The main difference between glycine and glycinate is that glycine is the simplest amino acid and has the chemical formula C2H5NO2, whereas glycinate is the conjugate base of glycine, which is formed when glycine loses its acidic proton (H+) from the carboxyl group.
Glycine and glycinate are related compounds with differences in their chemical forms and applications. While glycine is a fundamental amino acid, glycinate refers to a chelated or salt form of glycine.

What is Glycine
Glycine is an α-amino acid, meaning it contains an amino group (-NH2) and a carboxyl group (-COOH) attached to the same carbon atom, known as the α-carbon. Additionally, it carries a hydrogen atom as its side chain (R group). Glycine is one of the 20 amino acids that make up the building blocks of proteins. During protein synthesis, ribosomes incorporate glycine into the growing polypeptide chains, contributing to the primary structure of proteins. Moreover, it is an essential amino acid.
Glycine is a critical component of collagen, the most abundant protein in the human body. Collagen provides structural support to the skin, joints, bones, and connective tissues. Glycine supplementation, often in the form of collagen supplements, is believed to support skin health, skin elasticity, and wound healing. In the central nervous system, glycine serves as an inhibitory neurotransmitter. It helps regulate neuronal excitability by opening chloride channels in neurons, reducing their activity, and preventing excessive signaling. Glycine receptors help in motor control and the processing of sensory information.
Glycine also plays a crucial role in the synthesis of glutathione, a powerful antioxidant. Glutathione helps neutralize harmful free radicals and detoxify various substances in the body, including drugs, pollutants, and toxins. Glycine supplementation may support the body’s antioxidant and detoxification pathways. Moreover, glycine is involved in the process of gluconeogenesis, where the body synthesizes glucose from non-carbohydrate precursors, such as amino acids and glycerol. This metabolic pathway is essential for maintaining blood glucose levels during fasting and low-carbohydrate diets.
What is Glycinate
Glycinate, also known as glycine anion, is derived from glycine, which is the simplest amino acid. Glycine consists of a hydrogen atom (H) as its side chain, an amino group (-NH2), and a carboxyl group (-COOH) attached to the same carbon atom (α-carbon). When glycine loses its acidic proton (H+) from the carboxyl group, it forms the negatively charged glycinate ion.
Glycinate, in its salt form, has a wide array of practical applications in different industries:
Magnesium glycinate is a popular dietary supplement that combines magnesium with glycine. This form of magnesium is known for its high bioavailability and is commonly used to support muscle function, relaxation, and overall well-being.
Zinc glycinate is useful in pharmaceutical formulations and dietary supplements. It is highly bioavailable and often helps to address zinc deficiencies, support the immune system, and promote skin health.
Copper glycinate is useful in agriculture as a chelated micronutrient. It helps improve the availability of copper to plants, ensuring healthy growth and development. Copper glycinate is also useful in skincare products.
Calcium glycinate is used as a food additive in the food industry. It can serve as a source of calcium, an essential mineral, while also helping to enhance the taste and texture of certain products.
Similarities Between Glycine and Glycinate
- Both glycine and glycinate are amino acids, with glycine being the parent amino acid.
- People can obtain them from the diet.
Difference Between Glycine and Glycinate
Definition
Glycine is the simplest amino acid and has the chemical formula C2H5NO2, whereas glycinate is the conjugate base of glycine, which is formed when glycine loses its acidic proton (H+) from the carboxyl group.
Charge
While glycine is electrically neutral, glycinate is negatively charged.
Nature
Glycine is a non-essential amino acid, meaning that the body can synthesize it on its own, and it’s also obtained from dietary sources. Glycinate is commonly used in mineral supplements, where it is bound to minerals like magnesium or zinc.
Conclusion
In brief, glycine is the basic amino acid, while glycinate refers to a form of glycine that is bound to another molecule, often a mineral. Glycinate forms are typically useful as supplements and medications due to their improved absorption and reduced gastrointestinal irritation compared to free glycine. Thus, this is the main difference between glycine and glycinate.
