Ethanolamine is a metabolite of the nonessential amino acid serine. In the presence of adequate levels of functional B-6 (P-5-P) serine is enzymatically converted to ethanolamine.

Ethanolamine, Plasma is a marker measured in an Amino Acid Profile, Quantitative (Plasma) panel, which plays an important role in various bodily functions. Ethanolamine is a key component of phospholipids, which are essential building blocks of cell membranes. This compound is involved in the synthesis of phosphatidylethanolamine, a crucial phospholipid that helps maintain the structural integrity and fluidity of cell membranes. Beyond its structural role, ethanolamine is also involved in cell signaling and neurotransmission, particularly in the central nervous system. It serves as a precursor for the synthesis of acetylcholine, a vital neurotransmitter that affects muscle contraction, memory, and learning. Normal levels of ethanolamine in the plasma indicate proper cellular function and membrane stability.

Ethinyl estradiol is an estrogen receptor agonist commonly used in combined oral contraceptives. It is a synthetic derivative of estradiol. In the liver it stimulates the synthesis of SHBG, increasing SHBG levels by 2- to 4-fold in women, which has the effect of binding more circulating testosterone and reducing free testosterone concentrations by 40-80%. The suppression of free testosterone levels may impact female sexual desire.

Ethylmalonate, together with Adipate and Suberate, gives information about your ability to process fatty acids.

Ethylmalonate, which comes from the breakdown of butyrate, has a carnitine-dependent pathway and can accumulate with an insufficient amount of carnitine. Dietary fat, carbohydrate, and protein are all broken down to produce energy using pathways that require vitamin B2 (riboflavin).

Note: These tests are used to check for rare metabolic disorders, usually in infants. There is no apparent reason nor benefit to checking ethylmalonic and methylsuccinic acid levels in adults who aren’t suspected to have rare genetic disorders.

Ethylmalonic acid is a significant marker often evaluated in clinical settings to provide insights into metabolic processes within the body. Elevated levels of this compound can indicate a variety of metabolic disturbances, particularly those involving fatty acid oxidation and mitochondrial function.

Ethylparaben belongs to the paraben family and is an anti-fungal agent often used in a variety of cosmetics and personal-care products. It is also used as a food preservative. Although parabens are generally considered safe when used in low percentages, a study claimed to have found a link between parabens and breast cancer.

Etiocholanolone is a DHEA metabolite that is excreted in the urine. It is produced from androstenedione and the 5-beta-reductase metabolic pathway. It is helpful in evaluating adrenal and androgen function.
