有机化学的 R 是对烃链的通称。立体化学(stereochemistry)的 R 表示一个碳原子附近右旋式(顺时针)分子排列方式,判定的方式依照Cahn Ingold Prelog priority rules 。生物化学的 R 表示精氨酸(arginine) 。化学反应的r表示单位容量的莫耳生成速率。医学医学的R 是指人的呼吸频率。例如:正常的人的R≈16~20次/分...

Stereochemistry How to Determine the R and S configuration What is the R and S Configuration and why do we need it? If we name thesetwo alkyl halidesbased on theIUPAC nomenclaturerules, we get the name as 2-chlorobutane for both:
The structure is S because the lowest priority is not a "dash" even after this particular rotation...even though the highest priority is a "wedge." Of course, if you could be bothered enough, you could rotate it to the point where OH was a wedge and H was a dash, but this maneuver...
r的英文字母的音标是英 [ɑː] 美 [ɑr] 。释义：n. 英语字母中的第十八个字母 abbr. 电阻（resistance）；比率（ratio）；医生处方（recipe）R由腓尼基语的第20个象形字母演变而来。腓尼基人称之为resh，意为“头”。从古罗马时代起，R一直被称作littera canīna（拉丁文，狗的字母，英文...
Draw a Fischer projection of (+)-arabinose, and identify it as a D sugar or an L sugar. (a) Name the structure shown, including the stereochemistry. Redraw the structure using (b) a Newman projection and (c) a Fischer projection. Calculate the term that can arise from the configuration...
stereochemistryterminologyThe R/S system, universally applied for indicating the absolute configuration of a structure, is extremely adept for conveying the absolute configuration unequivocally. However, it suffers from one limitation, viz that due to CIP priority rules the rankings of the ligands ...
