History[edit source | edit]
The letter M is derived from the Phoenician Mem, via the Greek Mu (Μ, μ). Semitic Mem probably originally pictured water. It is known[dubious – discuss] that Semitic people working in Egypt c. 2000 BC borrowed a hieroglyph for "water" that was first used for an alveolar nasal (/n/), because of the Egyptian word for water, n-t. This same symbol became used for /m/ in Semitic, because the word for water began with that sound.

The letter 'm' represents the bilabial consonant sound, [m], in Classical languages as well as the modern languages. The Oxford English Dictionary (first edition) says that 'm' is sometimes a vowel in words like spasm and in the suffix -ism. In modern terminology, this would be described as a syllabic consonant — IPA [m̩].

定義
- L-アミノ酸、D-アミノ酸がある。一般的に生合成されるポリペプチドはL-アミノ酸を材料としている。D-アミノ酸は細菌が産生し、ごく短いペプチドとして特に、細胞壁に存在する。これはペプチダーゼによる分解を免れるためと言われている。D-アミノ酸を含むポリペプチドは、通常の翻訳経路で生合成されない。(FB.58)
