上禮拜日
跟我家老媽在桃園火車站前要走路新光時
一位很像直銷的推銷員 把我們攔下
認認真真的看著我媽的臉.... 然後補一句
"小姐 妳的臉部嚴重缺乏膠原蛋白喔"....
我心裡OS有夠沒禮貌!
那位推銷員就如同預期開始推銷她家的膠原蛋白粉
一開口沒多久 我馬上擋在我媽面前
他嘮叨的說 膠原蛋白粉可以補充臉部皮膚的彈性蛋白
會讓皮膚較豐潤有彈性 年紀大了就一定要補充
不然皮膚會快速的"崩垮"! =..=
我回問她: 這粉吃進肚裡可以不用被分解成小分子直接跑到臉部皮膚?
膠原蛋白吃進肚裡 不會被分解成胺基酸??
分解成胺基酸後 這粉可以指定促進合成膠原蛋白?
就算可以合成膠原蛋白 人體皮膚是最大的器官
你是怎麼可以確定會先補充臉部肌膚?
最後我又補一句 我生理 生化 藥學可沒有白念..........
推銷員 臉瞬間變超臭 爽啦!
我大概解釋一下膠原蛋白
collagen是一種結締組織蛋白, 由三條多胜肽組成,每條有一千多個胺基酸,
看到這裡 有點化學概念可以了解 這分子量是很大的
所以如果用外敷 確定進的去皮膚嗎??
再來講是由哪幾種胺基酸組成 大致上是以gly pro hyp leu等等
gly是最主要的 每三組就一定會出現一次,
自然界目前共22種胺基酸 而膠原蛋白的胺基酸 基本上一顆雞蛋裡面都有....
要補充膠原蛋白的胺基酸
不如補充可以穩定膠原蛋白化性結構的化合物 或是促進增生
像是vit.C 在膠原蛋白合成過程中,
可以幫助enzyme氫氧化作用,讓膠原蛋白的合成過程更加穩定
如果c不足,就有可能會造成膠原蛋白合成出問題,
壞血病部分成因也是這樣造成,
所以如果要我吃膠原蛋白撫平肌膚, 我寧願吃vit C!
