关于透明质酸（HA）
Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed Of repeat disaccharide units of glucuronic acid and N-acetylglucosamine.透明质酸（HA）是由葡萄糖醛酸和N-乙酰氨基葡糖的重复二糖单元组成的直链大分子粘多糖。 It widely consists in the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cockscomb, etc.The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid.它广泛地存在于人和动物组织的细胞外空间，玻璃体，脐带，滑膜，滑膜和鸡冠状细胞等中。商业用HA通常是钠盐，称为透明质酸钠，习惯上称为透明质酸。 Hyaluronic Acid is a new biological at home and abroad.透明质酸是国内外的一种新型生物。 Its molecular weight is from several ten thousand to several million.其分子量是从几万到几百万。 It¡¯s aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity.它的水溶液具有出色的保湿能力，高的粘弹性和润滑性。 It is widely used in cosmetics, pharmacy and health and beauty food.它广泛用于化妆品，制药和保健美容食品中。

1.化妆品级透明质酸
Hyaluronic Acid is a natural biotic component, widely existing in skin and any other tissue.透明质酸是一种天然的生物成分，广泛存在于皮肤和任何其他组织中。 It has outstanding moisture keeping ability, thus called Natural Moisturing Factor (NMF) in the world.它具有出色的保湿能力，因此在世界范围内被称为自然保湿因子（NMF）。 It is the best component used in cosmetics for moisture keeping in the nature.它是化妆品中天然保湿的最佳成分。
When Hyaluronic Acid applied to the skin, macromolecular HA can form an air permeable thin layer and keep the skin smooth and moist, and protect the skin from bacteria, dust, and ultraviolet ray.当透明质酸应用于皮肤时，大分子HA可以形成透气的薄层，保持皮肤光滑湿润，并保护皮肤免受细菌，灰尘和紫外线的伤害。 With low molecular HA penetrating into corium, it will slightly enlarge blood capillaries, speed circulation of blood, improve intermediary metabolism and nourishment absorbing ability of skin, thus eliminating wrinkles, increasing skin's elasticity and delaying its aging.低分子HA渗透到真皮中后，会略微增大血管毛细血管，加速血液循环，改善皮肤的中间代谢和营养吸收能力，从而消除皱纹，增加皮肤的弹性并延缓衰老。 Hyaluronic Acid as well can further hyperplasia of epidermis cell, clean oxygen free radical, prevent and rehabilitate breach of skin.透明质酸还可以进一步促进表皮细胞的增生，清除氧自由基，预防和修复皮肤受损。 Its aqueous solution has very high viscosity which can make water become thicker.它的水溶液具有很高的粘度，会使水变稠。 Creams made by means of emulsifying HA with oil is fine and homogeneous with stable emulsifiction.用油乳化HA制成的乳霜细腻均匀，具有稳定的乳化作用。
Hyaluronic Acid is the best natural moisturizing component used in cosmetics.透明质酸是化妆品中使用的最佳天然保湿成分。 It has a good Compatibility具有良好的兼容性
and can be added in various cosmetics such as cream, lotion.可以添加到各种化妆品中，例如乳霜，乳液。 cosmetic water, essence, milk forfacewashing, liquid for bath, agentfor hair washing and protection£¬ mousse, lip stick.化妆水，香精，洗面奶，沐浴液，洗发和护发素慕斯，唇膏。 The incorporated quantities are about 0.05%-0.5%掺入量约为XNUMX％-XNUMX％

2.药用级透明质酸 
HA作为细胞间物质的主要成分，直接关系到细胞内外电解质交换的转移，证明了物理和分子信息的过滤作用。 Macromolecule Hyaluronic Acid can prevent cells from move, hyperplasia, disintegration and engulfment, while low olecule HA has furtherance actions.高分子透明质酸可防止细胞移动，增生，分解和吞噬，而低分子HA具有促进作用。
HA与其他药物的化合物，添加剂可以使药物作用延迟。 With the development of medical technology.随着医疗技术的发展。 HA will be more widely used in medicine医管局将在医学上更广泛地使用
3.食品级透明质酸
Hyaluronic Acid content is about 15g in a human body.人体中的透明质酸含量约为XNUMX克。 It plays an important role in human biologic activity.它在人类生物学活动中起着重要作用。 With the decrease of HA content in skin, the water retaining ability of the skin is weakened, the skin looks coarse and wrinkle.随着皮肤中HA含量的降低，皮肤的保水能力减弱，皮肤看起来粗糙和皱纹。 The decrease of HA in other apparatus will lead to arthritis, arteriosclerosis, plus disorder and brain atrophy.其他设备中HA的减少将导致关节炎，动脉硬化，疾病和脑萎缩。 All in all the decrease of HA in human body will lead to premature senility.总而言之，人体中HA的减少将导致早衰。 
Oral Hyaluronic Acid can increase HA content in human body, supply deficiency of HA.口服透明质酸可增加人体中的HA含量，供应不足。 By digesting and absorbing HA, skin can be made moist, smooth, soft and rich spring.通过消化和吸收HA，可以使皮肤滋润，光滑，柔软和丰富。 Oral HA can defer crowd senility;口服HA可以延缓人群的衰老； prevent arthritis, arteriosclerosis, plus disorder and brain atrophy.预防关节炎，动脉硬化，疾病和脑萎缩。 Oral HA can make one full of beans and be rich in youth energy.口服HA可以使一个豆子饱满，并富含青春活力。
