Substrate-level phosphorylation is defined as the production of ATP or GTP following the transfer of a phosphate group from a substrate to ADP or GDP.[2] The energy released from the cleavage of a high-energy bond of the substrate facilitates the formation of the phosphoanhydride bond.[1] Part of this energy drives the reaction toward nucleotide triphosphate … Continue reading Substrate-level phosphorylation: what it is, examples, and functions→ The post Substrate-level phosphorylation: w...| Tuscany Diet

Glucogenic amino acids are defined as amino acids whose carbon skeletons can be fully or partially catabolized into precursors for glucose synthesis or gluconeogenesis, hence the name.[2] Amino acids are the building blocks of proteins. When their pool meets the cellular needs for protein synthesis, since there are no amino acid stores in the body … Continue reading Glucogenic amino acids: definition, list, and role in prolonged fasting→ The post Glucogenic amino acids: definition, list, ...| Tuscany Diet
