SOLUTIONS TO TEXT PROBLEMS 19.1 (b) The four carbon atoms of crotonic acid form continuous chain. Because there is a double bond between C-2 and C-3, crotonic acid is one of the stereoisomers of 2-butenoic acid. The chem
SOLUTIONS TO TEXT PROBLEMS 24.(b) A benzyl group(C., CH2) is ortho to the phenolic hydroxyl group in o-benzylphenol. OH CH2C.Hs (c)Naphthalene is numbered as shown. 3-Nitro-I-naphth has a hydroxyl group at C-1 and a nitro group
The triacylglycerol shown in text Figure 26.2a, with an oleyl group at C-2 of the glycerol unit and two ste earyl groups at C-I and C-3, yields stearic and oleic acids in a 2 I molar ratio on hydrolysis. A constitutionally isomeric structure in which the oleyl group is attached to C-1 of glycerol would yield the same hydrolysis products

The best known and most widely used active packaging technologies for foods today are those engineered to remove undesirable substances from the headspace of a package through absorption, adsorption or scavenging. To achieve this goal a physical or chemical absorbent or adsorbent is incorporated in the packaging material or added to the package by means of a sachet. In most publications
