覚え方のコツ Memory Tip
glycine はタンパク質を構成するアミノ酸「グリシン」です。ギリシャ語の「甘い」に由来する glyc- を、glucose や glycerin に見られる甘味関連の形と結びつけます。the simplest amino acid、glycine supplement の組み合わせで、糖そのものではなくアミノ酸だと区別して覚えましょう。
Connect the glyc- part of glycine with Greek vocabulary associated with sweetness, also reflected in scientific words such as glucose and glycerin. Glycine received its name because of its sweet taste, but remember that it is an amino acid, not a sugar. Its structure is especially simple because its side chain is only a hydrogen atom. Useful phrases include the simplest amino acid, glycine in a sample, and a supplement containing glycine. These combinations anchor the word in chemistry and nutrition rather than in everyday descriptions of sweet food.

glycine の語源・成り立ち Etymology
近代科学ラテン語 glycine で、ギリシャ語 glykys「甘い」＋化学語尾 -ine から成ります。発見時に甘味をもつことが名の由来で、「甘いもの」という感覚がそのまま語名に残っています。glycol, glycerin が関連語です。
The scientific name glycine was created from Greek glykys, meaning “sweet,” with the chemical suffix -ine. The substance was given a sweetness-based name because it has a sweet taste. It was first isolated in the nineteenth century from gelatin and was initially known by another name connected with gelatin. Glycine later became the standard term. The element glyc- also appears in several scientific terms historically associated with sweetness or sugar-related substances.
