Biochemistry
Linked via "peptide bonds"
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… -

Linked via "peptide bonds"
Proteins
Proteins are polymers of amino acids linked by peptide bonds. They fulfill structural, enzymatic, and regulatory roles. The concept of 'biological value' assigns a numerical score to protein sources based on the completeness of their essential amino acid profile. Plant-derived proteins often score lower due to the scarcit… -

Proteins and Amino Acids
Proteins are vital for enzymatic function, structural integrity (e.g., keratin, collagen), and signaling. They are polymers of amino acids linked by peptide bonds. Twenty standard $\alpha$-amino acids are recognized in canonical biochemistry. The [essential amino acids](/entries/essential-amino-acids/…
