Peptide Bond Formation A peptide bond  also termed as amide bond, is a covalent chemical bond formed when the carboxyl group of one molecule reacts with the amino group of the other molecule, which causes the release of a…

Protein molecules are important biomolecule in our cell system. The molecular weight of a typical protein molecule is comparable to the transfer RNA molecules. The average molecular weight of an…

Characterization of Amino acids and Proteins can be done using different techniques utilizing the information based on isoelectric point and net charge. Characterization-of-Amino-acids-and-Proteins I) Characterization of Amino acids and Proteins-Separation…

Titration curve of amino acids helps us to understand the ionization forms of amino acids at different pH. In this section we will see the titration curve of some amino…

Ionization of amino acids is important to understand that helps in clearing the concepts of pka, pI of monoprotic, diprotic and triprotic amino acids.. Amino acids are compounds that contain…

Nutritional Classification Nutritional classification is based on the availability of amino acids. Essential amino acids The amino acids which cannot be synthesized in the body must be supplied to the…

Chemical classification of amino acids can be considered as major basis of classification. The different chemical properties of amino acids are actually based on the properties of their R groups,…

The diversity of the thousands of proteins found in nature arises from the intrinsic properties of only 20 commonly occurring amino acids. These features include: (i) The capacity to polymerize,…

Amino acids are the building blocks of proteins, and can be metabolized to produce energy. Amino acids are especially important at the time of fasting, when the breakdown of muscle…
