Some of the most important functions of amino acids are as follows: 1. Building blocks of proteins Only L-amino acids are polymerized to form proteins, though both D-amino acids and non-L-amino acids found in nature. 2. Biological buffers Amino acids being amphoteric, act as buffers in solutions, resisting changes in pH. They do so by donating H+ ions as pH [...]
Amino Acids are the basic structural units (monomers) of proteins. Although over 300 different amino acids are known to occur in cells and tissues, only 20 of them universally occur in the proteins of all forms of life. These 20 amino acids are called protein amino acids or standard amino acids or magic 20. The others are called non-standard or [...]
Read this article to get information about Nucleic Acids, its structure, size, types and significance! These are important organic substances found in nucleus and cytoplasm. They control the important biosynthetic activities of the cell and carry hereditary information from generation to generation. Thus, nucleic acids are macromolecules of the utmost biological importance. They are associated with the chromosomes and transmit [...]
