Abstract: 
Polysaccharides also known as glycans are ubiquitous biopolymers that occur widely in nature. They are obtained from renewable sources such as plants, algae and microorganisms like fungi and bacteria. They are getting more attention because they exhibit a wide range of biological activities, such as anti-tumor, immunomodulatory, antimicrobial, antioxidant, anticoagulant, antidiabetic, antiviral, and hypoglycemia activities, making them one of the most promising candidates in biomedical and pharmaceutical fields. In this review, we will discuss the most recent updated biological applications of polysaccharides.
