寡肽-4Oligopeptide-4在化妆品中有什么应用什么是寡肽？An oligopeptide, often just called peptide (oligo-, "a few"), consists of two to twenty amino acids and can include dipeptides, tripeptides, tetrapeptides, and pentapeptides. Some of the major classes of naturally occurring oligopeptides include aeruginosins, cyanopeptolins, microcystins, microviridins, microginins, anabaenopeptins, and cyclamides. Microcystins are best studied, because of their potential toxicity impact in drinking water.[1] A review of some oligopeptides found that the largest class are the cyanopeptolins (40.1%), followed by microcystins (13.4%).多肽的一种分类，分子量段一般在1000道尔顿以下，也称作小肽，寡肽、低聚肽或称为小分子活性肽，一般由4--10个氨基酸组成，超过的就称为多肽，氨基酸为50多个以上的多肽称为蛋白质。与其他肽的区别是，在人体不需消化，即可直接吸收。
寡肽又可分为：寡肽-1、寡肽-3、寡肽-5等，寡肽-6又称为六肽或六胜肽。什么是寡肽-4？Oligopeptide-4 is a synthetic 91 amino acid peptide consisting of alanine, arginine, aspartic acid, glutamic acid, glycine, histidine, hydroxyproline, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tyrosine and valine。寡肽-4 是一种由 93 个氨基酸组成的蛋白质，由丙氨酸，精氨酸，天冬氨酸，谷氨酸，甘氨酸，组氨酸，羟脯氨酸，异亮氨酸，亮氨酸，赖氨酸，蛋氨酸，苯丙氨酸，脯氨酸，丝氨酸，苏氨酸，酪氨酸和缬氨酸组成。寡肽-4 通过与皮肤细胞受体结合，强化生长因子信号传递，促进表皮细胞增殖分化，增加角质细胞、纤维母细胞、玻尿酸及弹力蛋白合成等，达到皮肤更新以及抗老化、长发的效果。寡肽-4的作用机理是什么？寡肽-4 通过产生新的皮肤细胞，淡化和预防皱纹生成。寡肽-4 增加弹力蛋白和胶原蛋白合成，淡化红斑。寡肽-4 使肌肤纹理更加细腻，并有一定的燃脂功效。寡肽-4 促进毛囊产生健壮的毛干，强化头发。
