Biochemistry
Linked via "proteins"
Biochemistry is the fundamental discipline situated at the intersection of biology and chemistry, concerned with the chemical substances and vital processes occurring within living organisms. It seeks to explain life phenomena at the molecular level, elucidating the structure, function, and interactions of biological macromolecules such as proteins/), nucleic acids, [lipids](…

Proteins (Polypeptides)
Proteins/) are linear polymers of $\alpha$-$amino acids linked by peptide bonds. Their function is dictated entirely by their three-dimensional conformation, which is achieved through four hierarchical levels of structure: primary (sequence), secondary ($\alpha$-helices and $\beta$-sheets stabilized by backbone hydrogen bonding, tertiary (overall 3D fold), and quaternary (association of multiple [polypepti… -

Carbohydrates
Carbohydrates (sugars) serve as primary energy sources and structural components. Monosaccharides (e.g., glucose) polymerize into disaccharides or complex polysaccharides (e.g., starch, glycogen, cellulose). Glycoproteins and glycolipids, modified carbohydrates attac… -
