Cellulose and fiber are related but not identical. Cellulose is a type of carbohydrate and the main component of plant cell walls. It's a complex carbohydrate (polysaccharide) that forms the structural framework of plants. On the other hand, fiber refers to the dietary material containing substances like cellulose, lignin, and pectin, which are resistant to the action of digestive enzymes. Dietary fiber can be soluble or insoluble, with cellulose being a significant type of insoluble fiber. This means all cellulose is fiber, but not all fiber is cellulose; dietary fiber includes a range of other compounds. Thus, while closely related in the context of diet and nutrition, they serve different roles and are not synonymous.

All living organisms share a set of 20 common amino acids that are used to build proteins, essential for life's functions. These amino acids are encoded by the universal genetic code and serve as the building blocks of proteins across various life forms, from simple bacteria to complex humans. This shared biochemical foundation underscores the evolutionary connections among all forms of life and highlights the fundamental principles that govern biological structures and processes. Each of these amino acids plays a unique role in protein structure and function, contributing to the diverse array of proteins necessary for organisms' survival, growth, and reproduction.
