Endospermic Legumes

Most of the galactose and mannose produced in the endosperm of all these legumes is absorbed by the cotyledons and further metabolized. Several workers have proposed that these sugars are rapidly phosphorylated (to Gal-l-P and Man-6-P). If not directly used for energy metabolism they might be transformed to sucrose and even to starch (this accumulates in fenugreek cotyledons) which

Most work on carbohydrate and protein reserve deposition in dicots has been carried out using commercially important non-endospermic legumes, particularly the garden pea Pisum sativum), field pea (Pisum arvense) and broad bean, field bean or horse bean Vida faba), with fewer studies on the french bean or bushbean Phaseolus vulgaris) and soybean Glycine max). 

Finally a word about the endospermic legumes. As we have mentioned previously, the galactomannan reserves of the endosperm of these seeds might be more important for retention of water within the seed to allow early embryo growth than for the provision of nutrients. The cotyledons of these legumes are usually rich in fats and protein but their mobilization does not appear to have received any attention. 

Like guaran, and the endosperm polysaccharides of other legumes, locust bean (carob)gum [9000-40-2] is also a galactomaiman. Like guaran, it has a linear backbone of (1 — 4)-1inked P-D-mannopyranosyl units. However, in locust bean gum, approximately one of every 3.9 P-D-mannopyranosyl units, on the average, is substituted with an a-D-galactopyranosyl unit attached at 0-6. 

Guar gum comes from the endosperm of the seed of the legume plant Cyamopsis tetragonoloba. Cyamopsis tetragonoloba is an annual plant, grown in arid regions of India as a food crop for animals.
