1-1试以千卡/摩尔为单位,计算相应于以下各值的能 量:(a)240毫微米,(b)480毫微米,(c)6.1微米,(d12.2 微米,(e)1700厘米1,()3400厘米一和(g)34,000厘米-1 解:若以千卡/摩尔为单位,则能量可按如下简单公式计 算

1. Lipids encompass a large and diverse group of organic compounds 1.1 Lipids are broadly defined as biological molecules that are soluble in organic solvents. 1.1.1 Lipids are usually extracted from biological materials by nonpolar solvents like ether, chloroform(氯仿), benzene(苯). 1.2 The biological functions of lipids are diverse. 1.2.1 Certain lipids(e.g., triacylglycerols(三脂酰甘油), commonly called fats) serve as efficient reserves for the storage of energy

一、视线水平,正确读数A;仪器不平,错误读数A′。 二、在像方光路上设置一光学元件,使水平视线偏转β角仍能到达0′点,得到正确读数,必须有af= g

一、有氧氧化的三个阶段G2丙酮酸(同酵解) 2丙酮酸 2乙酰辅酶A 2乙酰辅酶ATCA循环 在有氧时,丙酮酸可进入线粒体内氧化脱羧,生成乙酰辅酶A再 进入三羧酸循环:

1、概念 维生素是机体维持正常生命活动所必不可少的一类有机物质。人体不能合成。 2、发现 孙思邈(581-682):动物肝脏治疗夜盲证,谷皮 汤熬粥治疗脚气病 1886-1897:荷兰人 Eijkman在米糠中发现了治疗“ 脚气病”的“保护因素”。 Grijins证明米糠中含有 一种“营养因素”,并提出“营养缺乏症”的概念 1906:英国 F.G. Hopkins通过小鼠实验得出结论, 维生素是正常膳食中的必需辅助因子

1 Stationarity and unit Root testing WHy do we need to test for Non-Stationarity? The stationarity or otherwise of a series can strongly influence its behaviour and properties -e.g. persistence of shocks will be infinite for nonstationary series Spurious regressions. If two variables are trending over
