What is Omega-3 Fatty Acid? Definition of Omega-3 Fatty Acid Omega-3 fatty acids are essential polyunsaturated fatty acids (PUFAs) characterized by a double bond three atoms away from the terminal methyl group in their chemical structure, crucial for human health, found in plants (as α-linolenic acid, ALA) and marine sources like algae and fish (as
Location of Fructolysis Why does fructose metabolism or fructolysis occur in liver cells? Properties and Sources of Fructose Absorption of Fructose From Fructose to Fat/Fructolysis/fructose metabolism pathway Steps of fructose metabolism pathway 1. Step 1 2. Step 2 3. Step 3A Metabolic Pathway Notes: At this point, the liver cell can use the same steps
What are Proteins? Definition of Proteins Proteins are large, complex molecules composed of amino acid chains that perform a vast array of functions in living organisms, including catalyzing metabolic reactions, providing structural support, and facilitating cell signaling and transport. Properties of Proteins Synthesis of peptides Peptides are short chains composed of amino acids. These chains,
What are Protein Synthesis Inhibitors? Types of Protein synthesis inhibitors On the basis of target organisms inhibitor of protein synthesis is categories as follows- 1. Acting only on prokaryotes 2. Acting on prokaryotes and Eukaryotes 3. Acting only on Eukaryotes Mechanism of Protein synthesis inhibitors Protein synthesis, a core biological process, occurs at the ribosomal
Proteins, as complex biological molecules, play an essential role in the myriad of processes in living organisms. Consisting of amino acids, proteins can be envisioned as polypeptide structures formed through long chains of these amino acid residues. Therefore, it’s not surprising that they are one of the most abundant organic molecules present in living beings.
What are Lipids? Definition of Lipids Lipids are a group of organic compounds, insoluble in water but soluble in non-polar organic solvents, that serve as energy storage molecules, cell membrane components, and play roles in signaling and insulation. Properties of Lipids Physical Properties of Lipids Chemical Properties of Lipids Physical Properties Chemical Properties Soluble in
What are lipids? Classification of Lipids Based on the Chemical Composition 1. Simple Lipids Simple lipids are fundamental components in the realm of biological molecules. They primarily consist of neutral fats and oils, as well as waxes. These lipids play crucial roles in various biological processes, especially in energy storage and insulation. 2. Compound Lipids
What is Oxidative Phosphorylation? Definition of Oxidative Phosphorylation Oxidative phosphorylation is a metabolic process that occurs in the mitochondria, where energy derived from the electron transport chain is used to produce adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate, with oxygen acting as the final electron acceptor. Sites of oxidative phosphorylation in ETC
The cGMP pathway, short for cyclic guanosine monophosphate pathway, is a crucial signaling mechanism in cells. It involves the synthesis of cGMP from GTP (guanosine triphosphate) through the action of the enzyme guanylate cyclase. cGMP acts as a secondary messenger, similar to cyclic AMP (cAMP), and plays a vital role in various physiological processes. One
What is Photosystem I (PS1)? Definition of Photosystem I (PS1) Photosystem I (PSI) is a crucial protein complex in oxygenic photosynthesis, primarily found in algae, plants, and cyanobacteria. It functions by capturing light energy to drive the transfer of electrons across the thylakoid membrane, from plastocyanin to ferredoxin. This process contributes to the synthesis of
