以下是我看法
請比我專業的大大鞭小力一點 謝謝~
膠原蛋白就像無效派所說,分子超大穿不過皮膚只能留在表皮保濕、吃進去會消化掉,跟
肉一樣沒什麼特別的,但是但是~~!!!!!
重點來惹~
不知大家有沒有注意自己買來吃的膠原相關產品都有特別標示
“低分子(明X)”
“胜肽(蜜XXX)”
“奈米化”…
換句話說就是把膠原蛋白切得很細很小,其實這樣不能稱為蛋白,
我們姑且稱膠原胜肽
我在某研討會問過膠原胜肽的研發人員,膠原胜肽約是3~5個胺基酸大小,
這size真的可稱為小分子了,很多藥物都長得比它大。
而膠原蛋白大概是由3000個胺基酸構成的
學藥學的人都知道,易穿透細胞膜的物質必需是極性小(脂溶性)、小分子、不帶電,而
膠原胜肽剛剛好都符合
登登登~
這就是為啥很多人吃外面所謂膠原蛋白粉很有效了
因為吃的不是無效派所謂的大分子的膠原蛋白
而是好吸收的小分子膠原胜肽~
再稍微解釋一下物質進入腸胃道的消化吸收好了~
細胞只有小分子(葡萄糖、胺基酸、脂肪酸等)可進入,
也就是只能吸收小分子
蛋白質是大分子,要透過胃腸道的消化酵素分解成
胺基酸才能進入細胞
這個過程稱為消化
而吃進消化道的膠原胜肽,不用像蛋白質一定要經過分解才能進入細胞,
所以可以保持完整形態被吸收
當然平常要像j大所說補充維他命C促身體合成膠原蛋白,
因為人類需要的膠原蛋白量非常非常大,他是動物細胞外的胞外基質主成分之一,我們可
以說幾乎每個細胞都是被膠原蛋白圍起來的,
人類的肌腱、骨頭、軟骨、血管、內臟、肌肉等等也都需要膠原蛋白
說真的人體膠原蛋白用量這麼多
我個人是認為可以補充啦
而且每個地方都在搶合成膠原蛋白
我們的皮膚憑什麼搶贏更多原料
所以我自己是有在吃啦XD
有版友問吃了膠原怎麼跑臉上
吃下去我認為是隨血液循環全身性吸收,每個器官都分到更多膠原蛋白,所以頭髮指甲皮
膚都會有影響
如果是抹臉上就是臉留住比例較多,
但是吃的效果會比抹的好,就像藥物吃的比抹的有效,因為吃的話身體裡的濃度會更高,
加上皮膚蠻厚(膠原胜肽要很辛苦的通過好幾層細胞)的抹臉上吸收多少很難說
總而言之,目前市售的膠原蛋白都是好吸收的小分子膠原蛋白,基本上是有效的啦!
好啦 報告完畢~感謝收看
