Nutritional Science Overview of Amino Acids
Protein Metabolism
Amino acids are the building blocks of proteins. In protein synthesis, ribosomes translate messenger RNA into polypeptide chains, linking amino acids through peptide bonds. The amino acid composition of dietary proteins influences the profile of amino acids available for cellular processes.
Essential vs. Non‑Essential Amino Acids
Essential amino acids must be obtained through diet, while non‑essential amino acids can be synthesized by the body from other precursors. The balance of these amino acids determines the net anabolic or catabolic state of tissues.
Branched‑Chain Amino Acids and Muscle Physiology
BCAAs stimulate muscle protein synthesis via activation of the mTOR pathway. Leucine, in particular, is a key signal for initiating translation initiation complexes. Isoleucine and valine serve as substrates for energy production during prolonged exercise.
Role of Amino Acids in Metabolic Pathways
Amino acids participate in numerous metabolic routes, including gluconeogenesis, urea cycle, and neurotransmitter synthesis. For instance, tryptophan is a precursor to serotonin and melatonin, influencing mood and sleep cycles.
Nutritional Science Overview of Minerals
Microminerals as Cofactors
Trace elements such as zinc and selenium function as cofactors for enzymes involved in antioxidant defense and DNA repair. The deficiency of these minerals can impair immune function and increase oxidative stress.
Macrominerals and Structural Functions
Calcium and phosphorus are major constituents of bone matrix, while magnesium is integral to ATP stabilization and muscle relaxation. Potassium and sodium regulate electrical gradients across cell membranes, essential for neuronal signaling.
Mineral Homeostasis and Transport
Minerals are absorbed in the gastrointestinal tract through active and passive transport mechanisms. Absorption efficiency depends on dietary context, competing ions, and the presence of binding ligands such as phytates or oxalates.
Clinical Significance of Mineral Deficiencies
Deficiencies can manifest in various ways: hypocalcemia leads to tetany, iron deficiency causes anemia, while magnesium deficiency can trigger arrhythmias and muscle cramps.
Manufacturing Processes
