Lipids are a broad and diverse group of hydrophobic (water-insoluble) organic compounds composed mainly of carbon (C), hydrogen (H), and oxygen (O). Some lipid may also contain nitrogen (N) and phosphorus (P). They play essential roles in energy storage, membrane structure, signaling, and protection in living organisms. Classification of Lipids Lipids are categorized based on … Read more
Carbohydrate are vital organic molecules composed of carbon, hydrogen, and oxygen atoms, typically in a ratio of 1:2:1. These molecules play a pivotal role as an essential nutrient and primary energy source for most living organisms, besides serving structural functions in some instances. Classification of Carbohydrate Carbohydrate are categorized based on their complexity into: Monosaccharides … Read more
Thermodynamic Treatment of Stability constants quantify the strength of the complex formed between a central atom and ligands.
