Every living cell depends on protein for structure, movement, and chemical reactions. Behind every protein lies a chain of amino acid units, joined together in a precise order. Therefore, understanding amino acid chemistry helps explain how proteins fold, function, and interact within the body. This guide explains amino acid structure, classification, and the bonds that…
Lipids are a diverse group of organic compounds that are insoluble in water but soluble in non-polar solvents such as chloroform and ether. Although they are structurally varied, all lipids share this defining hydrophobic character. Lipids serve as the body’s primary energy reserve, and they also form the structural backbone of every cell membrane. Because…
Carbohydrates are everywhere in our daily food, and they are one of the main reasons dentists talk so much about diet. In simple words, carbohydrates are sugars and starches that give the body energy. However, when these sugars stay in the mouth for too long, they feed bacteria that live on teeth, and this leads…
Biochemistry is the science that explains the chemical basis of life. Among its most fundamental topics are Biomolecules and Cell, which form the structural and functional foundation of every living organism. The human body is composed of billions of cells, and each cell contains a variety of biomolecules that work together to maintain life. Therefore,…
