The structure (abbreviated) of the polysaccharide cellulose, a major structural component of plant cell walls, wood. It is just an unbranched polymer of beta-glucose. Only a small fragment of the potentially infinite polymer is shown. Drawn in Inkscape. セルロース 多糖類 砂糖 セルロース
The structure a triacyglicerol, a.k.a fat. This fat molecule possesses three identical, saturated fatty acid (palmitic acid) units, linked to a glycerol molecule. Drawn in Inkscape. 脂肪 トリグリセリド トリアシルグリセ ロール 脂肪分子
The abbreviated structure of the storage polysaccharide starch; just a short segment shown (starch is a long, potentially infinite, polymer of alpha-glucose molecules). Unbranched starch, like the one drawn here, is called amylose. Drawn in Inkscape. 澱粉 多糖類 砂糖 澱粉
The structure (abbreviated) of the structural polysaccharide chitin, a major component of the exoskeleton of arthropods (spiders, crustaceans, insects, etc.) and of the cell wall of fungi. It is similar to cellulose, but with a different side group on the carbon 2 of glucose. Absorbable surgical thread can be made of this material. Only a small fragment of the potentially infinite polymer is shown. Drawn in Inkscape. キチン 多糖類 砂糖 キチン
The structure (abbreviated) of the hexose sugar alpha-glucose. Drawn in Inkscape. グルコース 分子 ヘキソース グルコース
The simplified "cloverleaf" tRNA structure (from genome sequence of the bacterium Gardnerella vaginalis, as predicted by tRNAscan) for the glycine amino acid (GCC anticodon). Drawn in Inkscape. 転送 科学 生物学 転送の RNA
A simple balls-and-sticks model of a caffeine molecule. Oxygen is red, carbon is blue-grey, nitrogen gree; hydrogens not shown. Drawn in Inkscape. 分子 モデル カフェイン カフェイン分子
The structure (abbreviated) of the disaccharide sucrose, a.k.a. common sugar (the one used in the kitchen). It is the polymer of an alpha-glucose and a fructose units. Drawn in Inkscape. スクロース 砂糖 二糖類 ショ糖 （砂糖）
The simplified "cloverleaf" tRNA structure (from genome sequence of the bacterium Gardnerella vaginalis, as predicted by tRNAscan) for the glycine amino acid (GCC anticodon). Different parts of the structure highlighted and tagged. Drawn in Inkscape. 転送 科学 生物学 トランスファー RNA 2
