Figure 1 Metabolism of Glutamine and Glutamate in Intestinal Epithelial Cells and Immune Cells: Their Function as Energy Substrate and Protein Precursors It is well-established that glutamine and glutamate are important energy substrates for intestinal epithelial cells (IECs) and immune cells, especially during periods of rapid growth (86)
Because of this, some research protocols may prefer: 3ml syringes for higher-volume administration protocols Slightly larger gauge needles to improve drawing and administration flow Commonly Used Research Needle Sizes 25G27G needles are commonly used in certain research settings Higher-volume protocols may draw more easily with slightly larger gauge needles compared with standard insulin syringes Administration Research Contexts Research protocols commonly investigate: Subcutaneous administration Intramuscular administration depending on: Research design Volume administered Experimental protocol structure Experimental protocol preference Higher-volume Glutathione research protocols are commonly investigated using intramuscular administration in certain research contexts due to the increased solution volume compared with many peptide formulations
