OSTI ID:6062721
Progress has been made on the project of determining the structure of pectins. From recent progress, a covalent crosslink between rhamnogalacturonan I (RGI) and xyloglucan was hypothesized and a structure for RGI was proposed. The development of a method to determine the distribution of methyl esterification with pectins also progressed. The degree of methyl esterification of cotton cotyledon cell walls was compared to that of cotton suspension cultures. Cotyledon wall were found to have {approximately}55% of the galacturonic acid esterified whereas suspension culture wall were only about 14% methyl esterified. 10 refs. (SM)
