TG是甘油三酯（Triglyceride）的英文缩写，是长链脂肪酸和甘油形成的脂肪分子。
甘油三酯（TG）是一种有机化合物，由甘油的3个羟基与3个脂肪酸分子酯化生成的甘油酯。为非极性物质，以非水合形式贮存于体内，是体内储量最大和产能最多的能源物质。植物性三酰甘油多为油，动物性三酰甘油多为脂。固、液态的三酰甘油统称为油脂。
甘油三酯是人体内含量最多的脂类，大部分组织均可以利用甘油三酯分解产物供给能量，同时肝脏、脂肪等组织还可以进行甘油三酯的合成，在脂肪组织中贮存。
临床意义：
1.增高：甘油三酯为心血管疾病的危险因素。血清甘油三酯水平受年龄、性别和饮食的影响。血清甘油三酯增高可见于家族性高甘油三酯血症，饮食大量甘油三酯和继发于某些疾病如糖尿病、甲状腺功能减退、肾病综合征和胰腺炎、动脉粥样硬化、糖原贮积病等。
2.降低：见于甲状腺功能亢进症、肾上腺皮质功能降低、肝功能严重低下、慢性阻塞性肺疾患、脑梗塞、营养不良、先天性α-β脂蛋白血症等。

TG＜0.56mmol/L。
遗传性疾病，如低β－脂蛋白血症、无β－脂蛋白血症等。
其他，如肝脏疾病、吸收不良综合征；甲状腺功能亢进、慢性肾上腺皮质功能不全；肝素等药物影响。
血清TG水平受生活方式、年龄、性别等因素影响较大，标本采集前应注意清淡饮食。TG水平与胰岛素抵抗有关，是糖尿病的独立危险因子。检验结果的临床意义必须由临床专业医师结合病史、症状、体征及其他辅助检查结果，全面综合分析判断。

saccharide polymers linked by β-1,4 glycosidic bonds参见 http://www.science24.com/paper/15607Recently, a carbon-based solid acid consisting of polycyclic aromatic carbon combined functional groups such as a sulfonic acid groups has been demonstrated to act as a strong solid acid catalyst for the hydrolysis of cellulose into oligosaccharide and glucose in the presence of the water. However, the details of the amorphous carbon structure and catalysis-related structure remain to be clarified. Thus, the hydrolysis of water-soluble β-1,4 glucan, -------saccharide polymers linked by β-1,4 glycosidic bonds-------, was examined on the carbon material to understand the relationship between the catalytic activity and the structure in the present study. Carbon-based solid acid catalysts were prepared by sulfonation of amorphous carbon obtained by carbonization of cellulose, and their catalytic activities were evaluated through the hydrolysis of water-soluble β-1,4 glucan such as cellobiose and cellohexaose. The carbon material catalytically hydrolyzed cellobiose into glucose without the production of the by-products such as 5-hydroxymethylfurfural, and levulinic acid, exhibiting three times higher activity for the hydrolysis of cellobiose than the conventional solid acid catalysts. Furthermore, there was no noticeable difference in the catalytic activity and the structure before and after reaction. In the case of the hydrolysis of cellohexaose, although the tested conventional solid acid catalysts could hardly hydrolyze cellohexaose, the carbon catalyst exhibited much higher catalytic performance than the conventional solid acid catalysts. The adsorption of β-1,4 glucan on each of the solid acid catalysts suggests that the high catalytic performance of the carbon catalyst is attributed to the ability of the material to adsorb β-1,4 glucan, which does not adsorb to other solid acids.

来源
血浆中的甘油三酯的来源主要有两种：
①外源性：由食物中摄取的脂肪于肠道内，在胆汁酸、脂酶的作用下被肠黏膜吸收，在肠黏膜上皮细胞内合成甘油三酯。
②内源性：体内自身合成的甘油三酯主要在肝脏，其次为脂肪组织。甘油三酯的主要功能是供给与储存能源，还可固定和保护内脏。血清甘油三酯测定是血脂分析的常规项目。
