Lipids 30 | 脂质 31 | are defined as substances from living organisms that 32 | 被定义为物质生命体 33 | dissolve in nonpolar solvents such as ether (乙醚), 34 | 溶于非极性溶剂,如醚(乙醚), 35 | chloroform (氯仿), and acetone but not appreciably 36 | 丙酮氯仿(氯仿),但不明显 37 | in water. 38 | 在水里。 39 | • Lipids are ester compounds composed of fatty acids 40 | •脂质脂肪酸组成的是酯化合物 41 | and alcohols. 42 | 和醇。 43 | Main contents 44 | 主要内容 45 | • Biological roles that lipid has 46 | •生物角色,脂质 47 | • Structure and properties of fatty acids(脂肪酸) 48 | • Structure and the properties of fatty acids (fatty acid) 49 | • Classification of lipid 50 | •脂类的分类 51 | • Structure of triglyceride/fat(甘油三酯/脂肪) 52 | • Structure of triglyceride/fat (triglycerides/fat) 53 | Section 1 Biological roles 54 | 第一节生物角色 55 | • Energy stores : 9000 cal/g fat; 4100 cal/g protein; 56 | 4200 cal/g monosaccharide 57 | 4100大卡/ g蛋白; 58 | 4200大卡/ g单糖 59 | • To supply indispensable fatty acids 60 | •提供不可或缺的脂肪酸 61 | • Structural components of biological membranes 62 | •结构组成的生物膜 63 | • To facilitate the absorbance of liposoluble vitamins 64 | (脂溶性维生素) by human bodies 65 | • Extracellular and intracellular messengers 66 | •促进脂溶的维生素的吸收 67 | (脂溶性维生素) 68 | •细胞外和细胞内信使 69 | • Transporter 70 | •运输 71 | • Hormones 72 | •激素 73 | Why lipids are used for storage of energy? 74 | 为什么油脂用于存储的能量? 75 | • The carbon in lipids (mostly CH2) 76 | is almost 77 | completely reduced (so its oxidation yields the 78 | most energy possible). 79 | • Lipids are not hydrated (as mono- and polysaccha 80 | rides are not), so they can pack more closely in sto 81 | rage tissues 82 | •碳在脂质(主要是CH2) 83 | 几乎是 84 | 完全(所以它氧化收益率降低 85 | 大多数能源可能)。 86 | •脂质不水化(mono -和polysaccha 87 | 骑没有),所以他们可以在中途包更密切 88 | 愤怒的组织 89 | Result: 90 | lipids have ~6 more energy of 91 | corresponding amount of proteins or glycogen 92 | 结果: 93 | 脂质~ 6更多的能量 94 | 相应数量的蛋白质或糖原 95 | the 96 | 的 97 | 体内脂肪含量，男性多还 98 | 是女性多？ 99 | Body fat content, men also 100 | Are women more? 101 | 人类身体脂肪有保温功 102 | 能么？ 103 | The human body fat have heat preservation function 104 | Can it? 105 | 为什么女生比男生怕冷？ 106 | Why do girls afraid of the cold than boys? 107 | Section 2 Classification of lipid 108 | 第二节脂类的分类 109 | Lipids may be classified in many different ways. Lipids can 110 | be subdivided into the following classes according to the che 111 | mical compositions: 112 | 脂质可以 113 | 被细分为以下类根据切 114 | 米卡尔成分: 115 | Simple lipid: fatty acids 116 | and glycerol 117 | 简单的脂质:脂肪酸 118 | 和甘油 119 | Triacylglycerols; Wax ester 120 | 蜡酯 121 | compound lipid 122 | 复合脂质 123 | Phospholipids; Sphingolipids; 124 | Sphingolipids; 125 | lipoprotein; glycoprotein 126 | 糖蛋白 127 | derived lipid 128 | 衍生脂质 129 | Isoprenoids; steroids 130 | 类固醇 131 | Section 3 Triacylglycerols 132 | 第三节甘油三酯 133 |  Triacylglycerols are esters of glycerol with three fatty 134 | 甘油三酯是甘油三脂肪酸酯 135 | acid molecules. 136 | 酸分子。 137 |  Most triacylglycerol molecules contain fatty acids of 138 | 大多数三酰甘油分子含有脂肪酸 139 | varying lengths; the fatty acids may be unsaturated, 140 | 可以不饱和脂肪酸, 141 | saturated, or combination. 142 | 饱和,或组合。 143 |  Depending on their fatty acid compositions, 144 | 取决于他们的脂肪酸组成, 145 | triacylglycerol mixtures are referred to as fats or oils. 146 | 三酰甘油混合物被称为脂肪或油。 147 | Simple triacylglycerol (单纯甘油酯) : identical fatty acids 148 | Mixed triacylglycerol (混合甘油酯): different fatty acids 149 | Simple triacylglycerol (pure glyceride) : identical fatty acids 150 | Mixed triacylglycerol (Mixed glyceride) : the company fatty acids 151 | Fatty acids 152 | 脂肪酸 153 |  Fatty acids are monocarboxylic acids (单羧酸) that 154 | typically contain hydrocarbon chains (烃链) of variable 155 | lengths (between 12 and 20 or more carbons). 156 |  Basic formula:CH3(CH2)nCOOH 157 |  Fatty acids are numbered from the carboxylate end. 158 |  Greek letters are used to designate certain carbon 159 | 脂肪酸是一元羧酸(单羧酸) 160 | 通常包含烃链(烃链)的变量 161 | 长度(12到20或更多个碳)。 162 | 基本公式:CH3(CH2)nCOOH 163 | 脂肪酸屈指可数的羧酸盐。 164 | 希腊字母是用来指定特定的碳 165 | atoms. 166 | 原子。 167 | • Saturated or unsaturated .
