WebNov 20, 2006 · L-Tryptophan is one of nine essential amino acids for humans—“essential” in that the body cannot synthesize them, so they must be part of the diet.Fortunately, tryptophan is a constituent of many common foods, especially ones that are high in protein. In 1901, British biochemists Frederick Gowland Hopkins and Sydney W. Cole discovered … WebApr 14, 2024 · 1 Introduction. Cholesterol, a major component in cell membrane bilayers, is essential for membrane structure and fluidity. The brain is the most cholesterol-enriched organ and a human brain contains about 20–25% of the body's cholesterol; [] this high density suggests that cholesterol has a critical function in the brain. Age-related …
