What is a monosaccharide

The video explains the process of photosynthesis, highlighting its role in producing oxygen and sugars like glucose, which are essential for life. It delves into the structure and importance of monosaccharides, such as glucose, fructose, and galactose, and introduces disaccharides and polysaccharides. The video also covers the properties of monosaccharides, including their solubility and structural forms.
