Glycine is a non-essential amino acid that plays a vital role in various metabolic processes. It's classified as glucogenic, meaning it can be converted into glucose for energy.

Glycine is a key component of purine bases, which make up DNA and RNA. Specifically, it contributes to the carbon atoms at positions 4 and 5, as well as nitrogen atom 7.

Glutathione is a tripeptide composed of glutamate, cysteine, and glycine. It acts as a powerful antioxidant, protecting cells from damage caused by free radicals.

Creatine is a molecule used by muscles for energy during intense activity. It's synthesized from glycine, arginine, and methionine.

Glycine is a crucial amino acid for collagen synthesis, a protein that provides structural support to tissues and organs. It's present in every third position in the collagen helix, ensuring its stability.

Glycine is conjugated with primary bile acids, like cholic acid, to form glycocholic acid, a component of bile that aids in fat digestion.

Glycine can be converted into serine, another amino acid, through the action of serine hydroxymethyltransferase.

Glycine conjugates with toxic benzoate, a byproduct of certain metabolic processes, to form hippuric acid, a non-toxic compound that can be excreted.

A non-essential amino acid that serves as a precursor for various important biomolecules, including glycine, cysteine, and sphingosine.

An essential amino acid involved in the biosynthesis of various critical compounds, including creatine, polyamines, and S-adenosyl methionine (SAM).

This non-essential amino acid is synthesized from α-ketoglutarate and plays a crucial role in various metabolic processes.

A semi-essential amino acid that can be synthesized from glutamate by microorganisms. It is involved in the production of various important compounds, including creatine, urea, and nitric oxide.

An essential amino acid that serves as a precursor for various important compounds, including niacin, serotonin, and melatonin.

The amino acid tyrosine is the precursor for the thyroid hormones T3 and T4. These hormones play a vital role in regulating metabolism.

Melanin is responsible for pigmentation in various tissues, including the eyes, hair, and skin. It serves as a protective pigment against UV radiation.

These are byproducts of bacterial activity in the large intestine, formed from the breakdown of tyrosine. They can contribute to the foul odor of feces.
