In this study, we examined the effects of various molecular weights (1, 10, 50, 100, 660, and 1500 kDa) of sodium hyaluronate (HA), which were prepared by enzyme hydrolysis, on the collagen synthesis, anti-inflammation and skin absorption. These HA did not significantly affect the viability of human...

히알루론산나트륨은 무엇으로 구성되었는가? | 히알루론산나트륨(sodium hyaluronate, HA)은 Nacetyl glucosamine (NAG)과 glucuronic acid로 구성되어 있으며 β-1,3-결합 및 β-1,4-결합으로 된 산성, 뮤코 다당류로 고점도성, 보습성, 생체적합성 등의 특징을 지닌다[1]. 콜라겐 및 엘라스틴과 함께 피부 3대 요소 중 하나인 HA은 피부 내 진피의 주요성분으로 수분보유 능력이 뛰어나 수분유지, 세포 간 간격유지뿐만 아니라 세포의 성장, 분열, 이동 등에 관여하는 것으로 알려져 있다[2,3]. | |
히알루론산나트륨은 어떻게 합성되는가? | 콜라겐 및 엘라스틴과 함께 피부 3대 요소 중 하나인 HA은 피부 내 진피의 주요성분으로 수분보유 능력이 뛰어나 수분유지, 세포 간 간격유지뿐만 아니라 세포의 성장, 분열, 이동 등에 관여하는 것으로 알려져 있다[2,3]. HA은 주로 각질형성세포와 섬유아세포에서 히알루론산나의 합성효소(hyaluronic acid synthase, HAS)에 의해 합성되고, 합성되는 동안 세포외기질에 축적되는 것으로 알려져 있는데, 노화가 진행되면서 자연스럽게 히알루론산의 양도 감소하여, 피부 내 히알루론산의 감소는 피부의 수분부족, 주름발생 및 탄력감소의 원인 중 하나이다[4,5]. | |
히알루론산의 분자량이 커지면 발생하는 특징은 무엇인가? | 1 × 106 ∼ 10 × 106 dalton (Da)으로 매우 다양한데, 분자량에 따라 점성, 보습성 및 탄성이 좌우된다[6,7]. 히알루론산은 분자량이 커지면 점성과 탄성이 커지는 특징이 있지만, 피부에 적용할 시 진피층을 통과하지 못하는 문제점이 있다[8,9]. 따라서 독성이 없고 피부 투과도가 높은 저분자 히알루론산을 제조하여 세포 외 기질에 히알루론산을 보충함으로써, 피부의 수분 보충 및 탄력저하를 막으려는 노력이 계속되고 있다[8,10]. |
