Beta-Alanine

Amino Acid Analysis, Quest Diagnostics

Optimal range:   0 - 5 umol/L

β-alanine is a breakdown product of carnosine and anserine, which are dipeptides from meat consumption. Although β-alanine’s properties are limited, its relationship to carnosine makes it important. Both have antioxidant properties. And, as previously mentioned, carnosine is critical for pH buffering in skeletal muscle during exercise, but its formation can be limited by enzymatic factors.

For this reason, supplementation with β-alanine is sometimes used to enhance carnitine and therefore improve athletic performance. In addition to diet and supplementation, β-alanine can also be endogenously produced. This occurs via degradation of uracil in the liver but it can also be made by intestinal bacteria such as E. coli.

Optimal range:   1.1 - 9 umol/L

Beta-alanine is is a non-essential amino acid.

What are amino acids?

Non-essential amino acids can be made by the body, so they don’t have to be provided by food. Amino acids are the building blocks of proteins.

Beta-alanine

Urine

Optimal range:   0 - 35 qmol/24 hours

Beta-alanine is a non-essential amino acid involved in various metabolic processes in the body. It's not typically required from the diet because the body can produce it. In medical testing, the levels of beta-alanine in urine are measured to assess its concentration in the body.

Under normal conditions, beta-alanine is efficiently converted into other substances, including alpha-ketoglutarate, through a process that depends on vitamin B-6.

Beta-aminoisobutyrate

Amino Acid Profile, Qn (Urine), LabCorp

Optimal range:   0.5 - 807.9 umol/g Cr

Beta-aminoisobutyric acid (BAIB) is an amino acid end product of the pyrimidine metabolism. It is excreted in small quantities into the urine in almost all human beings. Thymine, released when RNA and DNA are degraded, enters a catabolic pathway that leads to Beta-Aminoisobutyric Acid.

Amino Acids test [Great Plains Laboratory / Doctor's Data], Doctor's Data

Optimal range:   0 - 160 qM/g creatinine

Beta-aminoisobutyric acid (also known as 3-aminoisobutyric acid) is a non-protein amino acid formed by the catabolism of valine and the nucleotide thymine. It is further catabolized to methylmalonic acid semialdehyde and propionyl-CoA. Levels are controlled by a vitamin B6-dependent reaction in the liver and kidneys. β-aminoisobutyric acid can also be produced by skeletal muscle during physical activity.

Beta-glucuronidase

2200 GI Effects Comprehensive Profile - Stool, Genova Diagnostics

Optimal range:   368 - 6266 U/g

Beta-glucuronidase is an enzyme which is produced by colonocytes and by some intestinal bacteria (particularly E. coli, but also Ruminococcus, Bacteroides, Eubacterium, Peptostreptococcus, Staphylococcus, and Clostridium).

Beta-glucuronidase breaks down complex carbohydrates and increases the bioavailability and reabsorption of plant polyphenols (lignans, flavonoids, ceramides, and glycyrrhetinic acid).

Beta-glucuronidase deconjugates glucuronide molecules from a variety of toxins, carcinogens, hormones (i.e. estrogens) and drugs.

Deconjugation permits reabsorption via enterohepatic circulation, with the potential to elevate systemic levels of potentially harmful compounds and hormones.

Stool

Adult Gut Health Test, Tiny Health

Optimal range:   4000 - 9400 U/h*g

Beta-glucuronidase is an enzyme produced by various types of bacteria in the gut and plays a key role in gut health. It is involved in the process of deconjugation of glucuronides, which are compounds formed in the liver to help detoxify substances like hormones, toxins, and drugs. Once these glucuronides reach the gut, beta-glucuronidase can break them down, leading to the reabsorption of the substances that were previously detoxified, which can have both beneficial and harmful effects depending on the compounds involved.

ß-Hydroxybutyrate is a metabolic marker of blood sugar utilization and insulin function.

Beta-hydroxybutyrate is 1 of 3 sources of ketone bodies. Its relative proportion in the blood (78%) is greater than the other 2 ketone bodies, acetoacetate (20%) and acetone (2%). During carbohydrate deprivation (starvation, digestive disturbances, frequent vomiting), decreased carbohydrate utilization (diabetes mellitus), glycogen storage diseases, and alkalosis, acetoacetate production increases.
