Question

What are properties of protein???!​

Answer 1

Answer:

The common property of all proteins is that they consist of long chains of α-amino (alpha amino) acids. The general structure of α-amino acids is shown in . The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group (―NH2); the α-carbon atom also carries a carboxyl group (―COOH).

Answer 2

Answer: The physical properties of proteins are:

1. Proteins are colourless and usually tasteless. These are homogeneous and crystalline.

2. The proteins range in size from simple crystalloid spherical structures to long fibrillar structures. Two disctinct patterns of shape has been recognized:

                                     a. Globular proteins.

                                     b. Fibrillar proteins.

3. The proteins generally have large molecular weights ranging between 5×103 and 1×106.

4. Because of their giant size, the proteins exhibit many colloidal properties, such as: Their diffusion rates are extrememly slow and they may produce considerable light- scattering in solution, thus resulting in visible turbidity.

5. Like amino acids, proteins are amphoteric, i.e., they act as both acids and alkalis.

6. The proteins can form salts with both cations and anions based on their net charge.
