In a polypeptide or a protein, amino acids are linked by a peptide bond which is formed when the carboxyl (-COOH) group of one amino acid reacts with the amino (-NH2) group of the next amino acid with theelimination of a water moiety (the process is called dehydration). In polysaccharide the individual monosaccharides are linked by a glycosidic bond. This bond is also formed by dehydration.

Many secondary plant products are of great use in commerce in making drug and perfumes. The primary product of plants is carbohydrates synthesized during photosynthesis.

Fevicol is a synthetic sticky substance insoluble in water and used for joining wood and paper is a type of resins.

The amino acids are linked together one after the other by peptide bonds. This bond is formed between NH3 of one amino acids with carboxyl end of another amino acids to release water.

The most important form of energy currency in living systems is the bond energy in a chemical called ATP.

The blood concentration of glucose in a normal healthy individual is 4.5-5.0 mM.

Chemical compounds undergo two types of changes. A physical change simply refers to a change in shape without breaking of bonds.This is a physical process.

Adenosine triphosphate (ATP) is a nucleotide. Nucleotide is formed by pentose sugar, nitrogenous base and phosphates. Many nucleotidejoins together to form polynucleotide.

Enzymes are bio-catalyst that alter the rate of biochemical reactions in living organisms. The part of enzyme where catalytic work is carried out is called active site.
