Summary
Human skeletal muscle protein is composed of the full set of 20 standard amino acids—alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine. Neither selenocysteine (U) nor pyrrolysine (O) are typical constituents of muscle protein.

Keywords: Muscle protein synthesis, Amino acid supplementation, Branched-chain amino acids, Creatine, Glutamine, β-alanine · Amino acids are the building blocks for all life forms. There are 21 amino acids that make up human tissue proteins, with selenocysteine now included in the list and utilized for synthesizing proteins and essential molecules that fulfill significant physiological functions related to nutrition, sensory perception, and biological regulation [1–3]. These amino acids can be classified into essential amino acids (EAA, incapable of endogenous synthesis and must be obtaine

Generally, leucine is metabolized to α-ketoisocaproic acid (KIC) by branched-chain amino acid aminotransferase 2 (BCAT2) in the skeletal muscle. Most of the KIC is converted to isovaleryl-CoA, and only 5–10% of KIC is converted to HMB in the liver [47]. HMB has been used as an ergogenic supplement to increase muscle mass and strength in humans. Several studies have revealed that HMB and leucine stimulate protein synthesis and reduce muscle protein breakdown.

Thus, leucine tolerance reflects a balance between unmeasured protein losses (e.g., sloughed skin, hair, and nails) and the net accretion of body protein, which in turn is linked to growth rate [16]. During metabolic crises, changes of plasma leucine trace whole body protein turnover, which can be quantified if one assumes the human body is 10–12% protein [17], protein is 7–8% leucine by weight [18,19], and free leucine (molecular weight 131 mg/mmol) is evenly distributed in total body water (Fig.

Muscle exists in dynamic equilibrium whereby the influx of amino acids (AAs) and the resulting increases in muscle protein synthesis (MPS) associated with the intake of dietary proteins cancel out the efflux of AAs from muscle protein breakdown that occurs between meals.
