  2. β-Alanine - Wikipedia

    en.wikipedia.org/wiki/Β-Alanine

    β-Alanine (beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon (i.e. the carbon two carbon atoms away from the carboxylate group) instead of the more usual α-carbon for alanine (α-alanine). The IUPAC name for β-alanine is 3-aminopropanoic acid.

  4. Essential amino acid - Wikipedia

    en.wikipedia.org/wiki/Essential_amino_acid

    The distinction between essential and non-essential amino acids is somewhat unclear, as some amino acids can be produced from others. The sulfur-containing amino acids, methionine and homocysteine, can be converted into each other but neither can be synthesized de novo in humans. Likewise, cysteine can be made from homocysteine but cannot be ...

  5. Protein (nutrient) - Wikipedia

    en.wikipedia.org/wiki/Protein_as_nutrient

    There, most of the peptides are broken into single amino acids. Absorption of the amino acids and their derivatives into which dietary protein is degraded is done by the gastrointestinal tract. The absorption rates of individual amino acids are highly dependent on the protein source; for example, the digestibilities of many amino acids in ...

    His dietary views are mentioned in his book Unleashing the Wild Physique, published in 1984. He recommended the use of numerous supplements, including desiccated liver tablets, free form amino acids, 225 mcg kelp tablets, Vitamin C tablets, digestive enzymes and raw glandular such as adrenal and orchic tablets.

  7. Biological value - Wikipedia

    en.wikipedia.org/wiki/Biological_value

    Amino acid composition is the principal effect. All proteins are made up of combinations of the 21 biological amino acids. Some of these can be synthesised or converted in the body, whereas others cannot and must be ingested in the diet. These are known as essential amino acids (EAAs), of which there are 9 in humans.

  8. Protein-sparing modified fast (diet) - Wikipedia

    en.wikipedia.org/wiki/Protein-sparing_modified...

    The concept of "protein-sparing modified fast" (PSMF) was described by George Blackburn in the early 1970s as an intensive weight-loss diet designed to mitigate the harms associated with protein-calorie malnutrition [8] and nitrogen losses induced by either acute illness or hypocaloric diets in patients with obesity, in order to adapt the patient's metabolism sufficiently to use endogenous fat ...

  9. β-Hydroxy β-methylbutyric acid - Wikipedia

    β-Hydroxy β-methylbutyric acid [note 1] (HMB), otherwise known as its conjugate base, β-hydroxy β-methylbutyrate, is a naturally produced substance in humans that is used as a dietary supplement and as an ingredient in certain medical foods that are intended to promote wound healing and provide nutritional support for people with muscle wasting due to cancer or HIV/AIDS.
