Bachem amino acids are protected building blocks used in peptide synthesis, and the Bachem periodic chart of amino acids is a standard lab reference.
Bachem amino acids are the protected amino acid derivatives — mainly Fmoc-, Boc-, and Z-protected building blocks — that Bachem AG manufactures and sells for peptide synthesis. The phrase also refers to the Bachem periodic chart of amino acids, a reference poster that lists the 22 proteinogenic amino acids with their structures, one-letter codes, and side-chain properties. Bachem is a Swiss peptide and amino acid producer founded in 1971 and headquartered in Bubendorf, Switzerland.
What Bachem Amino Acids Are
Bachem is not a supplement brand. It is a catalog supplier and contract manufacturer that sells amino acid derivatives, resins, and custom peptides to pharmaceutical companies, contract research organizations, and academic laboratories.
Its amino acid catalog typically covers:
- Nα-protected amino acids such as Fmoc- and Boc-derivatives used in stepwise chain assembly.
- Side-chain protected amino acids carrying groups like tBu, Trt, Pmc, or Pbf to block unwanted reactions.
- Unusual and non-natural amino acids used to build modified or stabilized peptide sequences.
- Preloaded resins that let a synthesizer start chain growth from the C-terminus.
- Stable isotope-labeled amino acids for mass spectrometry and metabolic tracing work.
Most of these materials are sold as research-grade reagents. Bachem also produces a smaller set of amino acid and peptide active pharmaceutical ingredients under GMP for companies that hold the relevant regulatory filings.
Inside the Bachem Periodic Chart of Amino Acids
The periodic chart of amino acids is a wall chart Bachem has distributed for decades. It arranges the amino acids in a grid that mirrors the periodic table, grouping residues by side-chain chemistry rather than atomic number.
What the chart shows
- Full chemical structures for each amino acid
- Three-letter and one-letter abbreviations
- Molecular weight and molecular formula
- Side-chain pKa values and charge at physiological pH
- Hydrophobicity, polarity, and residue class
- Codons that specify each residue
Chemistry departments, peptide labs, and classrooms often pin the chart near a synthesis station because it puts the data a researcher needs in one place. The bachem periodic chart of amino acids is a study aid and quick-reference sheet, not a product list, and nothing on it is intended as medical guidance.
A common mistake is treating the chart as an ordering guide. Each entry describes a free amino acid, while the compounds a lab actually buys are derivatives with protecting groups attached — and those appear in the product catalog instead.
Protected Amino Acids and Why They Matter
Solid-phase peptide synthesis adds one residue at a time. Every coupling step requires that the alpha-amine and any reactive side chain be temporarily blocked, or the growing chain will branch and the final product will be a mixture.
| Derivative family | Protecting group | Cleavage condition | Typical use |
|---|---|---|---|
| Fmoc-amino acids | Fmoc on Nα | Piperidine (base) | Standard SPPS |
| Boc-amino acids | Boc on Nα | Trifluoroacetic acid | Boc SPPS, HF cleavage |
| Z-amino acids | Cbz on Nα | Hydrogenolysis | Solution-phase synthesis |
| Side-chain protected | tBu, Trt, Pbf, Pmc | Varies by group | Prevents side reactions |
| Preloaded resins | Fmoc-AA on resin | Final TFA cleavage | Chain start at C-terminus |
Fmoc chemistry dominates modern synthesis because deprotection is mild and orthogonal to acid-labile side-chain groups. Boc chemistry still appears in older processes and in routes that require strong acid cleavage.
Bachem amino acids in this context are reagents, not finished drugs. Their purity — usually reported by HPLC as a percentage of the target peak — directly affects coupling efficiency and the yield of the final peptide.
Quality Control and Documentation
Peptide manufacturers buy amino acid derivatives in quantities ranging from grams to multi-ton lots. A single impurity can propagate through dozens of coupling steps, so documentation matters as much as the certificate of analysis.
- HPLC purity traces and mass spectrometry confirmation
- Chiral purity testing to confirm the correct isomer where required
- Water content measured by Karl Fischer titration
- Batch-specific certificates of analysis and stability data
- ISO 9001 quality systems and, for API work, GMP-compliant manufacturing
For reproducible results, purchase from a supplier that offers lot traceability and a documented change-control process. Bargain amino acids with thin documentation often cost more in failed syntheses.
How Bachem Materials Fit Into Broader Peptide Research
Amino acids are only one input in a research pipeline. Laboratories that study metabolic peptides frequently weigh aod 9604 vs mots-c when selecting a comparator, and both compounds ultimately depend on the same supply chain of protected building blocks.
Handling questions overlap as well. Searches for how to take thymosin alpha 1 and for supplies such as bacteriostatic water walgreens reflect how often bench work involves reconstitution, cold storage, and careful record keeping.
Safety discussions deserve the same attention. Reports of ss 31 side effects and similar concerns underline a simple point: research chemicals are not consumer products, and decisions about human use belong with a licensed healthcare professional.
Safety, Regulatory, and Practical Notes
Bachem amino acids are laboratory and industrial reagents. They are not dietary supplements, and they are not approved by the FDA for human consumption.
Researchers should handle them with standard personal protective equipment, work in a ventilated area or fume hood, and follow the safety data sheet for each compound. Store derivatives as labeled, generally desiccated and below room temperature.
Anyone considering a peptide for personal use should speak with a physician or pharmacist first. Self-directed use of research-grade material carries risks that laboratory purity specifications were never designed to address.
Bachem amino acids remain a standard reference point in peptide chemistry because they pair a well-documented product catalog with the periodic chart of amino acids that generations of chemists have used as a fast visual index.
Frequently Asked Questions
What is the Bachem periodic chart of amino acids?
It is a wall chart that arranges the amino acids in a grid resembling the periodic table, showing structures, one-letter and three-letter codes, molecular weights, side-chain properties, and codons. Bachem distributes it as a reference for labs, classrooms, and chemistry departments. It is a study aid, not a product catalog or dosing guide.
Are Bachem amino acids the same as amino acid supplements?
No. Bachem sells protected amino acid derivatives, such as Fmoc- and Boc-amino acids, that serve as reagents in peptide synthesis. Dietary supplements are formulated for oral consumption and regulated as foods or nutraceuticals. The two categories share a name but differ in purity specifications, packaging, and intended use.
Can Bachem amino acids be used in humans?
Bachem's catalog amino acids are sold for research and manufacturing use, not for human consumption, and they are not FDA-approved as drugs. A limited number of peptide active pharmaceutical ingredients made under GMP are used in approved medicines, but those go through formal regulatory review. Anyone considering a peptide for personal use should consult a licensed healthcare professional.
