Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as for carbohydrates , lipids , proteins and fermentation products ...
Mineral nutrients cycle through this marine food chain, from bacteria and phytoplankton to flagellates and zooplankton, which are then eaten by other marine life. [ 55 ] [ 56 ] In terrestrial ecosystems , fungi have similar roles as bacteria, mobilizing minerals from matter inaccessible by other organisms, then transporting the acquired ...
Choline is an essential nutrient and its primary function within the human body is the synthesis of cellular membranes, [16] although it serves other functions as well. It is a precursor molecule to the neurotransmitter Acetylcholine which serves a wide range of functions including motor control and memory.
