Covalent bonds are formed when two atoms are able to <em>share</em> electrons.
Iroinic bonds are form when two atoms are <em> </em> electrons from each other to complete the bond. This results in a pair of ions.
<u>Covalent bonds:</u>
- Have a definite shape.
- Have a low melting point.
- At room temperature they are in a liquid or gas.
- They occur between two non-metals.
<u>Ionic bonds:</u>
- Have no definite shape.
- Have a high melting point.
- At room temperature they are solid.
- They occur between a metal and a nonmetal.
Its is polar, meaning it has a positive and negetive end
Biosynthesis is a multi-step, enzyme-catalyzed process where substratesare converted into more complex products in living organisms. Examples of these biosyntheticpathways include the production of lipid membrane components and nucleotides. Biosynthesis is usually synonymous with anabolism.
