Solution
The correct option is D Enzymes - Fibrous proteins
When the chains of polypeptides coil around to give a spherical shape, it is known as globular protein. This is usually soluble in water. Example of globular proteins are haemoglobin, albumin and insulin. A fibre like structure formed when polypeptide chains run parallel and are held together by hydrogen and disulphide bonds is known as fibrous protein. These proteins are usually insoluble in water. Examples are keratin and myosin.
The protein present in the hair is Keratin.
If the carboxyl acid group of glycine and amino group of alanine undergo elimination of a water molecule, the formed compound is glycylalanine (dipeptide).
Almost all enzymes are globular proteins, which are nothing but very long chains of amino acids residues (>100) and higher molecular mass, or polypeptides.
