In this article we will discuss about the various structures of proteins. This will also help you to draw the structure and diagram of proteins. Proteins consist of long polypeptide chains and we know how to determine the sequence of the amino acids of these chains. This constitutes the primary structure of proteins. But in reality, each protein has a [...]
In this article we will discuss about the physical and chemical properties of amino acids. Important Physical Properties of Amino Acids: 1. Optical Isomerism: All amino acids, except glycine which has two H atoms on the α-carbon, have an asymmetric α-carbon (the 4 valence bonds are attached to different atoms or groups). As may be seen in figure 1-1, one [...]
In this article we will discuss about the two main types of amino acids, i.e, alphatic amino acids and cyclic amino acids. 1. Aliphatic Amino Acids: A. Hydrocarbon Chain Amino Acids: 1) Glycine (Gly) or glycocoll, or α-aminoacetic acid is the simplest of the amino acids because R = H: Glycine is very widely distributed in proteins; it is particularly [...]
