👉 Sialic is a term used in chemistry and biochemistry. It refers to a type of carbohydrate that has a glycosyl group attached to its side chain, which can be either an α-1,4-glycan or an α-1,6-glycan. This type of carbohydrate can be found on the surface of plant cells and is involved in several biological processes such as cell wall formation, starch synthesis, and energy production.
