In this article, we will discuss about the nucleoside and nucleotide. A nucleoside is composed of two components: (a) Nitrogenous base and (b) Five-carbon sugar (pentose). 1. Nitrogenous bases: The nitrogenous bases are derivatives of two parent heterocyclic compounds, i.e., purine and pyrimidine. 2. Pentose Sugars: The pentose sugar present in the nucleic acids is ribose in RNA and deoxyribose [...]
The following points highlight the three types of ribonucleic acid (RNA). The three types are: 1. Messenger RNA (mRNA) 2. Transfer RNA (tRNA) and 3. Ribosomal RNA (rRNA). RNA Type # 1. Messenger RNA (mRNA): It carries the genetic message from the chromosomes (DNA) to the ribosome (site of protein synthesis). This RNA is formed in the nucleus (or nuclear [...]
The following points highlight the two types of fatty acids. They are: (1) Saturated Fatty Acids and (2) Unsaturated Fatty Acids. Fatty Acid Type # 1. Saturated Fatty Acids: These fatty acids contain only single bonds along the length of the carbon chain, i.e., all the carbon atoms are fully saturated with hydrogen atoms. The fatty acids found in the [...]
