Biological Nitrogen Fixation: Controlling Factors

The following points highlight the four factors controlling the biological nitrogen fixation. The factors are: 1. Environmental Factor 2. Stage of Plant Growth 3. Fertilizers in the Soil and 4. Genetic Factors. Factor # 1. Environmental Factor: Usually, the factors which favour photosynthesis such as adequate moisture, warm tem­peratures, bright sunlight and higher CO2 levels, also enhance biological nitrogen fixation. [...]

Biosynthesis of Amino Acids: 3 Ways

Biosynthesis of amino acids. The ways are: 1. Ammonium Assimilation 2. Transamination and 3. Other Methods. Way # 1. Ammonium Assimilation: (A) Reductive Ammination: Inorganic nitrogen in the form of NH3 or ammonium (NH4+) produced as a result of reduction of nitrates or biological nitrogen fixation or obtained from the soil, react with a-ketoglutaric acid (an intermediate of Krebs' Cycle) [...]

Proteins: Structure and Classification (With Diagram)

Let us make an in-depth study of the proteins. After reading this article you will learn about 1. Structure of the Proteins and 2. Classification of Proteins. Proteins: Proteins are organic nitrogenous compounds in which a large number of amino acids are joined together by peptide linkages to form long polypeptide chains. Peptide-linkage (—CONH—) is formed when amino group (—NH2) [...]
