Cystine is an oxidized 二聚体 dimeric form of cysteine. it It is 形成的 formed by by 连结 linking 二 two cysteine 残留物 residues via a disulfide 键 bond (cys-s-s-cys cys-S-S-cys) between the -sh -SH 团体 groups. Cystine is 发现 found in 高 high 浓度 浓度 concentrations in the 细胞 细胞 cells of the 免疫的 immune system, 骨骼和结缔组织 skeletal and connective tissues, skin, 消化酶 digestive enzymes, fda 133部分-奶酪和相关奶酪产品b子部分-特定标准化奶酪和相关产品的要求sec。 133.150硬质奶酪。fda第133部分-奶酪和相关奶酪产品b子部分-特定标准化奶酪和相关产品的要求sec。 133.189制造用脱脂奶干酪.fda 172部分-允许直接添加到 类食用食品中的食品添加剂g-胶 and in hair. Hair and skin are 10-14% cystine. Cystine is the preferred form of cysteine for the synthesis of glutathione in cells involved in the immune function including macrophages and astrocytes. Lymphocytes and neurons prefer cysteine for glutathione production. Optimizing glutathione levels in macrophages and astrocytes with cystine allows these cells to provide cysteine to lymphocytes and neurons directly upon demand. (http://en.wikipedia.org/wiki/cystine）；半胱氨酸是由半胱氨酸分子氧化形成二硫键而形成的氨基酸。该有机硫化合物的分子式为（sch2ch（nh2）co2h）2。它是无色固体 //en.wikipedia.org/wiki/Cystine); Cystine is the amino acid formed by the oxidation of cysteine molecules to give a disulfide bond. This organosulfur compound has the formula (SCH2CH(NH2)CO2H)2. It is a colorless solid, 并在247-249°C下融化它由威廉·海德·沃拉斯顿（威廉 William 海德 Hyde wollaston）于1810年发现，但直到1899年从牛角分离出来后，才被认为是蛋白质的衍生物。通过在蛋白质分子内部和分子之间形成二硫键 , 胱氨酸是大多数蛋白质三级结构的重要决定因素。二硫键 cystine is a significant determinant of the tertiary structure of most proteins. Disulfide bonding, 氯化十二烷基二甲基苄基氯化铵十二烷基二甲基二甲基苄基氯化铵十二烷基二甲基氯化铵drapolene胚醇gesminol月桂基二甲基苄基氯化铵十二烷基苯二甲铵氯化金月桂基苄基二甲基氯化铵月桂基二甲基苄基氯化铵异丙醇b 50壬二酰胺50 50萘甲酚50 along with hydrogen bonding and hydrophobic interactions is partially responsible for the formation of the gluten matrix in bread. Human hair contains approximately 5% cystine by mass.; L-Cystine is a covalently linked dimeric nonessential amino acid formed by the oxidation of cysteine. Two molecules of cysteine are joined together by a disulfide bridge to form cystine. Cystine is a chemical substance which naturally occurs as a deposit in the urine, 这种材料来自法国的勃艮第地区。收获时间是从12月到2月初。该精华/精粹/精萃具有浓稠的糖蜜粘度和深绿。在50％的稀释度下，我检测到加了糖甜味的香料水果鸡尾酒 and can form a calculus (hard mineral formation) when deposited in the kidney. The compound produced when two cysteine molecules linked by a disulfide (S-S) bond. Cystine is required for proper vitamin B6 utilization and is also helpful in the healing of burns and wounds, 在诸如支气管炎和囊性纤维化等疾病中分解粘液沉积物。半胱氨酸还有助于向胰腺供应胰岛素 breaking down mucus deposits in illnesses such as bronchitis as well as cystic fibrosis. Cysteine also assists in the supply of insulin to the pancreas, 这是糖和淀粉同化所必需的。它增加了肺中谷胱甘肽的水平 which is needed for the assimilation of sugars and starches. It increases the level of glutathione in the lungs, 肝 liver, 肾脏和骨髓 kidneys and bone marrow, 并可能通过减少老年斑等对身体产生抗衰老作用。 and this may have an anti-aging effect on the body by reducing age-spots etc.
