SAM Cycle (S-Adenosylmethionine Cycle)

Choline and Betaine Degradation Pathways

Corrin/B12 Biochemistry: Methionine Synthase Reductase

This video discusses the health benefits of millet. Millet's high concentrations of nutrients, such as calcium and fiber, make it a healthy whole grain choice, especially for people at risk of diabetes, osteoporosis, and other...

Lesson on One Carbon Metabolism, the role of tetrahydrofolate and the folate cycle. Tetrahydrofolate (THF) is derivative of folic acid (Vitamin B9), which is acquired from dietary sources. Tetrahydrofolate (THF) in various forms...

Lesson on Methionine Metabolism and the Activated Methyl Cycle. Methionine is a sulfur-containing essential amino acid, which can be processed within the activated methyl cycle to produce s-adenosyl methionine (SAM) and...

Lesson on Histamine Synthesis and Metabolism from the amino acid Histidine. Histamine is a biogenic amine that acts as a local signaling molecule and a neurotransmitter in the central nervous system. Histamine is produced from the...

Shine-Dalgarno/Kozak Sequences & 70S Ribosome Assembly

Lesson on Carnitine Biosynthesis. Carnitine is an important metabolite that is required for transportation of long chain fatty acids into the mitochondria via the Carnitine shuttle. Carnitine can be derived from dietary sources or from...

Lesson on Serotonin and Melatonin Synthesis from the amino acid Tryptophan. Tryptophan is an essential amino acid, which is used to produce the monoamine neurotransmitter serotonin and the hormone melatonin. Serotonin is important in...
