I. Choose the Correct Answer 1. An object moves in the xy plane with an acceleration that has a positive x component. At time=0 the object has a velocity given by=3i +0j. What can be concluded about the y component of the acceleration?

1. General studies of the peptide bond 1.1 The peptide(O=C-N-H) bond was found to be shorter than the C-N bond in a simple amine and atoms attached are coplanar. 1.1.1 This was revealed by X-ray diffraction studies of amino acids and of simple dipeptides and tripeptides. 1.1.2 The peptide (amide) bond was found to be about 1.32 A (C-N single bond, 1.49; C= double bond, 1.27), thus having partial double bond feature (should be rigid and unable to rotate freely)

1. Early studies on the peptide(protein) structure 1.1 The peptide(o=c-n-h) bond was found to be shorter than the C-N bond in a simple amine and atoms attached are coplanar. 1.1.1 This was revealed by X-ray diffraction studies of amino acids and of simple dipeptides and tripeptides

一、隐函数概念:隐函数是表达函数的又一种方法 1.隐函数及其几何意义:以F(x,y)=0为例作介绍 2.隐函数的两个问题:i>隐函数的存在性>隐函数的解析性质
