules have a chiral carbon atom. Erythro is the configuration when the same groups are on the same side of the carbon atom and Threo is the configuration when the same groups are on the opposite side of the...
Each of the types of reactions involves an overall energy change as well as the rearrangement of atoms/molecules. The rearrangement creates the products of the reaction. The product(s) are found to the right of the arrow in a chemical reaction formula. A chemical reaction occurs when a chemic...
