condensation
condensation reaction
When more than one atom is joined together by a chemical reaction, the result is called a chemical bond which holds together molecules and the strength of the bond depends on the atoms or the reaction. ---------------------------- A molecule.
Glucose is formed in photosynthesis when two molecules are joined together. These two molecules are ATP and CO2 (carbon dioxide).
In a condensation reaction two molecules are covalently bound and water (H2O) is generated. As a rule, one molecule releases an -OH and one gives up a -H in the reaction.
A molecule is when two atoms are bonded together. A compound is when two DIFFERENT atoms are bonded together. All compounds are molecules. Not all molecules are compounds.
This is a molecule.

the reaction in which glucose molecules are formed from starch is a Hydrolisis reaction
Three molecules of water are released when the four glucose molecules are joined.

None. Here we are talking of the synthesis of disaccharides. The biological mechanism entails the reaction known as "condensation", where two monosaccharide molecules, as glucose, join together to form a disaccharide. Condensation reaction involves the loss of a water molecule per two monosaccharides in a chemical reaction. Two OH groups, one from each sugar molecule, come together to release a water molecule and form an oxygen bridge between sugar molecules. One of the OH groups is attached to the anomeric carbon (the carbon that has 2 oxygens bonded to it).
A molecule is when two atoms are bonded together. A compound is when two DIFFERENT atoms are bonded together. All compounds are molecules. Not all molecules are compounds.
A hydroxyl group is removed from one molecule, a hydrogen atom from another molecule, and the two molecules are joined together to form a larger molecule. The OH and H combine together to form a water molecule. Therefore, dehydration synthesis involves removing a water molecule from two molecules (dehydration) in order to form a larger molecule (synthesis). This can be seen in many polymerization reactions, such as in forming a polypeptide from several amino acids. In this particular case, the OH is removed from the carboxyl group of one amino acid, and an H is removed from the amino group of another amino acid. The two amino acids are joined together in a dipeptide bond, and a water molecule is formed from the OH and H that were removed.
This is a molecule.
