Symptoms. In type 2 diabetes, many people have no symptoms at all. As type 2 diabetes is commonly (but not always) diagnosed at a later age, sometimes signs are dismissed as a part of âgetting olderâ. In some cases, by the time type 2 diabetes is diagnosed, the complications of diabetes may already be present.ymptoms. In type 2 diabetes, many people have no symptoms at all.

Sugar is made of covalent bonds between nonmetals-carbon, hydrogen and oxygen. It exhibits some classic properties of covalent compounds; it is a brittle solid, it has a relatively low melting point and is a poor conductor of heat and electricity.
These are usually simple molecules, unless a giant covalent structure is formed, which is rare. The simple covalent comounds have the following properties: Low melting points:- The bonds between molecules are very weak, especially when the molecules are small.It only requires a small quantity of heat energy to create enough molecular vibration to break the molecules attraction for one another and the solid melts.ow melting points:- The bonds between molecules are very weak, especially when the molecules are small.
