: They link together through peptide bonds to form long chains called polypeptides, which then fold into complex 3D structures to become functional proteins. Nutritional Classification
: This variable side chain determines the specific chemical properties of each amino acid—such as its size, charge, and solubility—which ultimately dictates how a protein folds and functions. Amino acids : biochemistry and nutrition
From a nutritional standpoint, amino acids are categorized based on the body's ability to synthesize them: : They link together through peptide bonds to
