– N – C – group is characteristic of proteins because it has amino and

H O

The amino acids are the building blocks of the proteins. They are also the end‑products of the digestion of proteins.

Glycine is the smallest of the 20 amino acids commonly found in proteins. It is a colourless, sweet-tasting crystalline solid.

Secondary structure of protein is the general three-dimensional form of local segments of proteins. Secondary structure can be formally defined by the pattern of hydrogen bonds of the protein 9such as alpha helices or helix and beta sheets) that are observed in an atomic-resolution structure.

The isoelectric point or isoionic point is the pH at which the amino acid does not migrate in an electric field. This means it is the pH at which the amino acid is neutral i.e. the zwitterion form is dominant.

• Chemically heparin is mucoitin-polysulphuric acid.
• Mucoitin is a polysaccharide, composed of glucosamine, glucuronic acid esterified sulphuric acid.
• It is a potent natural anticoagulant produced in the Mast Cells that causes antithrombin bind to thrombin and produce inhibition of blood coagulation.

Starch common in plant and glycogen in animals are two food storage polysaccharides. Both of them can easily be hydrolysed into their glucose monomers.

Carbohydrates are the primary products of photosynthesis. They are the most important energy providing substrates for animals.
