Questions about the Amino Acids poster

What’s on the Amino Acids poster?

A definition and 6 facts worth remembering. An amino acid has a central carbon bonded to an amine group, a carboxyl group, a hydrogen and a variable R group. The R group determines the amino acid's chemistry. Twenty amino acids are used in protein synthesis.; Nine are essential in humans — they must come from the diet.; R groups may be polar, non-polar, acidic or basic.; Non-polar R groups cluster inside the folded protein.; Cysteine's R group forms disulfide bridges.; Peptide bonds form between the amine of one and the carboxyl of the next.; Standard — 20; Essential — 9; Bond — peptide; Sickle cell disease is one glutamic acid replaced by valine — polar swapped for non-p…. That single substitution changes the surface chemistry enough to make haemoglobin polymerise, deforming the whole cell.

Who is the Amino Acids poster for?

Amino Acids belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning biochemistry can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Amino Acids poster?

Twenty amino acids, one general structure, twenty different R groups. A wall chart earns its place by being glanceable from where the work is happening, so Amino Acids belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.

What other posters go with Amino Acids?

Protein Structure, ATP and Food Tests sit alongside Amino Acids in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Protein StructureATPFood Tests

Is the Amino Acids poster free to download and print?

Yes. Amino Acids downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Amino Acids poster print at?

Amino Acids is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Amino Acids loses nothing.Printing guide
