Jhan,
you are right that glutathione is a key nutrient in the fight against candida being the body's most important anti-oxidant and is very often low in those with candida.
Glyconutrients are something else though - they are complex saccharide (sugar) molecules whose importance in nutrition and health are only just being recognized.
Read "Sugars that heal" - a fascinating book on the importance of glyconutrients.
