lysine
リジン
解説 Definition
lysine は、タンパク質を作るのに必要なアミノ酸の一種で、リジンという意味です。日本語の「リジン」とほぼ同じ専門用語で、栄養学や生化学の文脈でよく使われます。
An essential amino acid used by the body to make proteins and obtained through the diet because humans cannot produce enough of it. It occurs in many protein-rich foods and may also be included in nutritional supplements.
覚え方のコツ Memory Tip
lysine は日本語でも使う「リジン」で、体内で十分に作れず食事から取る必要がある必須アミノ酸です。lysine-rich foods、lysine supplement、amount of lysine の組み合わせで覚えましょう。語尾 -ine は化学物質名に多く、同じアミノ酸名の glycine と綴りが似ますが、lysine は先頭が ly- です。
Remember lysine as an essential amino acid: “essential” means the body must obtain it from food rather than make enough on its own. Link it with practical phrases such as lysine-rich foods, a lysine supplement, and the amount of lysine in a grain sample. The ending -ine appears in many chemical and biochemical names. Be careful not to confuse lysine with glycine, another amino acid with a similar ending. Focus on the initial spelling ly- and picture lysine listed among the amino acids on a nutrition or supplement label.

lysine の語源・成り立ち Etymology
ギリシャ語 lysis（分解・溶解）に由来し、化学接尾辞 -ine を付加。タンパク質の加水分解で初めて発見されたアミノ酸のため「分解」に因んで命名された。関連語：analysis（分析）、dialysis（透析）。分解から見つかった必須アミノ酸。
The name lysine was created in scientific terminology from Greek lysis, meaning “loosening, dissolution, or decomposition,” together with the chemical naming suffix -ine. It was chosen in connection with the substance’s isolation from products obtained through the hydrolysis, or chemical breakdown, of protein. Related scientific words built from the Greek root include analysis and dialysis. In modern English, lysine is the standard biochemical name for this particular essential amino acid.
