How it is made
Where a peptide comes from, and where the cost of a long chain actually goes.
- How it is madeThirty-nine residues and a fatty acidWhy the metabolic analogues are all roughly the same length, what the diacid on the lysine is doing there, and why they cost what they cost.
- How it is madeWhy a forty-residue peptide costs what it doesSolid-phase synthesis is the same operation repeated once per amino acid. The arithmetic of that repetition is most of the price.
- How it is madeThe two-residue peptidesAt the other end of the shelf from the metabolic analogues sit chains of two, three and four amino acids. Almost everything about them is different.
- How it is madeWhere the word peptide stops meaning anythingA working definition, the boundary with proteins, and the two things in this catalog that are not peptides at all.
