  2. Peptide synthesis - Wikipedia

    en.wikipedia.org/wiki/Peptide_synthesis

    A new development for producing longer peptide chains is chemical ligation: unprotected peptide chains react chemoselectively in aqueous solution. A first kinetically controlled product rearranges to form the amide bond. The most common form of native chemical ligation uses a peptide thioester that reacts with a terminal cysteine residue. [58]

  3. Peptide bond - Wikipedia

    en.wikipedia.org/wiki/Peptide_bond

    Peptide bond formation via dehydration reaction. When two amino acids form a dipeptide through a peptide bond, [1] it is a type of condensation reaction. [2] In this kind of condensation, two amino acids approach each other, with the non-side chain (C1) carboxylic acid moiety of one coming near the non-side chain (N2) amino moiety of the other.

  4. Fermentation - Wikipedia

    en.wikipedia.org/wiki/Fermentation

    Fermentation is used to produce the heme protein found in the Impossible Burger. Fermentation can be used to make alternative protein sources. It is commonly used to modify existing protein foods, including plant-based ones such as soy, into more flavorful forms such as tempeh and fermented tofu.

  5. Protein - Wikipedia

    en.wikipedia.org/wiki/Protein

    Chemical structure of the peptide bond (bottom) and the three-dimensional structure of a peptide bond between an alanine and an adjacent amino acid (top/inset). The bond itself is made of the CHON elements. Resonance structures of the peptide bond that links individual amino acids to form a protein polymer

    en.wikipedia.org/wiki/Ribosomally_synthesized...

    The B protein is an adenosine triphosphate-dependent cysteine protease that cleaves the leader region from the precursor peptide. The C protein displays homology to asparagine synthetase and is thought to activate the carboxylic acid side chain of a glutamate or aspartate residue via adenylylation.

    A neuropeptide is a peptide that is active in association with neural tissue. A lipopeptide is a peptide that has a lipid connected to it, and pepducins are lipopeptides that interact with GPCRs. A peptide hormone is a peptide that acts as a hormone. A proteose is a mixture of peptides produced by the hydrolysis of proteins. The term is ...

  8. Protein metabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_metabolism

    Essential amino acids must be consumed and are made in other organisms. The amino acids are joined by peptide bonds making a polypeptide chain. This polypeptide chain then goes through post translational modifications and is sometimes joined with other polypeptide chains to form a fully functional protein.

  9. Biosynthesis - Wikipedia

    en.wikipedia.org/wiki/Biosynthesis

    A protein is a polymer that is composed from amino acids that are linked by peptide bonds. There are more than 300 amino acids found in nature of which only twenty two, known as the proteinogenic amino acids, are the building blocks for protein. [24]
