I had looked at a library copy of this and saw the missing reaction arrows and held off on buying it. I finally did buy it just to get an introduction.

In the second printing (NOT second edition) the reaction arrows are present - though they are shown as two double-headed arrows rather than the standard two single headed arrows.

But errors remain. For example, the formulas for valine and isoleucine inside the front cover are wrong. They have too many hydrogens on one of the carbon atoms. I don't know how many more of these there are.

It's really not a bad book but the errors drive me nuts.
