The following points highlight the four structure types of proteins. The types are: 1. Primary Structure 2. Secondary Structure 3. Tertiary Structure 4. Quaternary Structure. Type # 1. Primary Structure: Peptide bond is formed by the amino acids linked by carboxyl group of one amino acid with the α-amino group of another amino acid as shown: H2N-CH2-CO-NH-CH2-COOH Glycyl-Glycine Thus, they [...]
In this article we will discuss about the Mechanism of Protein Synthesis in Prokaryotes and Eukaryotes. Protein synthesis in the cell is conducted by ribosomes that are found attached to the membrane of endoplasmic reticulum and microsomes, as well as in free state in the groundplasm. The main components that take part in protein synthesis at cellular level are: 20 [...]
In this article we will discuss about the composition and structure of proteins. Composition of Proteins: Proteins are large molecules consisting of many amino-acids connected by "peptide linkages". Peptide bond is produced when carboxyl radical of one amino acid reacts with the amino (-NH2) group of the other amino acid. The basic structural formula of amino acids is shown in [...]
