Possible Interaction: Glucosamine and Vitamin A

“The results indicate that retinol increases the amount of mannose and glucosamine incorporated into cellular glycoconjugates.”

“… vitamin A … glucosamine incorporation into glycoproteins or glycoprotein fragments to above normal levels.5.6 Vitamin A deficiency is also associated with a reduction in the … mucins.10,11 Mucins are high molecular weight glycoproteins that consist mostly of carbohydrate and probably play a role in epithelial surface function.”

“It was also found that vitamin A had a greater effect on the incorporation of [3H]glucosamine than on [14C]serine into the secreted mucins, particularly at the higher retinyl acetate concentrations.”
