上記の要因全てに関連!
融点が高いということは相互結合作用が強いということ
→柔軟性が低い

赤血球の直径は7μm、厚さ2μm
直径1μmの毛細血管も通常なら変形して通過できるが、
飽和脂肪酸が多いと、細胞膜の柔軟性が低下し、硬くなる

脂質

上記の要因全てに関連!
細胞膜の脂質は、細胞の構造を保つためだけでなく
各種生理活性物質の材料の貯蔵庫でもある!
トロンボキサンA2とトロンボキサンA3
トロンボキサンA2は血小板凝集作用が強い!
トロンボキサンA3は弱い!
→抗血小板薬はトロンボキサンA3の合成や作用を阻害する

→血液をサラサラにする
→動脈硬化を予防
血管収縮と血管拡張のバランスは
トロンボキサンA2とPGI2で成り立っている!

DHAやEPAをたくさん取ると
TXA3の割合が増え、血管緊張性が低下

エスキモーの人々は血液が固まりにくく、
高血圧や心血管疾患、脳血管系疾患の
割合が有意に低いことが統計的に
わかっています。
※グリーンランドに住む。イヌイットとも。
血中EPA、DHA濃度が高い。
動脈硬化のメカニズム
EPAが主成分。鰯や鯖に含まれる不飽和脂肪酸と同じ成分
作用1

血小板の作用を抑える。血行障害による手足のしびれに

作用2

血中の中性脂肪を減らし、動脈硬化のリスクを減らす
まとめ
魚には融点の低い不飽和脂肪酸が豊富に含まれる

→弾力のある細胞膜に(中性脂肪も少ない)
魚に多く含まれるω−3脂肪酸(EPA、DHA)は赤血球凝集作用
血管収縮作用の弱い、トロンボキサンA3の材料となる。

→血液がサラサラに
→血管緊張性が低下

→

毛細血管の閉塞
動脈硬化防ぐ
松阪牛の特徴と脂肪融点

松阪牛の美味しい訳は…。脂肪融点
まろやかな口当たりは脂肪が溶ける温度で決まり
○松阪牛の脂肪は低い温度で溶ける
不飽和脂肪酸は融点が低いので、これを多く含む牛肉
を口に入れるとすぐに溶けてまろやかな感じになりま
す。
(松阪牛の特徴)
松阪牛は不飽和脂肪酸の比率が高いので、乳用種や交雑
種はもちろん、同じ和牛と比べてもさらに融点が低く、
非常に舌ざわりが良くなって美味しさが強調されます。
※ 松阪牛の脂肪融点は、現在の研究では17度前後。中
には13~14度くらいのものもあり、手のひらに乗せ
ただけで溶け出すほどです。
○牛の品種と脂肪融点
品 種組
織 融点(℃)
松阪牛 皮下脂肪 17.4
和 牛 皮下脂肪 25.9
交雑種 皮下脂肪 29.9
乳用種 皮下脂肪 30.2
